    AI/ML Overview

    The provided document is a 510(k) summary for medical devices, specifically Peri-Guard and Supple Peri-Guard surgical meshes. This type of document is used to demonstrate substantial equivalence to a predicate device, not to present a study proving a device meets specific acceptance criteria for AI/ML performance.

    Therefore, the information required to answer your prompt regarding acceptance criteria and performance studies (e.g., sample sizes, expert involvement, adjudication methods, MRMC studies, ground truth establishment, training set details) is not present in the provided text. The document focuses on demonstrating the safety and effectiveness of a material and physical design change (sterilization method and packaging) for a surgical mesh, not on evaluating the performance of an AI-driven medical device.

    To directly address your request for a table of acceptance criteria and study details, based solely on the provided text, I must state that this information is not available.

    The document details non-clinical bench testing and animal studies to support the substantial equivalence claim for the modified surgical mesh. These studies are focused on material properties, biocompatibility, and physical performance of the mesh, and not on the performance of an AI model.

    Here's how I would summarize the relevant information from the document, while acknowledging the absence of AI/ML-specific details you requested:


    Acceptance Criteria and Device Performance (as described for the surgical mesh, not an AI device):

    The document does not present a table of quantitative acceptance criteria for the mesh's performance in the way one would for an AI model (e.g., sensitivity, specificity, AUC thresholds). Instead, it discusses the equivalence of the modified device to its predicate through various non-clinical and animal studies. The overall "acceptance criterion" implicit in a 510(k) is the demonstration of substantial equivalence to a predicate device, meaning the new device is as safe and effective as the legally marketed predicate.

    Reported Device Performance (for the surgical mesh):

    The document states that the results of performance testing demonstrate that the modified PERI-GUARD and SUPPLE PERI-GUARD devices are substantially equivalent to the predicate devices.

    Specific performance aspects evaluated include:

    • Bench Testing: Visual, Suture retention, Dimensional, Burst strength, Collagenase digestion, Denaturation Temperature, Water Permeability, Pliability, Chemical and heavy metal residuals, Bioburden, Pyrogenicity/Endotoxins, Temperature Excursion Testing.
      • Conclusion: The results of these tests support substantial equivalence.
    • Animal Studies:
      • Implantation (Porcine incisional hernia repair model for 6 months per ISO 10993-6): "No test material-related changes among clinical observations, bodyweights, veterinary physicals, clinical pathology parameters, mortality, significant macroscopic or microscopic differences, tensile or burst strength, or clinical performance between the subject and predicate devices..."
        • Conclusion: "The subject and predicate devices performed equivalently and had an equivalent safety profile in the in vivo porcine model for incisional hernia repair."
      • 3-week Rat Calcification Potential Study: "No significant mineralization was noted microscopically for either the subject or predicate device."
        • Conclusion: "No significant difference in calcification potential."
    • Biocompatibility: Demonstrated biocompatibility in accordance with ISO 10993-1:2018 for a permanent implant, including cytotoxicity, sensitization, acute systemic toxicity, pyrogenicity, genotoxicity, implantation, hemolysis, and subchronic toxicity endpoints.
    • Shelf Life: 1-year shelf life claim supported by aging testing.
    • Sterilization and Packaging: Validation per ISO 11137 parts 1 and 2 (sterilization) and ISO 11607-1 (packaging integrity, supported by ASTM F88-15 and ASTM F2096-11).
    • Human Factors Testing: Confirmed that redesigned packaging allows for aseptic transfer without compromising sterility and does not impact the tissue patch surface.

    Detailed breakdown of AI/ML specific information (Not Found in these documents):

    1. A table of acceptance criteria and the reported device performance: Not applicable, as this is not an AI/ML device.
    2. Sample size used for the test set and the data provenance: Not applicable. Studies conducted were animal (porcine and rat) and bench tests.
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for the mesh's performance attributes (e.g., tensile strength, burst strength, calcification) is established through standardized laboratory and animal model measurements, not expert consensus interpreting images/data.
    4. Adjudication method (e.g. 2+1, 3+1, none) 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.
    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): The "ground truth" for this device's performance relies on direct physical measurements (e.g., tensile strength, burst strength), chemical analysis (e.g., residuals), and histopathological evaluation in animal models. It's not a diagnostic AI that generates predictions requiring expert-adjudicated ground truth labels.
    8. The sample size for the training set: Not applicable. This device is a physical product, not an AI model requiring a training set.
    9. How the ground truth for the training set was established: Not applicable.

