    Intended Use

    The RITA Medical Systems UniBlate Electrosurgical Device is intended to coagulate tissue during percutaneous, laparoscopic, and intraoperative surgical procedures.

    Device Description

    The UniBlate Electrosurgical Device is a monopolar radiofrequency (RF) device that consists of a variably insulated electrode. The instrument has an attached electrical cable and infusion tubing set which connects the device directly to the RITA Medical 1500X RF generator and the IntelliFlow peristaltic pump respectively. The electrical cable provides RF energy and temperature feedback to the generator and the pump infuses normal saline through the infusion tubing set. The UniBlate Electrosurgical Device is a single use device.

    AI/ML Overview

    The provided text describes a 510(k) summary for the UniBlate Electrosurgical Device. This regulatory submission primarily focuses on demonstrating substantial equivalence to predicate devices through performance testing, rather than establishing clinical efficacy through a detailed study with specific acceptance criteria as one might find for a novel therapeutic device.

    Therefore, the requested information regarding "acceptance criteria" based on a study of clinical performance, "sample size for the test set," "number of experts," "adjudication method," "MRMC comparative effectiveness study," "standalone performance," "type of ground truth," and "sample size for the training set" is not explicitly available within the provided text.

    The document indicates that "Performance testing was done to ensure that the UniBlate Device functions as intended and meets design specifications." However, it does not detail these design specifications as specific quantitative acceptance criteria or report device performance against them in a table format. The primary goal of this 510(k) submission is to show that the device is "substantially equivalent to the predicate device, and meets safety and effectiveness criteria" through these performance tests, which are not described in detail.

    Here's what can be extracted and inferred from the text:

    1. Table of Acceptance Criteria and Reported Device Performance

    Not explicitly provided in the document. The text states: "Performance testing was done to ensure that the UniBlate Device functions as intended and meets design specifications. Sufficient data was obtained to show that the device is substantially equivalent to the predicate device, and meets safety and effectiveness criteria." This implies that internal acceptance criteria were met, but they are not listed, nor are specific performance metrics reported against them. The focus is on substantial equivalence to predicate devices (StarBurst XLi and Cool-Tip RF System) in terms of principles of operation, construction, and intended use.

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

    Not explicitly provided in the document. The text mentions "Performance testing" but does not detail the nature, sample size, or provenance (country of origin, retrospective/prospective) of any clinical or technical test sets used for evaluating the device against its "design specifications."

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

    Not applicable/provided. The document describes performance testing for device functionality and design specifications, not a study requiring expert-established ground truth for clinical outcomes or diagnostic accuracy.

    4. Adjudication Method for the Test Set

    Not applicable/provided. No information on an adjudication method is discussed, as the document focuses on technical performance and substantial equivalence.

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

    No. The document does not mention an MRMC comparative effectiveness study. The context is a device for tissue coagulation, not a diagnostic imaging device where such studies are common.

    6. Standalone (Algorithm Only) Performance Study

    Not applicable. The UniBlate device is an electrosurgical device, not an algorithm. The concept of "standalone performance" in this context would relate to the device operating as designed, independent of human intervention in its function, which is implicitly what "Performance testing was done to ensure that the UniBlate Device functions as intended and meets design specifications" refers to. However, this is not detailed as a separate study.

    7. Type of Ground Truth Used

    Device-specific test parameters/design specifications, implicitly. For an electrosurgical device, "ground truth" for performance testing would typically refer to established engineering and safety standards, as well as the ability to achieve defined tissue coagulation parameters (e.g., lesion size, temperature profiles) in a controlled environment, demonstrating it functions "as intended." However, these specific "ground truths" (e.g., measurements of coagulation zone, power output, temperature feedback accuracy) are not detailed in the summary. The overarching "ground truth" for the 510(k) is substantial equivalence to legally marketed predicate devices.

    8. Sample Size for the Training Set

    Not applicable/provided. This device is hardware and does not involve AI or machine learning that would require a "training set."

    9. How Ground Truth for the Training Set Was Established

    Not applicable. As above, no training set is discussed or implied.

The catheters all contain radiopacifiers, and depth markings.

    The LifeGuard safety infusion set is a port access needle set with an integrated proprietary safety feature to prevent re-bound injury. The safety infusion set includes a huber needle, a winged housing, non-DEHP PVC extension legs, and a luer standard connector.

