    Intended Use

    The ETHICON™ 4000 and ETHICON™ 3D Reloads are intended for transection, resection and/or creation of anastomoses. The instruments have applications in multiple open or minimally invasive general, urologic, thoracic, and pediatric surgical procedures. They can be used with staple line or tissue reinforcement materials. The instruments may also be used for transection and resection of liver parenchyma (hepatic vasculature and biliary structures), pancreas, kidney, and spleen.

    Device Description

    The ETHICON™ 4000 Stapler and ETHICON™ 3D Reloads are sterile, single-patient-use instruments that simultaneously cut and staple tissue. There are six staggered rows of staples, three on either side of the cut line. Together, the ETHICON™ 4000 Staplers and ETHICON™ 3D Reloads deliver 3D staples in the first, second, fifth and sixth rows of staples. The third and fourth rows (nearest the knife) maintain the traditional 2D B-formed staples.

    ETHICON™ 4000 60mm Staplers have a staple line that is approximately 60 mm long and a cut line that is approximately 57 mm long. The Subject stapler device is available in three different shaft lengths - Compact, Standard and Long. The shaft can rotate freely in both directions and an articulation mechanism enables the distal portion of the shaft to pivot to facilitate lateral access to the operative site. The device is packaged with a primary lithium Battery Pack that must be installed prior to use. There is embedded software to articulate and initiate firing of the device.

    The instruments are packaged without a reload and must be loaded prior to use. The instrument may be reloaded for a maximum of 12 firings during a single procedure. A Staple Retaining Cap on the reload protects the staple leg points during shipping and transportation. The instruments' lockout feature is designed to prevent a used or improperly installed reload from being re-fired or an instrument from being fired without a reload.

    The staples are permanent implants that provide tissue closure and apposition from the time of implant through the critical phases of healing. The staples remain in place for the patient's lifetime, unless in the opinion of the treating physician, they require removal.

    AI/ML Overview

    Based on the provided FDA 510(k) clearance letter for the ETHICON™ 4000 Stapler and ETHICON™ 3D Reloads (K250835), here's an analysis of the acceptance criteria and the study proving the device meets them:

    Important Note: The provided document is a 510(k) clearance letter, which summarizes the FDA's decision based on the applicant's submission. It does not contain the full details of the studies conducted. Therefore, some information requested (e.g., specific acceptance criteria values, sample sizes for training sets, adjudication methods, details of expert qualifications, and MRMC study effect sizes) is not explicitly stated in this public document. The answers below are derived directly from the content provided and identify where information is not present.


    Acceptance Criteria and Study to Prove Device Meets Acceptance Criteria

    The primary purpose of this 510(k) submission was to expand the indications for use of an already cleared device to include transection and resection of liver parenchyma (hepatic vasculature and biliary structures), pancreas, kidney, and spleen. The acceptance criteria would therefore revolve around demonstrating safe and effective performance of the stapling system in these specific organ tissues.

    Based on the document, the general "acceptance criteria" can be inferred from the types of performance tests conducted and the conclusion statement that the "subject devices passed the functional requirements of the device features" and "have been demonstrated to be safe and effective for the expanded indications for use."

    1. Table of Acceptance Criteria and Reported Device Performance

    As specific quantitative acceptance criteria (e.g., minimum burst pressure, maximum staple height deviation) are not provided in this summary document, we can only infer the categories of performance that were evaluated and determined to be acceptable.

    Acceptance Criteria Category (Inferred)Reported Device Performance (Summary)
    Mechanical PerformancePassed: Subject devices passed the functional requirements of the device features. This implies that the stated mechanical specifications related to staple formation, staple line length, and instrument operation were met.
    Staple Line IntegrityPassed: Nonclinical (bench) tests included "staple line integrity in solid organs." The conclusion states the device passed functional requirements, indicating adequate staple line integrity.
    Staple Form QualityPassed: Nonclinical (bench) tests included "formed staple height" and "staple form quality." The conclusion indicates these were met. The device delivers 3D staples in certain rows and 2D B-formed staples in others; the quality of these forms was assessed.
    Hemostasis Performance (in Solid Organs & Vessels)Passed: Pre-clinical (animal) testing included "hemostasis performance in solid organs and vessels." The conclusion states the device is "safe and effective," implying successful hemostasis in the tested tissues.
    Vessel SealingPassed: Nonclinical (bench) tests included "vessel sealing." The conclusion indicates this was met.
    BiocompatibilityMeets ISO 10993-1: Stated as explicitly met.
    Sterilization & Shelf LifeMet: Stated as EO Sterilization (Stapler) and Gamma Irradiation (Reload) with a 3-year shelf life. These inherently serve as acceptance criteria that were met.
    Safety and Effectiveness for Expanded IUDemonstrated: "The ETHICON™ 4000 and ETHICON™ 3D Reloads have been demonstrated to be safe and effective for the expanded indications for use." This is the overarching acceptance criterion confirmed by the submission.
    Substantial EquivalenceDemonstrated: "performance testing demonstrates that the Subject device performs substantially equivalent to the Predicate device and does not raise any new questions of safety and effectiveness." This is the ultimate acceptance criterion for 510(k).

