The Autosuture™ ENDO GIA™ Staplers with ENDO GIA™ Single Use Loading Units with Staple Line Reinforcement have applications in abdominal, gynecologic, pediatric and thoracic surgery for resection, transection and creation of anastomosis. They may be used for transection and resection of liver substance, hepatic vasculature and billary structures.

The Autosuture™ ENDO GIA™ Staplers with ENDO GIA™ Single Use Loading Units with Staple Line Reinforcement place two, triple-staggered rows of titanium staples and simultaneously divides the tissue between the two, triple-staggered rows. The size of the staples is determined by the selection of the 3.5 mm or 4.8 mm Single Use Loading Unit (SULU). The ENDO GIA™ UNIVERSAL Single Use Loading Units (SULUs) with Staple Line Reinforcement are only available in the straight and articulating 45 mm and 60 mm length cartridges with the 3.5 mm or 4.8 mm staples. The staple line reinforcement material is a synthetic absorbable film prepared from synthetic polyester composed of glycolide, dioxanone, and trimethylene carbonate. The staple line reinforcement material is supplied on each SULU undyed (natural) and is secured to the anvil and cartridge with BIOSYN™ synthetic absorbable suture. Studies indicate that the staple line reinforcement material can be expected to retain measurable mechanical strength through 14 days and absorption should be complete between 90 and 110 days.

The provided text describes a 510(k) summary for the Autosuture™ ENDO GIA™ Surgical Staplers with ENDO GIA™ Single Use Loading Units with Staple Line Reinforcement. However, it does not include information about specific acceptance criteria or an explicit study that proves the device meets those criteria in the context of a typical AI/software device evaluation.

The document mainly focuses on the device description, intended use, technological characteristics, and material safety. It states: "Performance evaluations were completed to verify that the Autosuture™ ENDO GIA™ Staplers with ENDO GIA™ Single Use Loading Units with Staple Line Reinforcement are safe and effective and perform as intended."

5. MRMC comparative effectiveness study: The document does not describe a study involving human readers with or without AI assistance.
6. Standalone (algorithm only) performance: This device is a surgical stapler, not an AI algorithm, so standalone algorithm performance is not applicable in the usual sense. Its performance is inherent to its mechanical function and material properties.
7. Type of ground truth used: Not applicable as it's a physical device and not an AI interpreting data. The "ground truth" for a physical device would relate to its mechanical integrity and biological interaction, which is assessed through various engineering and biocompatibility tests.
8. Sample size for the training set: Not applicable as this is a physical device, not an AI system that requires a training set.
9. How the ground truth for the training set was established: Not applicable for the same reason.

The "performance evaluations" mentioned in the document likely refer to laboratory testing, mechanical robustness tests, biocompatibility assessments, and potentially animal studies, which are standard for surgical devices, rather than clinical studies involving human readers or AI algorithms that would generate the kind of data you're asking for.

The Cool-tip™ Switching Controller is to be used with the Cool-tip™ RF System and is intended for use in percutaneous, laparoscopic, intraoperative coagulation and ablation of tissue, such as the partial or complete ablation of non-resectable liver tumors, and osteoid osteoma tumors within bone.

The Cool-tip™ Switching Controller (CTSW Control) is an adjunct device for the Cooltip™ RF Ablation Generator. Power from the generator is routed to the controller and allows the physician to ablate lesions with one single Cool-tip electrode or one cluster electrode, or simultaneously with two or three single pre-placed electrodes. The controller sequentially switches power between the electrodes. Power is applied to the first electrode until the tissue impedance rises to the target value (30 percent above the baseline value), or until 30 seconds have elapsed. Then power is switched to the next electrode. Power is switched repeatedly until the selected procedure time is reached. The controller does not alter the basic functions available on the generator. The controller has the same timing, temperature measurement, and impedance measurement functions available on the generator. The controller does not change the power available at the electrodes compared to the generator without the controller. The indications for use and the control mechanisms for the Switching Controller remain the same as for the generator. The Switching Controller is an accessory that allows for the simultaneous activation of multiple electrodes. Activation of multiple electrodes during a single treatment session is a convenience for the physician and allows for the ablation of multiple lesions simultaneously, or for the ablation of one large tumor when the electrodes are placed 2 cm apart. Placing three single electrodes in close proximity produces a cluster electrode where the physician is controlling the cluster spacing. The controller automates the manual function of cauterization of the electrode track by controlling the temperature during electrode removal. The front panel of the Switching Controller contains an on/off power switch, activation switches for ablation and cauterization, ablation timer displays and buttons, three (3) electrode ports for the connection of selected electrodes, three (3) buttons for activating selected electrode channels, three (3) temperature probe displays with adjacent green bars to indicate the activated electrode channel, and three (3) current/watts displays for each electrode channel. The Cool-tip™ Switching Controller is comprised of the following components: Switching controller, Cable, which delivers power from the generator to the controller. The Switching Controller is connected to the Cool-tip RF generator by a dedicated cable that delivers power from the generator to the switching controller. The Switching Controller cannot direct power to the electrodes without the generator.