    AI/ML Overview

    This document describes the non-clinical performance data for the Vortex® CT Port Access System and LifeGuard® Safety Infusion Set, which is a medical device for vascular access and power injection of contrast media.

    Here's the information requested:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not provide specific "reported device performance" values for each test, but rather indicates that the tests were performed to establish substantial equivalence, safety, and effectiveness. The "Required Results" column from the provided table serves as the acceptance criteria.

    Test DescriptionSample SizeRequired Results (Acceptance Criteria)Reported Device Performance

    Puncture Life2Establish label claim for largest needle likely to be used during power injectionNot explicitly stated; "non-clinical tests demonstrate that the device is as safe, as effective" implies compliance.

    The study concludes that "The non-clinical tests demonstrate that the device is as safe, as effective for the modified intended use." This statement implies that the device met all the required results set as acceptance criteria for the non-clinical tests.

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

    • Test Set Sample Sizes:
      • Sterilization exposure: All
      • Physiological exposure: All
      • Power injection Performance Test: 18
      • Simulated Power Injection: 30
      • Dynamic Failure Test: 18
      • Static Burst Test: 18
      • Life Cycle Power Injection Test: 10
      • Cyclic testing: 30, 10 cycles per port
      • Port Patency Verification: 5
      • Port Occlusion Test: 10
      • Puncture Life: 2
    • Data Provenance: The data is from non-clinical testing. There is no mention of country of origin for the data (as it's laboratory-based testing, not human patient data) and it is inherently prospective as it involves conducting specific tests on the devices.

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

    Not applicable. This is a submission for a physical medical device (Vortex® CT Port Access System and LifeGuard® Safety Infusion Set) and the testing performed is non-clinical/pre-clinical (laboratory-based physical and performance testing), not involving human interpretative tasks or diagnostic assessment. Therefore, no experts were used to establish ground truth in the context of diagnostic accuracy, and no qualifications of such experts are relevant.

    4. Adjudication Method for the Test Set

    Not applicable, for the same reasons as point 3. The tests are objective physical and performance measurements with defined pass/fail criteria, not subjective assessments requiring 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

    Not applicable. This device is a physical medical port and infusion set, not an AI or imaging diagnostic tool. Therefore, MRMC studies and AI assistance are not relevant to its evaluation.

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

    Not applicable. This device is a physical medical product, not an algorithm.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

    The "ground truth" for the non-clinical tests is based on pre-defined engineering specifications and performance requirements. These are objective, measurable outcomes (e.g., "no bursts, leaks, / plastic deformations allowed," "meet expected flow rate and pressure withstand requirements," "withstand 10 cycles").

    8. The sample size for the training set

    Not applicable. Since this is a physical medical device and not an AI/machine learning model, there is no "training set."

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

    Not applicable, for the same reason as point 8.

    Intended Use

    The OmniPICCPI Peripherally Inserted Central Catheter is indicated for use in attaining short and long term vascular access for administration of medications, parenteral nutrition, IV fluids, blood products or blood withdrawal. The OmniPICCPI is indicated for power injection of contrast media at a maximum recommended infusion rate of 3ml/sec and maximum pressure or pounds per square inch (psi) of 300 psi.

    Device Description

    The Peripherally Inserted Central Catheter (OmmiPICC P.I.) kit includes a catheter and introduction components. The catheter is a percutaneous central venous catheter inserted peripherally. The catheter is comprised of radiopaque polyurethane tubing. The catheter is attached to an injection molded polyurethane hub with extension leg(s) for access via a luer lock device. Each product is packaged in a sterile tray with appropriately sized introducer components. This PICC product line includes externally communicating central venous catheters of 60 cm that is trimmable from the distal end with a single 4 Fr single and 5 Fr dual lumen configurations. These are tested to withstand power injection of 3ml/sec (4 Fr Single) to 5 ml/sec at a maximum power injection setting of 300 psi.

    AI/ML Overview

    The provided document is a 510(k) premarket notification for the OmniPICC P.I. (Peripherally Inserted Central Catheter). This type of submission is for medical devices and focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than conducting a full clinical trial to prove safety and effectiveness from scratch. Therefore, the information typically requested in your prompt regarding acceptance criteria, specific study designs (like MRMC), and detailed ground truth establishment for AI/algorithm-based devices is not present in this document because it pertains to a different type of device (a physical medical catheter) and regulatory pathway.