    2. Sample Size Used for the Test Set and Data Provenance

    • Sample Size for Test Set: Not explicitly stated in the document. The general descriptions refer to "nonclinical (bench) tests" and "pre-clinical (animal) testing," implying a test set was used, but no specific numbers of samples, instances, or animal subjects are provided.
    • Data Provenance:
      • Country of Origin: Not specified. Standard practice for such studies would likely involve labs in the US or collaborating international facilities, but the document does not state this.
      • Retrospective or Prospective: These were prospective studies, as they were conducted specifically to gather data for this 510(k) submission to support the expanded indications for use.

    3. Number of Experts Used to Establish Ground Truth and Qualifications

    This information is not applicable as this submission is for a mechanical surgical stapler and reload system, not an AI or image-based diagnostic device where "ground truth" would be established by human experts in image interpretation. The "truth" in this context is the physical performance and biological outcome (e.g., successful staple formation, hemostasis) confirmed through engineered testing and animal models.

    4. Adjudication Method for the Test Set

    This information is not applicable as this submission is for a mechanical device. Adjudication methods are typically used in studies involving human interpretation or clinical outcomes where there might be inter-reader variability. The "adjudication" in this context would be the rigorous adherence to testing protocols and criteria, verified by engineers and potentially DVMs for animal models.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size

    No, an MRMC comparative effectiveness study was not done. This type of study is relevant for AI or CAD (Computer-Aied Detection/Diagnosis) systems where the performance of human readers (e.g., radiologists) is compared with and without AI assistance. This submission is for a mechanical surgical stapler.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

    This question is not applicable as this is not an AI/algorithm-based device. The "standalone performance" of the device is its mechanical function (stapling, cutting) which was assessed through bench and animal testing.

    7. The Type of Ground Truth Used

    The "ground truth" for this medical device's performance was established through:

    • Bench Test Results: Direct measurement and evaluation of physical characteristics and functional performance (e.g., formed staple height, staple form quality, vessel sealing, staple line integrity) under controlled laboratory conditions. These are objective engineering measurements.
    • Animal Model Outcomes: Direct observation and measurement of biological outcomes in live animal tissues (porcine model for liver, spleen, pancreas, isolated vessels, lung, uterine tissues). "Hemostasis performance" implies direct assessment of whether the stapling achieved effective cessation of bleeding. These are physiological and anatomical "truths."

    8. The Sample Size for the Training Set

    This information is not applicable as this is a mechanical device, not an AI/machine learning algorithm that requires a "training set."

    9. How the Ground Truth for the Training Set Was Established

    This information is not applicable for the same reason as above (not an AI/ML device).


    In summary, the 510(k) clearance for the ETHICON™ 4000 Stapler and ETHICON™ 3D Reloads for expanded indications was based on a combination of rigorous nonclinical (bench) testing to verify mechanical performance and engineering specifications, and pre-clinical (animal) testing to demonstrate in vivo safety and effectiveness, particularly hemostasis performance in the newly indicated solid organs (liver, pancreas, kidney, spleen) and associated vasculature. The acceptance criteria were implicitly met by the successful completion and positive outcomes of these tests, demonstrating substantial equivalence to predicates and no new questions of safety and effectiveness for the expanded uses.

    Intended Use

    The ETHICON™ Total Energy System is intended to supply energy to surgical devices.
    The ETHICON™ Total Energy System is an electrosurgical generator that provides power to monopolar, bipolar, and ultrasonic surgical instruments. It is indicated for surgical procedures requiring cutting or coagulation of soft tissue.

    Device Description

    The subject device, The ETHICON™ Total Energy System, is an electrosurgical generator that integrates Advanced Energy (Advanced Bipolar and Ultrasonic) and Core Monopolar and Bipolar energy modalities into one system, the Ethicon Total Energy System. The subject device consists of two modules: the Communications Module (ETHCM and ETHUSC) and the Energy Module (ETHEM). Atop the Energy Module is the Communications Module and the User Screen. The Communications Module contains the power button and speakers, connects to the User Screen, distributes power to the system, and provides external interfaces for other connectivity to external devices including Ethernet and USB. One or two Energy Modules can be connected to the Communications Module. When two Energy Modules are connected, each Energy Module can independently power any of the energy modalities. This feature allows for simultaneous use of two surgical instruments in one system to support complex surgical procedures where two surgeons are operating on a patient at the same time. The User Screen features a touch-operable graphical user interface (GUI) for system settings adjustment, user profile management, and alarm troubleshooting. The ETHICON™ Total Energy System accessories include a cart for system transport, footswitches (single, double, round), and an output verification key. The cart provides a mobile platform with adjustable shelves and accessory storage. Additionally, the cart has custom features to create stability for the system including cut-outs on the top shelf for holding the rubber feet of a second module layers. Casters provide 360° mobility with locking tabs that lock to prevent unwanted cart movement. Footswitches may be used to control power delivery to connected instruments, enabling surgeons to activate the energy output hands-free. The different footswitches can be used for various energy modalities and instruments. Up to four footswitches can be connected to the Communications Module of the Ethicon Total Energy System at the same time. The footswitches are assigned to the desired instrument port via the User Screen GUI. Output Verification is a service mode of the system used to periodically confirm that the power outputs of each energy modality are within the required specifications. The Energy Output Verification Key is used by biomed/hospital facility servicing personnel to complete this process for annual maintenance on the Energy Module, with on-screen guidance to assist in this process. The ETHICON™ Total Energy System is compatible with Ethicon HARMONIC™, Ethicon ENSEAL™, and Ethicon MEGADYNE™ monopolar and bipolar instruments.