The Cool-tip™ Switching Controller is an adjunct device for the Cool-tip™ RF Ablation Generator, designed to facilitate the simultaneous activation of multiple electrodes. It routes power from the generator, allowing the physician to ablate lesions with one single electrode, one cluster electrode, or simultaneously with two or three pre-placed electrodes. The controller sequentially switches power between electrodes until the selected procedure time is reached. It also automates the manual function of cauterization during electrode removal.

Here's an analysis of the acceptance criteria and the study that proves the device meets them:

1. Table of Acceptance Criteria and Reported Device Performance

The provided text does not explicitly state numerical acceptance criteria for a specific performance metric (like accuracy, sensitivity, or specificity). Instead, the acceptance is based on the device demonstrating safety and efficacy comparable to a predicate device. The key performance aspect is the ability of the switching controller to produce similar therapeutic effects (lesions) as the predicate device when using various electrode configurations.

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

The study involved preclinical testing on bovine liver, both ex vivo (outside the body) and in vivo (in a living organism). The document does not specify a precise numerical sample size (e.g., number of livers, number of ablation procedures, or number of electrodes tested).

However, the data provenance is clearly stated as bovine liver, indicating an animal model. The study is described as "preclinical testing," implying it's a prospective study designed to compare the new device to the predicate.

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

The document does not provide information on the number or qualifications of experts used to establish ground truth for the test set.

4. Adjudication Method for the Test Set

The document does not describe any specific adjudication method for the test set. The comparison of lesion characteristics likely involved direct measurement and observation rather than expert consensus on a diagnostic outcome.

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

No, an MRMC comparative effectiveness study was not conducted. This device is an accessory to an existing RF ablation system and its performance demonstration focuses on the equivalence of the generated lesions, not on diagnostic accuracy involving human readers.

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

This question is not applicable in the context of this device. The Cool-tip™ Switching Controller is a hardware accessory that automates power delivery for RF ablation electrodes. It does not involve algorithms for interpretation or generate diagnostic outputs that would have a "standalone performance" in the typical sense of AI/software. Its performance is intrinsically tied to its interaction with the RF generator and electrodes.

7. The Type of Ground Truth Used

The ground truth for this study was based on the characteristics of the lesions produced by the RF ablation. The statement "lesions produced... are comparable" implies a physical assessment of ablation zones (e.g., size, shape, completeness) as the reference for comparison. This would likely involve macroscopic and/or microscopic examination of the ablated tissue.

8. The Sample Size for the Training Set

The document does not mention a training set. This is not a machine learning device, so the concept of a training set as used in AI development is not applicable here.

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

As there is no training set for this hardware device, this question is not applicable.

The ForceTriad™ is a full-featured electrosurgical generator intended for open and laparoscopic surgical procedures where the surgeon requires electrosurgical cutting, coagulation, or vessel sealing (tissue fusion). The generator is intended for use in general, laparoscopic and gynecologic surgical procedures where ligation of vessels, pulmonary vasculature, or lymph vessels, is desired. The system creates a vessel ligation (seal) by the application of bipolar electrosurgical RF energy (coagulation) to vessels interposed between the jaws of the device. The generator can also be used with standard bipolar devices where bipolar cutting or coagulation is desired.

The indications for use include general (including urologic, thoracic, plastic and reconstructive), laparoscopic, and gynecological procedures where electrosurgical cutting and coagulation of tissue, and sealing (fusion) of vessels, including pulmonary vessels, and tissue bundles is performed. including such procedures as bowel resections, hysterectomies (both vaginal and abdominal), laparoscopic cholesystectomies, laparoscopically assisted vaginal hysterectomies, gall bladder procedures, Nissen fundoplication, adhesiolysis, oophorectomy, etc. The devices can be used on vessels (arteries, veins, pulmonary arteries, pulmonary veins, lymph) up to 7mm and bundles as large as will fit in the jaws of the instruments.