    The document describes the device, its intended use, and its indications for use, highlighting its capability for power injection. The primary "study" involved is a comparison to a predicate device (Bard PowerPICC™ Catheter) to demonstrate substantial equivalence, rather than a clinical trial assessing performance against specific acceptance criteria in the way an AI diagnostic device would.

    However, I can extract the relevant information that is present in the document. The "device performance" in this context refers to its physical capabilities for power injection, which are stated parameters rather than measured outcomes from a clinical study with a test set.

    Here's the closest representation of the requested information based on the provided text:

    Acceptance Criteria and Reported Device Performance

    The document describes the physical capabilities and new features of the OmniPICC P.I. to justify its substantial equivalence to predicate devices, particularly for power injection. The "acceptance criteria" for the device, in this context, are the specified physical performance limits it is designed to meet for safe and effective use during power injection procedures.

    Acceptance Criteria (Stated Device Capability)Reported Device Performance (as described)
    Maximum recommended infusion rate for 4 Fr single lumen catheter3ml/sec
    Maximum recommended infusion rate for 5 Fr dual lumen catheter5ml/sec
    Maximum pressure for power injection300 psi
    Catheter materialRadiopaque polyurethane tubing
    Configuration4 French single and 5 French dual lumen
    Dwell timeShorter or greater than 30 days
    Identification of power injectability"POWER INJECTABLE" printed on extension legs; "300 PSI" and "3ml/sec" (or "5ml/sec") printed on ID inserts.

    Study Details (Based on Substantial Equivalence Justification)

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

    • Sample Size: Not applicable in the context of a clinical test set for AI. The "test" for this device involved comparing its physical and material characteristics, intended use, and indications for use against predicate devices. The document does not describe a clinical trial with a "test set" of patients or data.
    • Data Provenance: Not applicable. The justification is based on design specifications and material properties, rather than patient data.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience):

    • Not applicable. Ground truth as typically understood for AI algorithms (e.g., expert consensus on an image) is not relevant for this medical device submission. The "ground truth" for a substantial equivalence determination is the performance and safety profile of the predicate device and the engineering specifications of the new device.

    4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

    • Not applicable. No clinical test set requiring adjudication of findings is described.

    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:

    • Not applicable. This is not an AI/software device, therefore MRMC studies are irrelevant to this submission.

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

    • Not applicable. This is a physical medical device, not an algorithm.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

    • For the purpose of a 510(k) for a physical medical catheter, the "ground truth" is established by a combination of:
      • Predicate Device Performance: The safety and effectiveness data and established performance of legally marketed predicate devices (OmniPICC PI™ Catheter, PowerPICC™ Catheter).
      • Engineering Specifications and Material Testing: The inherent physical properties, design, and manufacturing standards of the OmniPICC P.I. catheter, including its ability to withstand specified pressures and flow rates for power injection.
      • Regulatory Standards: Compliance with relevant FDA regulations (e.g., 21 CFR 880.5970).

    8. The sample size for the training set:

    • Not applicable. No training set for an algorithm is described.

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

    • Not applicable. No training set for an algorithm is described.

    Summary of the "Study" (510(k) Substantial Equivalence):

    The document serves as a premarket notification (510(k)) to the FDA. The "study" described is a demonstration of substantial equivalence to previously cleared predicate devices (K051102 for OmniPICC PITM Catheter and K033389, K050931, K051672, & K051991 for PowerPICCTM Catheter by Bard Access Systems, Inc.).

    Key points of this "study" are:

    • Intended Use and Fundamental Scientific Technology: The OmniPICC P.I. is stated to be identical to its predicate device (Bard PowerPICC™) in these aspects.
    • Configuration, Dimensions, and Materials: The two devices are stated to be substantially similar in these aspects. The 510(k) specifically aims to add new product codes in 4 French single and 5 French dual lumen sizes, which are within the scope of predicate devices' capabilities.
    • Performance Claim: The device has been tested (implicitly, through engineering and design validation) to withstand power injection of 3ml/sec (4 Fr Single) to 5 ml/sec (5 Fr dual lumen) at a maximum power injection setting of 300 psi. This is a design specification intended to demonstrate equivalency or improvement upon predicate devices for similar power injection capabilities.