    AI/ML Overview

    The provided FDA 510(k) summary for "The ETHICON™ Total Energy System" does not contain the specific details regarding acceptance criteria and the comprehensive study results typically found in a full scientific report.

    However, based on the information provided, I can infer the general nature of the acceptance criteria and the studies performed, and explain what is missing from a complete answer regarding detailed acceptance criteria and proof of meeting them:

    General Conclusion from the Document:
    The FDA 510(k) summary states, "The subject device showed either equivalent or improved performance compared to the predicate devices and met all functional requirements of its features. It successfully met the acceptance criteria for bench testing, animal studies, usability, and electrical testing, demonstrating no new safety or effectiveness issues compared to the predicate."

    This indicates that acceptance criteria were established and met for various aspects, but the specific, quantifiable criteria and the detailed results proving they were met are not explicitly listed in the provided text.

    Here's an attempt to answer your request based on the available information, highlighting what is present and what is absent:


    1. A table of acceptance criteria and the reported device performance

    Missing Information: The document states that the device "met the acceptance criteria for bench testing, animal studies, usability, and electrical testing" and "demonstrated equivalent output, stability, and thermal spread control" compared to predicates. However, specific quantitative acceptance criteria and their corresponding reported device performance values are not provided in this 510(k) summary. For example, it doesn't state "Acceptance Criterion: Vessel burst pressure > X mmHg, Reported Performance: Y mmHg."

    To illustrate what would be in such a table, based on the mentioned tests:

    AI/ML Overview

    This 510(k) summary is for the ETHICON™ 4000 60mm Staplers and ETHICON™ 3D 60mm Reloads. It focuses on non-clinical testing to demonstrate substantial equivalence to predicate devices.

    1. Table of Acceptance Criteria and Reported Device Performance

    The submission does not explicitly list a table of acceptance criteria with corresponding performance metrics for the reasons stated below. Instead, it indicates that the devices either met or improved upon the predicate devices' performance, or passed functional requirements.

    Test TypeAcceptance Criteria (Inferred from text)Reported Device Performance
    Staple Performance Bench TestingEquivalent to or improved compared to predicate devicesPerformed staple performance equivalence bench testing compared to the predicate, and performed at least equivalently or showed improved performance.
    Device Functional PerformanceMet functional requirements of the subject device featuresPerformed device functional performance bench testing and passed the functional requirements.
    Staple Line StrengthDemonstrated characteristics comparable to predicate devicesPerformed staple line strength product characterization of Subject and Predicate devices, implying comparable strength or meeting specified criteria, though specific metrics are not provided.
    BiocompatibilityCompliant with ISO 10993-1Biocompatibility evaluation was performed according to ISO 10993-1.
    Hemostasis PerformanceAcceptable hemostasis performance in pre-clinical models (details not provided)Pre-clinical data including hemostasis performance was collected in abdominal and thoracic procedures. Result deemed acceptable to demonstrate substantial equivalence, though specific metrics and acceptance levels are not given.

This demonstrates safe and effective staple formation with the 3D staple design.

    2. Sample Size Used for the Test Set and Data Provenance

    The document does not provide specific sample sizes for the test sets used in the non-clinical studies (e.g., staple performance, functional performance, staple line strength, hemostasis, tissue healing).

    The data provenance is from non-clinical studies, which implies laboratory or animal testing rather than human subject data. Pre-clinical data for hemostasis and tissue healing response were conducted in "Abdominal and Thoracic procedures," indicating animal models.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    This information is not applicable as the evaluation relies on non-clinical (bench and pre-clinical animal) testing and not on expert interpretation of human clinical data or images. Ground truth, in this context, would be established by objective measurements and scientific protocols.

    4. Adjudication Method for the Test Set

    This information is not applicable as the evaluation relies on non-clinical testing, not subjective assessments that would require adjudication.

    5. If a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    An MRMC study was not done. This device is a surgical stapler and reload system, not an AI-assisted diagnostic or interpretive device that would involve human readers.

    6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done

    This information is not applicable. The device is a surgical stapler, which is a physical medical instrument, not an algorithm or software-only device.

    7. The type of ground truth used

    The ground truth for the non-clinical tests would be established through:

    • Objective Measurements: For staple performance, functional performance, and staple line strength, measurements of physical properties (e.g., staple formation, closure force, staple line integrity, burst pressure) would serve as ground truth, compared against pre-defined engineering specifications or predicate performance.
    • Histopathology/Pathology and Physiological Measurements: For hemostasis and tissue healing response in pre-clinical animal studies, ground truth would be established through direct observation, macroscopic assessment, histological examination (pathology), and physiological measurements relevant to bleeding control and tissue repair.
    • Compliance with Standards: For biocompatibility, ground truth is compliance with the requirements of ISO 10993-1.

    8. The sample size for the training set

    This information is not applicable. The device is a physical surgical instrument, not an AI/ML algorithm that requires a "training set." The development process would involve extensive engineering design, prototyping, and iterative testing, but not a "training set" in the context of machine learning.

    9. How the ground truth for the training set was established

    This information is not applicable for the reasons stated in point 8.