    In conclusion, the provided FDA 510(k) summary is for a traditional medical device (surgical mesh) and lacks any information pertaining to AI/ML device performance, acceptance criteria, or study methodologies.

    AI/ML Overview

    This is a 510(k) premarket notification for the PERI-GUARD Repair Patch and SUPPLE PERI-GUARD Repair Patch. This document describes the device, its intended use, and the performance data provided to demonstrate substantial equivalence to predicate devices. The submission focuses on changes to packaging and sterilization parameters, with a reliance on historical data for many performance aspects.

    Here's the breakdown of the acceptance criteria and the study information:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not explicitly present a table of "acceptance criteria" with numerical targets and corresponding "device performance" results for each criterion in the typical sense of a clinical or standalone performance study. Instead, it lists various performance tests conducted to support substantial equivalence. The "reported device performance" is implicitly that the devices "meet" or "demonstrate equivalence" to the predicate devices.

    Acceptance Criteria (Implied)Reported Device Performance
    Visual AppearanceMet (Implied, by not noting any issues)
    Suture Retention StrengthEquivalent to predicate devices (Implied)

    Packaging IntegritySupported by testing per ISO 11607-1, ASTM F88-15, ASTM F2096-11
    Aseptic Transfer (Human Factors)Confirmed by human factors testing

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

    The document does not specify exact sample sizes for each performance test. It mentions "aging testing" for shelf life, but without a specific sample size. The studies are non-clinical (laboratory/bench testing, in vitro), not based on patient data. Therefore, questions about country of origin and retrospective/prospective nature are not applicable in this context.

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

    Not applicable. This is a submission for a medical device (a patch), and the evaluation is based on non-clinical performance data and substantial equivalence to existing devices, not on diagnostic accuracy against a "ground truth" established by human experts.

    4. Adjudication Method for the Test Set

    Not applicable. See point 3.

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

    Not applicable. This is a physical medical device, not an AI/software as a medical device (SaMD) that involves human readers or AI assistance.

    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 or AI.

    7. The Type of Ground Truth Used

    Not applicable in the context of diagnostic accuracy. For the performance tests listed, the "ground truth" or reference standards are the established industry standards, test methodologies (e.g., ASTM, ISO), and the performance characteristics of the predicate devices. For example, for "Burst Strength," the "ground truth" would be the measurement obtained using a validated testing procedure, and the performance would be compared to that of the predicate.

    8. The Sample Size for the Training Set

    Not applicable. This is a physical medical device, not an AI/ML algorithm that requires a "training set."

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

    Not applicable. This is a physical medical device, not an AI/ML algorithm.

    Intended Use

    VASCU-GUARD Vascular Repair Patch is used in peripheral vascular reconstruction including the carotid, renal, iliac, femoral, profunda and tibial vessels and arteriovenous access revisions.

    Device Description

    VASCU-GUARD Vascular Repair Patch (VASCU-GUARD) is derived from bovine pericardium procured from cattle originating in the United States. The pericardium is cross-linked with glutaraldehyde and treated with 1 molar sodium hydroxide for a minimum of 60 minutes at 20-25° (68-77°F). VASCU-GUARD is terminally sterilized using gamma irradiation and packaged within a sterile double-pouch system. The contents of the unopened, undamaged outer pouch are sterile. VASCU-GUARD is MR Safe. VASCU-GUARD utilizes animal tissue; patient must be informed prior to any procedure.

    AI/ML Overview

    The provided text is a 510(k) summary for the VASCU-GUARD Vascular Repair Patch. It describes the device, its intended use, and comparison to predicate devices, along with performance data. However, this document does not contain information about acceptance criteria or specific studies that demonstrate the device meets those criteria in the context of an AI/ML medical device.