    This type of submission does not involve clinical trials with human subjects or a statistical analysis of diagnostic accuracy that would be typical for an AI-powered device. Instead, it relies on a comparison of technical specifications, intended use, and materials to establish that the new device is as safe and effective as a device already on the market.

    Intended Use

    The OmniPICC P.I. is intended to be used by medical professionals in patients who require either acute or long-term (chronic) peripheral central venous access for the infusion of medications, nutritional or other parenteral solutions, or blood products, and for the withdrawal of blood samples.

    The OmniPICCPI Peripherally Inserted Central Catheter is indicated for use in attaining short and long term vascular access for administrations, parenteral nutrition, IV fluids, blood products or blood withdrawal. The catheter may be inserted via the basilic, cephalic and medial veins of the upper extremity. The catheter is intended for implantation dwell time of shorter or greater than 30 days. The maximum recommended infusion rate is 5ml/sec. The maximum pressure or pounds per square inch (psi) of the power injector utilized should not exceed 300 psi.

    The OmniPICCPI is indicated for power injection of contrast media at a maximum recommended infusion rate of 5ml/sec and maximum pressure or pounds per square inch (psi) of 300 psi.

    Device Description

    The Peripherally Inserted Central Catheter (OmniPICC P.I.) kit includes a catheter and introduction components. The catheter is a percutaneous catheter inserted peripherally. The catheter is comprised of radiopaque polyurethane tubing. The catheter is attached to an injection molded polyurethane hub with extension leg(s) for access via a luer lock device. Each product is packaged in a sterile tray with appropriately sized introducer components. This PICC product line includes externally communicating central venous catheters of 60 cm that is trimmable from the distal end with a single 5 Fr lumen configuration. These are tested to withstand power injection of 5 cc/sec at a maximum power injection setting of 300 psi.

    AI/ML Overview

    The provided text is a 510(k) summary for the OmniPICC P.I. (Peripherally Inserted Central Catheter). It focuses on establishing substantial equivalence to a predicate device and does not contain information about acceptance criteria or a study that proves the device meets specific performance criteria through an AI/Machine Learning lens.

    Therefore, I cannot fulfill your request for information regarding:

    • A table of acceptance criteria and reported device performance (in the context of AI/ML).
    • Sample size used for the test set and data provenance.
    • Number of experts used to establish ground truth.
    • Adjudication method for the test set.
    • MRMC comparative effectiveness study, including effect size.
    • Standalone algorithm performance.
    • Type of ground truth used (beyond general clinical indications).
    • Sample size for the training set.
    • How ground truth for the training set was established.

    This document is a regulatory submission for a medical device (a catheter), not an AI/ML product. The "acceptance criteria" discussed in such a document would typically refer to engineering specifications, biocompatibility, sterilization, and mechanical testing, not the performance metrics of an AI model against a ground truth.

    If you have a document describing the validation of an AI/ML medical device, I would be happy to analyze it against your specified criteria.

    Intended Use

    The Vortex® EZ Port Access System is indicated for any patient requiring repeated access of the vascular system or other selected body site, for the delivery of medications, nutritional supplementation, fluids, blood, blood products, and sampling of blood.

    Device Description

    The Vortex® EZ Port Access System is a device comprised of a vascular access port, a catheter, locking mechanism and introduction components. The Vortex® EZ Port is available in a Delrin port body configuration with a self sealing silicone septum designed to maintain integrity after repeated punctures with a non-coring needle.

A pre-attached or a detached/attachable catheter is offered in either polyurethane or silicone models with or without a highly radiopaque tip molded on. The products are packaged in sterile trays with introduction components.

    AI/ML Overview

    The provided text is a 510(k) summary for the Vortex® EZ Port Access System. This type of document focuses on establishing substantial equivalence to a legally marketed predicate device rather than detailing specific acceptance criteria and a study proving those criteria are met for novel device performance.

    Therefore, many of the requested sections (e.g., acceptance criteria table, sample sizes for test/training sets, number and qualifications of experts for ground truth, adjudication methods, MRMC study, standalone performance, type of ground truth used, how ground truth for training set was established) are not applicable or not present in the provided document.

    Here's a breakdown of what can be extracted or inferred based on the provided text, and what cannot:

    1. Table of acceptance criteria and the reported device performance:

    • Not applicable/Not present. The document states, "The Vortex® EZ Port Access System design was evaluated through risk analysis and qualified through design verification testing following established Design Control procedures." However, it does not provide specific acceptance criteria or the reported performance data against those criteria. It relies on substantial equivalence to predicate devices (LifePort® VTX® Access System (K010767) and LifePort® LPS 7013 (K905852)).