    Device Description

    The ECHELON™ 3000 45mm and 60mm Staplers are intended for transection, resection, and/or creation of anastomoses. The instruments have applications in multiple open or minimally invasive general, urologic, thoracic, and pediatric surgical procedures. They can be used with staple line or tissue reinforcement materials. The instruments may also be used for transection and resection of liver parenchyma (hepatic vasculature and biliary structures), pancreas, kidney, and spleen. The ECHELON™ 3000 Staplers are sterile, single-patient use instruments that simultaneously cut and staple tissue. There are six staggered rows of staples, three on either side of the cut line.

    The devices are available in two different configurations (ECHELON™ 3000 45mm Staplers and ECHELON™ 3000 60mm Staplers) and three different shaft lengths (Compact, Standard, and Long). The device utilizes battery power to fire the device. The instruments are packaged with a primary lithium battery pack that must be installed prior to use.

The instrument lock-out feature is designed to prevent a used or improperly installed reload from being re-fired or an instrument from being fired without a reload.

    AI/ML Overview

    This document is a 510(k) Premarket Notification from the FDA regarding surgical staplers. It does not contain the kind of detailed study information (acceptance criteria, specific performance metrics, sample sizes, expert qualifications, ground truth methodology, MRMC studies, etc.) that would typically be found in a clinical study report or a more comprehensive technical document supporting an AI/software as medical device (SaMD) submission.

    The document primarily focuses on demonstrating substantial equivalence to existing predicate devices (ECHELON 3000 45mm and 60mm Staplers, K213633). The changes described are primarily dimensional and material changes to a non-patient contacting component (the "shifter plate") within an already cleared device.

    Therefore, for your request, I cannot extract specific acceptance criteria for AI performance, details on test set data provenance, expert adjudication methods, MRMC studies, or training set details because this submission is about a mechanical surgical stapler, not an AI/software device.

    The "Non-Clinical and/or Clinical Tests Summary & Conclusions" section explicitly states:

    • "The premarket submission did not rely on the assessment of clinical performance data to demonstrate device performance and equivalence."
    • Performance testing focused on:
      • "Closure Force during Device shifting testing... against the predicate Design Requirement using success criteria with the original validated Test Method."
      • "Side by side component level testing... to confirm equivalent or better strength and wear properties" (e.g., Component withstand strength, Pinning for Device assembly, and cyclic wear during Device closure).

    In summary, the provided text does not contain the information requested regarding acceptance criteria and a study proving device performance in the context of AI/SaMD. It describes a traditional medical device submission for mechanical changes to a surgical stapler.

    Intended Use

    The ENSEAL X1 Curved Jaw and ENSEAL X1 Straight Jaw Tissue Sealers are bipolar electrosurgical instruments for use with an electrosurgical generator. They are indicated for use during open or laparoscopic surgery.

    Indications for use include open and laparoscopic general surgical procedures (including bowel resections, gynecology, gastric, urologic and thoracic surgical procedures) where vessel ligation (sealing and cutting), division of lymphatics, tissue grasping and dissection is performed. The devices can be used on vessels and vascular bundles up to and including 7 mm in diameter.

    Device Description

    The ENSEAL™ X1 Curved and Straight Jaw Tissue Sealers are intended to cut and seal vessels, and to cut, grasp, and dissect tissue during surgery.

    The ENSEAL™ X1 Curved and Straight Jaw Tissue Sealers are sterile, single-patient-use surgical instruments used to coagulate and transect vessels up to and including 7 mm in diameter, tissue, and/or vascular bundles. These devices are for soft tissue only. The instrument consists of a grip housing assembly, a rotating shaft, a moveable jaw, and a knife. The instrument shaft can be rotated 360° to facilitate visualization and enable easy access to targeted tissue. The jaws are in a normally-opened position and can be partially or fully closed by squeezing the closing handle. The jaws are designed for grasping and holding targeted tissue when clamped. The ENSEAL™ X1 Curved and Straight JawTissue Sealers have separate seal and cut capabilities. The lower jaw of the ENSEAL™ X1 Curved and Straight Jaw Tissue Sealers can be used in the open or closed position to deliver energy based on the electrode configuration and jaw design. Bipolar energy is delivered when the SEAL button or the MIN foot pedal is pressed. Pressing the CUT button advances the knife the length of the jaws to cut the targeted tissue. The power cord is permanently attached to the device and connects the instrument to the generator. The ENSEAL™ X 1 Curved and Straight Jaw Tissue Sealer instruments are designed for use exclusively with the Ethicon Generator G11(GEN11). software version 2016-1 or later, or other compatible Ethicon generators. Refer to the Ethicon Generator's Manual for more information.

    AI/ML Overview

    The provided text is a 510(k) summary for the ENSEAL X1 Curved and Straight Jaw Tissue Sealers. It details the device's indications for use, comparison to predicate devices, and performance data. However, it does not describe an AI/device performance study with the detailed acceptance criteria and study design requested in the prompt.

    Specifically, the document states:

    • "Bench Performance data was not included as part of this premarket notification. There is no change in the technological characteristics between the subject device ENSEAL™ X1 Curved and Straight Jaw Tissue Sealers and cleared predicates; Curved Jaw Tissue Sealer (K201066) and Straight Jaw Tissue Sealer (K201696)."
    • "An acute animal study was conducted that evaluated the performance of ENSEAL X1 Curved and Straight Jaw Tissue Sealers in gastric procedures."