    The performance data listed (Visual, Suture retention, Dimensional, Burst strength, Collagenase digestion, Denaturation Temperature, Water Permeability, Pliability, Chemical and heavy metal residuals, Bioburden, Pyrogenicity/Endotoxins, Temperature Excursion Testing, Biocompatibility Assessment) are for physical and material properties of the vascular repair patch itself, not for an AI/ML algorithm's diagnostic or predictive performance.

    Therefore, I cannot provide the requested information regarding acceptance criteria, device performance, sample sizes, ground truth, expert qualifications, adjudication methods, or MRMC studies for an AI/ML device, as the supplied text pertains to a physical medical device (a vascular repair patch) and not an AI/ML product.

    PSDV-SG can be used for reinforcement of staple lines during bariatric, gastric, small bowel, colon and colorectal procedures.

    Device Description

    PERI-STRIPS DRY Staple Line Reinforcement with VERITAS Collagen Matrix with SECURE GRIP Technology is prepared from dehydrated bovine pericardium procured from cattle under 30 months of age, originating from the United States.

    There are two types of PSDV-SG configurations based on the tissue buttress thickness range. The Standard configuration has a tissue buttress thickness range of 0.20-0.60mm. The Thin configuration has a tissue buttress thickness range of 0.20-0.40mm.

    The product consists of a loading unit which includes two (2) buttresses, one for the anvil and one for the cartridge side of the stapler. The buttresses are held in a foam/sheath configuration for loading of the buttress to the stapler jaws. Each buttress has acrylic adhesive on one side for attachment to the stapler surfaces. Each PSDV-SG loading unit is packaged sterile in a separate pouch.

    PSDV-SG utilizes animal tissue; patient must be informed prior to any procedure.

    PSDV-SG is provided sterile and intended for single use. Sterilization is accomplished via ethylene oxide (ETO). The bovine pericardium buttress and acrylic adhesive are considered permanent implants per ISO 10993-1 Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process.

    AI/ML Overview

    This document describes the PERI-STRIPS Dry Staple Line Reinforcement with VERITAS Collagen Matrix with SECURE GRIP Technology (PSDV-SG) device, which is a surgical mesh intended for staple line reinforcement. It is a Special 510(k) submission, meaning the changes are relatively minor compared to a predicate device.

    Based on the provided text, here's a breakdown of the acceptance criteria and study information:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not explicitly state "acceptance criteria" in a quantitative, pass/fail manner with numerical targets for clinical performance metrics (e.g., specific reduction in anastomotic leaks, burst pressure thresholds). Instead, it focuses on demonstrating substantial equivalence to a predicate device by showing that the technological characteristics and performance (functional, manipulation, dimensional, usability, and shelf-life) are similar.

    The "performance" described is largely comparative to the predicate device and verification/validation results. The core of the performance claim is that the device maintains the same intended use, indications for use, materials, and principles of operation as the predicate, despite changes in size and design for stapler compatibility.

    Acceptance Criteria CategorySpecific Criteria (Implicit/Explicit from text)Reported Device Performance
    Intended UseSame as predicate device (K192615)SAME
    Indications for UseSame as predicate device (K192615)SAME
    MaterialsSame as predicate deviceSAME (bovine pericardium, acrylic adhesive)
    Principle of OperationSame as predicate deviceSAME (non-cross-linked collagen tissue technology for neo-collagen formation, neovascularization, and remodeling)
    Manipulation TestingPerformed to demonstrate device's handling characteristicsPerformed, specific results not detailed but support substantial equivalence.
    Functional TestingPerformed to demonstrate device's operational capabilitiesPerformed, specific results not detailed but support substantial equivalence.
    Dimensional TestingPerformed to ensure correct sizing and fit for stapler compatibilityPerformed, specific results not detailed but support substantial equivalence.
    Usability TestingPerformed to assess ease of use and user interactionPerformed, specific results not detailed but support substantial equivalence.
    Shelf-lifeStability over time1 year with testing to 3 years ongoing (predicate had 3 years). This is a difference, but presumably accepted by FDA.
    Stapler CompatibilityCompatibility with specified stapler models (new models compared to predicate)Predicate: Ethicon Echelon ENDOPATH Staplers (K163455, K160521, K140560). Subject Device: Medtronic Endo GIA Staplers (K111825) and Intuitive Surgical SureForm Staplers (K173721). This is a key difference addressed by the Special 510(k).