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

    • Not applicable/Not present. As this is a 510(k) for a device modification, clinical studies with test sets in the context of AI/imaging are not required or detailed here. The premarket notification focuses on design verification testing, which would involve engineering tests rather than patient data.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • Not applicable/Not present. No ground truth established by experts is mentioned, as this is not an AI/imaging device.

    4. Adjudication method for the test set:

    • Not applicable/Not present. No adjudication method is mentioned.

    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:

    • Not applicable/Not present. This device is a vascular access system, not an AI-assisted diagnostic tool. Therefore, an MRMC study is irrelevant.

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

    • Not applicable/Not present. This is not an algorithm-based device.

    7. The type of ground truth used:

    • Not applicable/Not present. No ground truth in the context of clinical outcomes or pathology is used for this type of device submission. The "ground truth" for a medical device in a 510(k) context often relates to demonstrating that the device performs as intended and is safe and effective when compared to existing legally marketed devices, usually through engineering testing, biocompatibility testing, and sometimes bench or animal studies, not typically through clinical "ground truth" in the AI/diagnostics sense.

    8. The sample size for the training set:

    • Not applicable/Not present. This device is a physical medical device, not an AI model requiring a "training set."

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

    • Not applicable/Not present. As above, no training set or ground truth in this context.

It can read multiple temperature sensors and includes impedance and power monitoring to assist the physician in monitoring and controlling the ablation.
    To use the system, the RF Generator is plugged into the wall outlet via the Power Cord. The electrosurgical device is connected to the RF Generator via the Main Cable. The Dispersive Electrode is placed on the appropriate location of the body and is connected to its port on the RF Generator. Once the system is successfully powered up, the user can set the parameters of the ablation such as the mode of operation, the ablation time, the target temperature, and the power delivery level. With the electrosurgical device placed in the tissue to be ablated and its electrodes deployed, RF power can be turned on. The system parameters are continuously monitored and displayed on the RF Generator. If the measured parameters are outside the acceptable limits, the RF energy delivery automatically stops and a message appears on the liquid crystal display (LCD). The RF energy delivery also automatically ceases once the ablation is completed based on the initial user-defined parameters. RF energy can be stopped at any time by pressing the RF ON/OFF switch.

    AI/ML Overview

    The provided text describes the RITA® Model 1500X Electrosurgical RF Generator and its 510(k) submission. However, it does not contain detailed information regarding acceptance criteria and a study proving the device meets those criteria in the way typically expected for performance claims of AI-driven diagnostic devices (e.g., sensitivity, specificity, AUC).

    Instead, the "Performance Data" section of the 510(k) summary simply states: "The Model 1500X RF Generator is subjected to software validation testing." This implies that the device's performance was evaluated against functional and safety requirements, which are inherent to software validation for medical devices, rather than a clinical effectiveness study with specific diagnostic metrics.

    Given this, I will interpret "acceptance criteria and the study that proves the device meets the acceptance criteria" in the context of general device validation for an electrosurgical generator, focusing on safety and functional performance rather than diagnostic accuracy.

    Here's an attempt to answer your questions based only on the provided text, highlighting the limitations:

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

    Based on the provided text, specific quantitative acceptance criteria for clinical performance (like sensitivity, specificity, etc.) are not mentioned. The performance data section vaguely states "software validation testing," which implies functional and safety criteria were met.

    Since no specific performance metrics are given, I can only infer the general intent which is functioning as described and safely.

    Acceptance Criteria (Inferred from Device Description & General Medical Device Requirements)Reported Device Performance (Inferred from "Software Validation Testing" and 510(k) Clearance)
    Functional Performance:
    Delivers monopolar radiofrequency (RF) energy.Yes, the device is designed to provide monopolar RF energy.
    Delivers up to 250 W of RF power.Yes, it is a 250 W electrosurgical generator.
    Can read multiple temperature sensors.Yes, it can read multiple temperature sensors.
    Includes impedance monitoring.Yes, it includes impedance monitoring.
    Includes power monitoring.Yes, it includes power monitoring.
    Assists physician in monitoring and controlling ablation.Yes, through temperature, impedance, and power monitoring.
    Allows user to set parameters (mode, time, target temperature, power level).Yes, the user can set these parameters.
    Continuously monitors and displays system parameters.Yes, system parameters are continuously monitored and displayed.
    Automatically stops RF energy delivery if measured parameters are outside acceptable limits.Yes, RF energy delivery automatically stops if parameters are outside limits.
    Displays a message on LCD if parameters are outside limits.Yes, a message appears on the LCD.