    This indicates that the submission relies on the substantial equivalence to predicate devices, and the animal study is for performance evaluation in a specific procedural context, not for evaluating an AI algorithm against a test set with ground truth established by experts.

    Therefore, I cannot extract the information requested in points 1-9 of your prompt, as the provided text does not contain details about an AI-based device performance study, acceptance criteria for an AI algorithm, or details related to ground truth establishment by experts for AI evaluation.

    Intended Use

    The ECHELON LINEAR™ Cutters have application in gastrointestinal, thoracic, and pediatric surgery for transection, resection, and the creation of anastomoses.

    Device Description

    The ECHELON LINEAR™ Cutter delivers two, double-staggered rows of staples while simultaneously dividing the tissue between rows. The instrument has a safety lockout feature that is designed to prevent firing if either no reload or a used reload is installed. An unclamp lockout feature prevents knife exposure by allowing the instrument to open only when the Firing Knob is in the home position. A clamp lockout feature prevents closure of the jaws when the knife is not in the home position. A Staple Retaining Cap on the reload protects the staple leg points during shipping and transportation.

    This device may be used on the general population for routine wound closure via stapling.

    The 60 mm reload creates a 61 mm staple line and cuts tissue approximately 52 mm beyond the tissue stop.

    The 80 mm reload creates an 81 mm staple line and cuts tissue approximately 72 mm beyond the tissue stop.

    The 100 mm reload creates a 101 mm staple line and cuts tissue approximately 92 mm beyond the tissue stop.

    The instruments are shipped without a reload and must be loaded prior to use. The instrument may be loaded eight times for a maximum of eight firings per instrument during a single procedure.

    AI/ML Overview

    This document describes the premarket notification (510(k)) for the ECHELON LINEAR™ Cutters, demonstrating its substantial equivalence to a predicate device. As such, the "acceptance criteria" and "device performance" in this context refer to the results of bench and animal testing that demonstrate the new device functions as intended and is safe and effective when compared to existing, legally marketed devices.

    It's important to note that this is a 510(k) summary, not a detailed study report. Therefore, some granular details like exact sample sizes for each specific test might not be explicitly stated, but the types of tests and the overall conclusion are provided. The document specifically states that no clinical studies were performed.

    Here's a breakdown of the requested information based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    For a 510(k) submission, "acceptance criteria" for performance data typically refers to demonstrating that the new device performs comparably to the predicate device and meets functional requirements (e.g., staple formation, strength, operational forces). The document states that the testing demonstrated substantial equivalence, implying the "acceptance criteria" were met by the "reported device performance."

    Acceptance Criteria (Implied)Reported Device Performance
    Bench Testing:
    Device Stapling Performance (Formed Staple Height (FSH), Staple Form Quality (SFQ), Staple Line Integrity (SLI)) comparable to predicate.Performance demonstrated as substantially equivalent to the predicate device. Specific quantitative values for each performance metric are not provided in this summary but would have been demonstrated to be within acceptable ranges or comparable to the predicate.
    Device Functional Requirements (Force to Close/Clamping Force, Force to Fire, Force to Couple/Decouple Device Halves, Force to Press Clamp Release Button, Human Factor Report) met.Functional requirements were met.

    2. Sample Sizes Used for the Test Set and Data Provenance

    • Sample Sizes for Test Set (Bench and Animal Testing): The specific sample sizes for each bench test (e.g., number of staples tested for FSH, SFQ, SLI; number of devices for force measurements) and for the animal studies are not explicitly stated in this 510(k) summary. These details would be contained in the full submission, but not in this public summary.
    • Data Provenance: Not explicitly stated. For bench and animal testing typically conducted internally or by contract research organizations, the country of origin is usually the manufacturer's location or the location of the testing facility. The data would be considered prospective as it's generated for the purpose of the submission.

    3. Number of Experts Used to Establish Ground Truth and Qualifications

    This information is not applicable/not provided in this context. For a device like a surgical stapler, "ground truth" is established through engineering specifications, scientific principles, and established methods for evaluating device performance (e.g., measuring staple dimensions, tensile strength, in-vivo tissue response). There isn't a subjective "expert read" or "adjudication" in the same way there would be for an AI diagnostic algorithm.

    4. Adjudication Method for the Test Set

    This information is not applicable/not provided. As explained above, for a mechanical device, performance is evaluated against objective, measurable criteria, not subjective expert opinion requiring adjudication.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No, an MRMC comparative effectiveness study was not done. The document explicitly states: "The premarket submission did not rely on the assessment of clinical performance data to demonstrate device performance and equivalence." This device is not an AI diagnostic tool and does not involve human readers for interpretation.

    6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

    No, a standalone algorithm study was not done. This device is a mechanical surgical stapler, not an AI algorithm.

    7. Type of Ground Truth Used

    The "ground truth" for this device is based on:

    • Engineering specifications and design parameters: For bench testing (e.g., desired staple height, cutting length, force requirements).
    • Biomechanical principles: For staple line strength and integrity.
    • Physiological outcomes: For animal testing (e.g., hemostasis, tissue healing).
    • Comparison to predicate device performance: The core of a 510(k) is demonstrating substantial equivalence to a legally marketed predicate device, implying that the predicate's established safe and effective performance serves as a benchmark for the new device.

    8. Sample Size for the Training Set

    This information is not applicable/not provided. This is a mechanical device, not an AI/ML algorithm that requires a "training set."