The LigaSure tissue fusion function has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use this function for these procedures.

The ForceTriad™ generator is a full-featured electrosurgical generator with monopolar, bipolar, and Valleylab LigaSure™ vessel sealing outputs. This 510(k) only applies to the LigaSure™ Vessel sealing portion of the generator. The generator is electrically isolated, microcontroller-based device, incorporating closed-loop control for all output modes implemented in the microcontroller firmware. The generator incorporates Instant Response™ technology to constantly measure the electrical impedance of the tissue and instantaneously adjust the generator output to maintain the desired power.

The generator is used with a selection of instruments designed for use with the ForceTriad and the LigaSure Vessel Sealing generator. All of the instruments are capable of sealing vessels up to, and including, 7mm, and tissue bundles as large as can fit in the jaws of each instrument. When a LigaSure™ instrument is applied to a vessel or tissue bundle and RF energy is applied, the collagen and elastin in the tissues are reformed by heat and pressure to fuse vessel walls, thereby forming a permanent seal. The microprocessor in the generator monitors the tissue properties, stops the application of energy, and allows a brief period of cooling before indicating that cycle is complete.

No changes are being made to the design or operation of any of the devices within the current system. The change as proposed in this 510(k) notification is to the intended use as described above and the resulting labeling changes.

This document describes the ForceTriad™ Electrosurgical Generator, specifically its LigaSure™ Vessel Sealing System component. The submission is a 510(k) for a change in intended use and labeling, as the technological characteristics of the device have not been modified.

Here's an analysis of the provided information regarding acceptance criteria and supporting studies:

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

   The document does not explicitly state quantitative acceptance criteria in a table format. However, it implicitly defines successful performance for the LigaSure™ vessel sealing function:

   Acceptance Criteria (Implied)	Reported Device Performance
   Effective sealing of pulmonary vasculature	Pre-clinical studies (acute and chronic) and bench testing have shown that the ForceTriad Electrosurgical Generator effectively seals pulmonary vasculature.
   Seals with burst pressures substantially greater than physiologic pressures in the vessels	Pre-clinical studies (acute and chronic) and bench testing have shown that the ForceTriad Electrosurgical Generator produces seals with burst pressures substantially greater than the physiologic pressures in the vessels.
   Capability to seal vessels up to and including 7mm	All of the instruments are capable of sealing vessels up to, and including, 7mm. The devices can be used on vessels (arteries, veins, pulmonary arteries, pulmonary veins, lymph) up to 7mm.
   Capability to seal tissue bundles as large as can fit in the jaws of each instrument	All of the instruments are capable of sealing tissue bundles as large as can fit in the jaws of each instrument. The devices can be used on... bundles as large as will fit in the jaws of the instruments.
   Formation of a permanent seal to fuse vessel walls	When a LigaSure™ instrument is applied to a vessel or tissue bundle and RF energy is applied, the collagen and elastin in the tissues are reformed by heat and pressure to fuse vessel walls, thereby forming a permanent seal. The microprocessor in the generator monitors the tissue properties, stops the application of energy, and allows a brief period of cooling before indicating that cycle is complete.

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

   The document states: "Pre-clinical studies (acute and chronic) and bench testing have shown that the ForceTriad Electrosurgical Generator effectively seals pulmonary vasculature..."

   • Sample size: Not specified.
   • Data provenance: Not specified, but "pre-clinical studies" generally implies laboratory or animal studies, and "bench testing" is laboratory-based. No information on country of origin is provided. Both would be considered prospective studies in their design.

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. The performance is assessed through objective biophysical measurements (e.g., burst pressure) and physical observation of sealing, not through expert human interpretation of images or clinical outcomes that require expert consensus for ground truth.

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

   Not applicable. Adjudication methods like 2+1 are typically used for establishing ground truth from multiple human readers, often in image-based diagnostic studies. This study relies on objective physical measurements and observations.

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 a medical device performance study, not a diagnostic AI study involving human readers.

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

   Yes, the performance data presented is for the device operating in a standalone manner. The device itself (the ForceTriad™ Electrosurgical Generator with its LigaSure™ functionality) is assessed based on its ability to achieve effective vessel sealing and high burst pressures, without human intervention in the sealing process once initiated. The human's role is in operating the device, not in interpreting its output for the technical performance measurements.