    Device is safe for intended use.Implied by 510(k) clearance following software validation and general safety testing.
    Device is substantially equivalent to predicate device.Yes, determined by FDA.

    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    The text mentions "software validation testing" but provides no details on what was tested (e.g., number of test cases, specific scenarios, or any clinical data). Therefore, the sample size, data provenance, and whether it was retrospective or prospective are not provided.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

    This information is not provided. As "software validation testing" is mentioned, it likely refers to engineering and quality assurance personnel performing functional tests against specifications, rather than clinical experts establishing ground truth for diagnostic or therapeutic outcomes.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    This information is not provided. Given the nature of "software validation testing" for an electrosurgical generator, clinical adjudication methods would typically not be applicable.

    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 comparative effectiveness study was not mentioned and is not applicable to this device. The RITA Model 1500X is an electrosurgical RF generator, not an AI-assisted diagnostic tool for human readers.

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

    This concept is not applicable to an electrosurgical RF generator. The device delivers energy under physician control. The "software validation testing" would be for the internal algorithms controlling power delivery, monitoring, and safety features, which are inherently "standalone" in their function but always within a human-in-the-loop context for actual patient use.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

    For "software validation testing" of an electrosurgical generator, the "ground truth" would typically be the pre-defined functional specifications and safety requirements of the software and hardware. This is not clinical ground truth (like pathology results for a lesion). The text does not provide specifics.

    8. The sample size for the training set

    This information is not provided. Electrosurgical generators typically operate based on established physical principles and control algorithms, not machine learning models that require "training sets" in the conventional sense. The "software validation testing" is more about verifying correct implementation of these algorithms.

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

    This information is not provided and is not applicable as there is no mention of machine learning or a "training set" in the context of this device. The "ground truth" for verifying its function would be based on engineering specifications and regulatory standards.

    AI/ML Overview

    The provided text describes a 510(k) summary for the RITA® Model 1500X Electrosurgical RF Generator. This document is a regulatory submission for a medical device and, as such, does not contain the detailed information typically found in a clinical study report regarding acceptance criteria and performance data as requested in your prompt.

    Specifically, the text states:

    • Performance Data: "The Model 1500X RF Generator was subjected to a battery of electrical, mechanical, and software validation testing."
    • Performance Standards: "Performance standards have not been established by the FDA under section 514 of the Food, Drug and Cosmetic Act."

    This indicates that the submission relies on engineering and software validation rather than a clinical study evaluating the device's performance against specific clinical acceptance criteria in a human population. The focus is on demonstrating safety and efficacy through equivalence to a predicate device based on its intended use and technology, rather than a quantifiable clinical performance study with predefined acceptance metrics.

    Therefore, I cannot provide the requested information from the given text because:

    1. A table of acceptance criteria and the reported device performance: The document does not define specific clinical acceptance criteria or report clinical performance metrics. It refers to "electrical, mechanical, and software validation testing" but does not provide details of these tests or their results.
    2. Sample size used for the test set and the data provenance: Not applicable as no clinical test set is described.
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
    4. Adjudication method for the test set: Not applicable.
    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: Not applicable. This device is an electrosurgical generator, not an AI-assisted diagnostic tool.
    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable to this type of device submission.
    8. The sample size for the training set: Not applicable.
    9. How the ground truth for the training set was established: Not applicable.

    The document focuses on the intended use, device description, and regulatory classification, concluding that the device is "substantially equivalent" to a predicate device based on its design and safety testing, not on a clinical performance study with the metrics you've asked for.

    Intended Use

    The RITA® Clips are used with Harvard 2 Syringe Pump to increase the syringe holding capacity of the Pump from two to five syringes to allow one Harvard 2 Syringe Pump to supply local delivery of saline through multiple irrigation ports of one RITA® Electrosurgical Device of the RITA® System. The RITA System is intended for use in percutaneous. laparoscopic, or intraoperative coagulation and ablation of soft tissue, including the partial or complete ablation of non-resectable liver lesions.