    9. How the Ground Truth for the Training Set Was Established

    This information is not applicable/not provided. As above, there is no "training set" for a mechanical device.

    Intended Use

    The HARMONIC 700, 5 mm Diameter Shears with Advanced Hemostasis are indicated for soft tissue incisions when bleeding control and minimal thermal injury are desired. The instruments can be used as an adjunct to or substitute for electrosurgery, lasers and steel scalpels in general, pediatric, gynecologic, urologic, thoracic procedures, and sealing and transection of lymphatic vessels. The instruments allow for the coagulation of vessels up to and including 7 mm in diameter, using the Advanced Hemostasis hand control button.

    Device Description

    The HARMONIC 700, 5 mm Diameter Shears with Advanced Hemostasis are intended for soft tissue incisions when bleeding control and minimal thermal injury are desired. The instruments are sterile, single-patient-use instruments consisting of an ergonomic grip housing assembly with hand control buttons (MIN for minimum power level, MAX for maximum power level, and Advanced Hemostasis for large vessel sealing). An integrated audible and tactile mechanism in the grip housing indicates full trigger closure. The instruments have a clamp arm and coated curved blade that are designed to work through a 5 mm trocar, through a 5 mm reducer cap in a larger diameter trocar, or through an incision without the use of a trocar. The instrument shafts can be rotated 360° to facilitate visualization and access to targeted tissue. The three dashes on the instrument are intended to represent relative vessel size. The MAX button is typically used for smaller vessels where cutting speed is the fastest. The MIN button is typically used in slightly larger vessels and has reduced cutting speed. It is indicated for vessels up to 5 mm in size. The Advanced Hemostasis button is designed for larger vessels and is indicated for vessels up to 7 mm in size. In this mode, cutting speed is further reduced and hemostasis is maximized. This design is common to both subject and predicate devices and has been evaluated by FDA in K132612 (predicate device), K160752 (HARMONIC HD1000i), and K200841 (HARMONIC 1100). The instruments utilize Adaptive Tissue Technology. This provides the generator with the ability to identify and monitor the instrument during use, which enables the generator to modulate and adjust its power output as well as provide audible feedback to the user as appropriate. The HARMONIC 700, 5 mm Diameter Shears with Advanced Hemostasis are designed for use exclusively with the Generator G11 (GEN11) software version 2018-1 or later, last cleared under K200841 on 11 May 2020.

    2. Sample Size and Data Provenance for Test Set (Preclinical Studies)

    • Acute Animal Testing: Performed in three acute porcine studies. The document does not specify the exact number of animals or vessels tested within these studies, but it mentions evaluating "arteries, veins, and pedicles of various sizes."
      • Data Provenance: Porcine (animal) models. This is a form of prospective data collection for preclinical evaluation.
    • Chronic Animal Testing: Performed in a survival study. The document does not specify the exact number of animals or vessels tested.
      • Data Provenance: Animal (survival) model. This is a form of prospective data collection for preclinical evaluation.

    3. Number of Experts and Qualifications for Ground Truth of Test Set

    The document does not mention the use of human experts to establish ground truth for the test set in the context of the preclinical (animal) studies. The evaluation metrics (e.g., vessel burst pressure, thermal spread, intra-operative tissue effects, post-operative performance) are typically measured objectively by research staff or specific equipment.

    4. Adjudication Method for Test Set

    Not applicable, as ground truth for the preclinical studies was based on objective measurements rather than human reader interpretation requiring adjudication.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The document explicitly states: "This premarket notification does not rely on human clinical trial data to demonstrate substantial equivalence." The comparison is between the subject device and a predicate device through bench and animal testing.

    6. Standalone (Algorithm Only) Performance

    Not applicable. This device is a surgical instrument, not an AI or algorithm-based diagnostic/screening tool. The "Adaptive Tissue Technology" mentioned gives the generator "the ability to identify and monitor the instrument during use, which enables the generator to modulate and adjust its power output as well as provide audible feedback," which is an integrated system feature, not a standalone algorithm being evaluated for performance against a ground truth.

    7. Type of Ground Truth Used (for preclinical studies)

    The ground truth for the preclinical studies was based on objective biological and mechanical outcomes measured in animal models (porcine).

    • Acute Studies: Evaluation of "intra-operative tissues effects," "thermal spread," and the ability to "transected and sealed" vessels and pedicles.
    • Chronic Studies: Evaluation of the long-term performance of "transected and sealed" blood vessels and blood vessel pedicles in a survival setting.
    • Bench Testing: Direct physical measurements such as Tissue Pad Life, Tissue Pad Removal Force, Instrument Grasping Force, Sealed Vessel Burst Pressure, and objective measurements of thermal spread.

    8. Sample Size for the Training Set

    Not applicable. This device is a physical surgical instrument and does not involve AI/machine learning models that require a separate "training set" of data in the conventional sense for performance evaluation in this 510(k) submission. The "Adaptive Tissue Technology" is a functional design feature, not a trainable AI model in the context of this submission.

    9. How the Ground Truth for the Training Set Was Established

    Not applicable, as there is no "training set" as understood in AI/machine learning contexts for this device submission.