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

   The ground truth is established through objective biophysical measurements (e.g., burst pressure testing) and direct observation of physical outcomes (e.g., effective sealing/fusion of vessels). This type of ground truth is based on engineering and physiological principles rather than expert interpretation of medical data.

8. The sample size for the training set

   Not applicable. This device is not an AI/machine learning model in the sense that it requires a "training set" of data to develop its algorithm. The device's operation is based on established electrosurgical principles and a microcontroller-based closed-loop control system. Its parameters are likely determined through engineering design and validation, not a data-driven training process.

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

   Not applicable, as there is no "training set" in the context of this electrosurgical generator's design and validation described here.

A tip has been added to the CUSA Excel system to enable it to abrade bone. Testing was completed to demonstrate that the tip will abrade bone. The tip is manufactured from the same materials as in the other CUSA Excel tips.

The provided text is a 510(k) summary for the Radionics CUSA Excel Ultrasonic Surgical Aspirator System with Bone Tip. This document describes the device, its intended use, and its substantial equivalence to predicate devices. However, it does not contain any information about acceptance criteria, device performance metrics (such as accuracy, sensitivity, specificity), sample sizes for test sets or training sets, expert qualifications, adjudication methods, or results from comparative effectiveness studies.

The text simply states: "Testing was completed to demonstrate that the tip will abrade bone." This is a general statement and does not provide quantified performance data or details of a study that would establish specific acceptance criteria.

Therefore, I cannot fulfill the request to provide the detailed information required for the table and all the numbered points because the provided document does not contain this type of performance study data.

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

This information is not provided in the given text. A 510(k) submission primarily focuses on demonstrating substantial equivalence to existing predicate devices, often through comparison of design, materials, and intended use, rather than presenting a novel clinical study with a test set of patient data to prove effectiveness. If any testing was done (e.g., bench testing for mechanical properties), details about the sample size and data provenance are not included here.

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

This information is not provided. Given that this is a 510(k) submission for a biopsy needle and not an AI/diagnostic device, the concept of "ground truth" and expert adjudication in the context of a test set for performance evaluation is generally not applicable in the same way as for an image analysis or diagnostic support system. If any expert evaluation for tissue integrity or diagnostic quality was performed on samples, it is not detailed here.

4. Adjudication Method for the Test Set

This information is not provided. As with point 3, the concept of an adjudication method for a test set is typically associated with studies involving diagnostic performance or interpretation, which is not the primary focus of this 510(k) submission for a biopsy needle.

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

This information is not applicable and not provided. A MRMC comparative effectiveness study is relevant for AI-assisted diagnostic tools (e.g., image analysis software). The Radionics Nashold Biopsy Needle is a physical medical device, not an AI or diagnostic software, and therefore, an MRMC study comparing human readers with and without AI assistance is not relevant to its clearance.

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

This information is not applicable and not provided. This type of study is relevant for algorithms performing tasks independently. As the device is a physical biopsy needle, this concept does not apply.

7. The Type of Ground Truth Used

This information is not explicitly stated or readily applicable in the context of this 510(k) submission. For a biopsy needle, "ground truth" might refer to histological confirmation of tissue obtained by the needle, or the accuracy of the biopsy procedure itself. However, the provided document does not detail such studies or the ground truth establishment method.

8. The Sample Size for the Training Set

This information is not applicable and not provided. The concept of a "training set" is relevant for machine learning algorithms. The Radionics Nashold Biopsy Needle is a physical, mechanical device, and does not involve an algorithm that requires a training set.

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

This information is not applicable and not provided. As explained in point 8, there is no training set for this type of device.

Summary of Available Information from the 510(k) (K032054):

The provided text from K032054 primarily focuses on regulatory clearance by demonstrating substantial equivalence to predicate devices (MRI Devices Corporation's Daum Neurocut Neurobiopsy Needle, Ad-Tech's Brain Biopsy Needle For Stereotaxic, and Elekta Instrument's Leksell Sedan Biopsy Needle). It describes the device's design, materials, and intended use. It does not contain detailed performance studies, specific acceptance criteria with quantitative results, or information about clinical trials, test sets, or ground truth establishment that would be typically found for novel diagnostic algorithms or devices requiring extensive clinical validation. The FDA's decision to clear the device is based on its similarity to legally marketed devices, subject to general controls.