    Device Description

    The RITA® Clips are a syringe holder accessory to the Harvard 2 Syringe Pump to accommodate five (5) 20-cc syringes.

    AI/ML Overview

    The provided text describes the 510(k) summary for the RITA® Clips, an accessory for the Harvard 2 Syringe Pump. The primary purpose of this submission is to demonstrate substantial equivalence to a predicate device and establish the safety and effectiveness of the RITA® Clips.

    Here's an analysis based on the requested information:

    1. Table of Acceptance Criteria and Reported Device Performance

    The provided document doesn't explicitly state quantitative acceptance criteria in a typical "pass/fail" numerical fashion for a and clinical study. Instead, it mentions functional tests.

    Acceptance Criteria CategoryStated VerificationReported Device Performance
    Flow Rate VerificationVerify the flow rate of the RITA® Clips combined with the Harvard 2 Syringe Pump."The RITA® Clips and Harvard 2 Syringe Pump underwent testing to verify flow rate... The devices passed the test criteria."
    Alarm Function VerificationVerify the alarm function of the RITA® Clips combined with the Harvard 2 Syringe Pump."The RITA® Clips and Harvard 2 Syringe Pump underwent testing to verify... alarm function. The devices passed the test criteria."
    Biocompatibility (Patient Contact)Not applicable as the device does not directly contact the patient."The RITA® Clips do not directly contact the patient therefore no biocompatibility testing was required."

    Interpretation: The acceptance criteria were broadly focused on ensuring the RITA® Clips did not negatively impact the fundamental functions (flow rate and alarm) of the associated Harvard 2 Syringe Pump. The document states these tests were "passed," implying the device met these functional requirements.

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

    The document describes performance data related to functional testing of the device rather than a clinical study with human subjects.

    • Sample Size for Test Set: The document does not specify a numerical sample size for the "testing to verify flow rate and alarm function." It simply states "The RITA® Clips and Harvard 2 Syringe Pump underwent testing." This likely implies testing of a sufficient number of units to ensure consistent performance, but the exact quantity isn't provided.
    • Data Provenance: The data provenance is prospective testing conducted by RITA Medical Systems to verify the functionality of the RITA® Clips when used with the Harvard 2 Syringe Pump. There is no mention of country of origin for, or retrospective use of, data.

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

    This question is not applicable to the provided information. The "testing to verify flow rate and alarm function" is a mechanical/electrical performance test, not a clinical study requiring expert assessment of ground truth. Ground truth in this context would be the actual flow rate or alarm activation, which is measured by instruments, not human experts.

    4. Adjudication Method for the Test Set

    This question is not applicable. Since the testing involved mechanical performance verification (flow rate and alarm function) rather than human interpretation or clinical outcomes, an adjudication method for a test set (e.g., 2+1, 3+1) is not relevant.

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

    No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. The RITA® Clips are a mechanical accessory (syringe holder) for an infusion pump. The study described is a verification of its mechanical function (flow rate and alarm) rather than a clinical study evaluating diagnostic accuracy or reader improvement. Therefore, the concept of human readers, AI assistance, or effect size for such improvement is not relevant to this submission.

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

    This question is not applicable in the context of the RITA® Clips.

    • The RITA® Clips are a mechanical device, not an algorithm or software.
    • The performance described is the physical functionality of the clips when attached to the pump, not an algorithm's output.
    • There is no "human-in-the-loop" interaction in the described performance testing; it's about the device's inherent function.

    7. The Type of Ground Truth Used

    The ground truth used for the performance testing was objective mechanical measurements.

    • For flow rate: The ground truth would be the accurately measured volume/time output from the pump system with the RITA® Clips installed, compared against the expected or desired flow rate.
    • For alarm function: The ground truth would be the correct activation of the pump's alarm under specific (e.g., occlusion, end-of-infusion) conditions.

    These are verifiable physical phenomena, not expert consensus, pathology, or outcomes data typically associated with diagnostic or therapeutic clinical trials.

    8. The Sample Size for the Training Set

    This question is not applicable. The RITA® Clips are a physical medical device, not an AI/ML algorithm or system that requires a "training set" in the computational sense. The described testing is performance verification of hardware.

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

    This question is not applicable, as there is no training set for this type of mechanical device.