    AI/ML Overview

    The provided information is for the ECHELON ENDOPATH Staple Line Reinforcement device. This submission is a 510(k) premarket notification, indicating that the device is claiming substantial equivalence to a predicate device, rather than presenting novel clinical study data for a new device. The "study" mentioned mainly refers to bench testing for compatibility.

    Here's a breakdown of the requested information based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance CriteriaReported Device Performance
    All bench studies passed the criteria for success.
    Device Compatibility with Stapler and Reloads (including Intuitive Surgical SureForm™ 60 mm Blue, Green, and Black Reloads and SureForm™ 60 mm Stapler)Passed
    Staple Form QualityPassed
    Staple Line IntegrityPassed
    Manipulation of device on tissuePassed
    Buttress security on Surgical Stapler and ReloadPassed
    Release ForcePassed
    Shear ForcePassed
    Usability TestingPassed

    Note: The document states "All bench studies passed the criteria for success," but it does not explicitly list the specific numerical acceptance criteria (e.g., a minimum force in Newtons for shear force) for each test. Instead, it confirms that the device met whatever criteria were predefined for these tests.

    2. Sample Size Used for the Test Set and Data Provenance

    The document only mentions "bench testing." It does not specify sample sizes for individual tests. The data provenance is laboratory/bench testing, not human or animal data. Therefore, details like country of origin for data or retrospective/prospective do not apply in the context of this bench study.

    3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

    Not applicable. This was a bench study, not an expert-driven clinical evaluation. The "ground truth" would be the engineering specifications and performance thresholds set for the device's mechanical properties, not expert consensus on medical images or clinical outcomes.

    4. Adjudication Method for the Test Set

    Not applicable. This was a bench study with objective measurements, not a test involving human interpretation requiring adjudication.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance

    No a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done. This device is a mechanical staple line reinforcement, not an AI-powered diagnostic or assistive tool.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

    Not applicable. This device is a passive mechanical component, not an algorithm.

    7. The Type of Ground Truth Used

    The ground truth for the bench testing would be established by the engineering and design specifications for the device's mechanical properties and compatibility requirements with the staplers. This typically involves objective physical measurements and established test methods, not expert consensus, pathology, or outcomes data in the traditional sense of a clinical study.

    8. The Sample Size for the Training Set

    Not applicable. There is no information in the document about a "training set" as this is a mechanical device, not an AI or machine learning model.

    9. How the Ground Truth for the Training Set Was Established

    Not applicable, as there is no training set.

    Intended Use

    The ECHELON FLEX™, ECHELON™ 3000, and ECHELON ENDOPATH™ families of staplers and reloads are intended for transection, and/or creation of anastomoses. The instruments have application in multiple open or minimally invasive general, urologic, thoracic, and pediatric surgical procedures. They can be used with staple line or tissue reinforcement materials. The instruments may also be used for transection of liver parenchyma (hepatic vasculature and biliary structures), pancreas, kidney and spleen.

    Device Description

    The ECHELONTM 3000 45 mm and 60 mm Staplers are sterile, single-patient-use instruments that simultaneously cut and staple tissue. There are six staggered rows of staples, three on either side of the cut line.

    The ECHELON™ 3000 45 mm Staplers have a staple line that is approximately 45 mm long and a cut line that is approximately 42 mm long.

    The ECHELON™ 3000 60 mm Staplers have a staple line that is approximately 60 mm long and a cut line that is approximately 57 mm long.

    The shaft can rotate freely in both directions and an articulation mechanism enables the distal portion of the shaft to pivot to facilitate lateral access to the operative site.

    The instruments are packaged with a primary lithium battery pack that must be installed prior to use. There are specific requirements for disposing of the battery pack. Refer to the Battery Pack Disposal section.

    The instruments are packaged without a reload and must be loaded prior to use. A staple retaining cap on the reload protects the staple leg points during shipping and transportation. The instruments' lock-out feature is designed to prevent a used or improperly installed reload from being refired or an instrument from being fired without a reload.

    AI/ML Overview

    The provided text is a 510(k) summary for the ECHELON™ 3000 Surgical Stapler. It outlines the device description, indications for use, comparison to predicate devices, and performance data used to demonstrate substantial equivalence. However, it does not contain the detailed information required to answer all parts of your request, specifically regarding acceptance criteria and the specifics of a study proving the device meets those criteria for an AI/algorithm-based medical device.

    The document discusses performance data for a surgical stapler, which is a mechanical device, not an AI/algorithm-based diagnostic or therapeutic tool. Therefore, the types of "acceptance criteria" and "studies" will differ significantly from those for an AI system.

    Here's how the information provided relates to your request, and where there are gaps due to the nature of the device:

    Regarding the Surgical Stapler (as described in the document):

    • Acceptance Criteria and Reported Performance: The document lists various bench testing criteria (Formed Staple Height (FSH), Staple Line Integrity (SLI), Force to Close, Staple Line Visual Analysis, Staple Line Strength) and animal testing (Acute Hemostasis evaluation, Tissue Healing response, Survival Study). For a 510(k), the "acceptance criteria" are generally that the device performs comparably to a predicate device and does not raise new questions of safety or effectiveness. The reported performance is that these tests "demonstrate that the subject device performs substantially equivalent to the predicate device and does not raise new questions of safety and effectiveness." However, specific numerical acceptance criteria (e.g., FSH must be within X range) and the exact numerical performance results are not provided in this summary. This level of detail is typically found in the full 510(k) submission, not the public summary.

      Given that this is a mechanical device, not an AI, a table like you requested would list mechanical properties and their measured values against predefined acceptable ranges derived from the predicate device or engineering specifications.

    • Sample Size: The document mentions "bench testing" and "animal testing" but does not specify the sample sizes used for these tests.

    • Data Provenance: Not specified for the bench or animal testing.

    • Number of Experts/Qualifications/Adjudication Method for Test Set: Not applicable in the context of this device's testing. These are relevant for AI systems relying on expert ground truth.

    • MRMC Comparative Effectiveness Study: Not applicable. This is a study design for evaluating the impact of AI on human reader performance. This device is a mechanical stapler.

    • Standalone Performance: The "bench testing" and "animal testing" can be considered "standalone" performance testing for a mechanical device, as it evaluates the device's physical properties and function without human intervention beyond operation.

    • Type of Ground Truth: For a mechanical device like a stapler, "ground truth" equates to established engineering specifications, mechanical properties (e.g., staple height, tensile strength), and biological outcomes (e.g., hemostasis, healing) validated through standard scientific and engineering practices. It's not "expert consensus" on an image, but rather measurable physical and biological parameters.

    • Sample Size for Training Set: Not applicable. This device is not an AI/machine learning model that undergoes a "training set" process.

    • How Ground Truth for Training Set was Established: Not applicable for the same reason.

    If the request was hypothetically for an AI-based medical device, and we were to invent the details based on common FDA expectations for AI/ML:

    Let's imagine this document was for an AI-powered diagnostic tool. Here's what such a response would include, creating hypothetical details where the provided document has gaps:

    Reader Efficiency (Time per case)≤ Time per case (unaided)-15% (faster)

    2. Sample Size Used for the Test Set and Data Provenance

    • Sample Size: 500 cases (e.g., 250 positive, 250 negative for the condition).
    • Data Provenance:
      • Country of Origin: Multi-site, primarily from hospitals in the United States and Europe.
      • Retrospective/Prospective: Primarily retrospective data collected from institutional archives. A small subset (50 cases) was prospectively collected to ensure generalizability.

    3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

    • Number of Experts: 3 independent expert readers.
    • Qualifications: All were board-certified radiologists with at least 10 years of experience in diagnosing the target condition. Two had fellowship training in the relevant sub-specialty.

    4. Adjudication Method for the Test Set

    • Method: 2+1 adjudication. Initial reads by two independent expert radiologists. In cases of disagreement, a third, senior-level radiologist (the "tie-breaker") reviewed the case and the initial reads to make a final ground truth determination.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    • Yes, an MRMC study was performed.
    • Effect Size: The study demonstrated a statistically significant improvement in human reader performance when assisted by the AI.
      • Sensitivity: Human readers' sensitivity improved by an average of 6.1 percentage points (e.g., from 82% unaided to 88.1% AI-assisted, p

The fundamental operational principle of converting electrical energy to mechanical motion for the instrument blade remains unchanged.
    Device modifications (connector, software compatibility, EEPROM, cable design, cable components, protective end cap) do not introduce risks or degrade safety/effectiveness.Confirmed: Risk analyses for each device modification were provided and concluded that the risk profile of the new devices has not changed. Verification testing, Biocompatibility evaluation, and Electrical testing were conducted to confirm that the modifications do not raise new issues of safety or effectiveness.

    Study Information:

    1. Sample size used for the test set and the data provenance:

      • The document does not specify a distinct "test set" in the context of a clinical study or a separate performance evaluation on patient data.
      • The evaluation primarily involved verification testing, biocompatibility evaluation, and electrical testing on the modified devices. These tests would have been performed on a sample of the manufactured devices, but the specific number of units tested is not provided.
      • The data provenance is implied to be from laboratory and engineering testing of the devices themselves, rather than clinical patient data.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • No information is provided about experts used to establish ground truth. This is not a clinical study involving interpretation of medical images or patient outcomes. The evaluation is focused on engineering and performance validation against internal specifications and regulatory standards.
    3. Adjudication method for the test set:

      • No adjudication method is described, as the studies conducted are not clinical studies requiring expert consensus on ground truth. The evaluation likely involved objective measurements and comparisons against established engineering specifications and regulatory standards.
    4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

      • No. This document describes a 510(k) submission for surgical hand pieces, not an AI-powered diagnostic device. Therefore, an MRMC study comparing human readers with AI assistance is not applicable and was not conducted.
    5. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

      • Not applicable. This device is a surgical instrument and does not involve an algorithm with standalone performance.
    6. The type of ground truth used:

      • The ground truth in this context is based on engineering specifications, regulatory standards (e.g., ISO 10993-1 for biocompatibility), and the established safety and effectiveness profile of the predicate devices. The aim was to ensure that the modified devices adhered to these objective standards and did not deviate from the performance of the predicate.
    7. The sample size for the training set:

      • Not applicable. This is not a machine learning or AI device that requires a training set. The "training" here refers to the design and manufacturing processes guided by established engineering principles and prior device knowledge.
    8. How the ground truth for the training set was established:

      • Not applicable. As this is not an AI/ML device, there isn't a training set in that sense. The "ground truth" for the device's design and manufacturing is based on established engineering principles, material science, and regulatory requirements, which are developed through years of research, testing, and clinical experience with similar medical devices.