    Note: The document states "Verification and validation of the product have been completed using the same test methods as the predicate device, or accepted industry standard methods. No new issues of safety and effectiveness have been identified." This implies that the results from these tests met the internal acceptance criteria established by the manufacturer, which were aligned with the predicate or industry standards. However, the specific numerical acceptance criteria (e.g., minimum burst pressure, maximum staple pull-through force) are not provided in this summary.

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

    The document states "Testing performed to support the new product models subject of this submission included manipulation, functional, and dimensional testing, as well as usability and shelf-life." It does not provide details on the sample sizes used for these tests.

    Regarding data provenance:

    • Country of Origin: Not specified for the testing data.
    • Retrospective or Prospective: Not specified. These appear to be benchtop and perhaps simulated use tests, not clinical studies involving patients.

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

    N/A. This submission focuses on engineering and bench testing performance for substantial equivalence, not clinical diagnostic accuracy or efficacy. There is no mention of "ground truth" derived from expert review in the clinical sense.

    4. Adjudication Method for the Test Set

    N/A. As there's no mention of expert review or clinical studies for ground truth establishment, no adjudication method is described.

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

    No. There is no mention of a human reader or AI comparative effectiveness study. This device is a surgical mesh, not a diagnostic imaging or AI-assisted interpretation device.

    6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

    N/A. This device is a physical surgical mesh, not a software algorithm.

    7. The Type of Ground Truth Used

    For the engineering and functional tests conducted, the "ground truth" would be established by:

    • Measurement Standards: Adherence to predefined dimensional and physical property specifications.
    • Performance Specifications: Meeting functional requirements (e.g., tear strength, adhesion, burst pressure if these were tested) derived from predicate device performance or industry standards.
    • Visual Inspection: For manipulation and usability tests, often a qualitative or semi-quantitative assessment against predefined criteria.

    No pathology or outcomes data is mentioned as "ground truth" in this context of bench testing for substantial equivalence for the device itself.

    8. The Sample Size for the Training Set

    N/A. This device is not an AI/ML algorithm that requires a training set.

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

    N/A. Not an AI/ML device.

    AI/ML Overview

    This document is a 510(k) summary for a medical device called PERI-STRIPS Dry Staple Line Reinforcement with VERITAS Collagen Matrix with SECURE GRIP Technology (PSDV-SG). It describes the device, its intended use, comparison to predicate devices, and performance data.

    Here's an analysis of the provided text to extract information about acceptance criteria and the study that proves the device meets them:

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

    The document lists various assessments for design verification. It doesn't present these as formal "acceptance criteria" with specific pass/fail values in a table, but rather as "assessments" with the general outcome mentioned as "Testing passed the acceptance criteria" for biocompatibility and "demonstrate the performance of the PSDV-SG device is substantially equivalent to the predicate devices" for bench testing.

    Based on the text, here's a conceptual table:

    Assessment/Criteria CategorySpecific AssessmentReported Device Performance/Outcome

    Clinical FeedbackSurgeon ValidationCompleted and supports customer satisfaction of PSDV-SG functionality.

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

    • Sample Sizes: The document does not specify sample sizes for any of the tests (bench studies, biocompatibility, human factors, or surgeon validation). It broadly mentions "testing" or "studies" without numerical details.
    • Data Provenance: The document implies that the data was generated by Synovis Life Technologies, Inc. (now Baxter International Inc.) as part of their 510(k) submission. There is no information about the country of origin of the data explicitly stated. The studies are pre-clinical bench studies and validation studies, which are typically conducted in a controlled environment as part of product development, not necessarily from a "retrospective" or "prospective" clinical data sense.

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

    • Number of Experts: Not specified.
    • Qualifications of Experts: Not specified.
      • For the "Human Factors Study," "user comprehension" was assessed, implying user participants, but not "experts" in the sense of ground truth establishment.
      • For the "Surgeon Validation," "surgeons" were involved, but their number and specific qualifications (e.g., years of experience, specialty) are not provided. They were involved in assessing functionality and satisfaction, not necessarily establishing a "ground truth" that would be typical for, say, an AI model's diagnostic accuracy.

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

    • Not applicable / None specified. The studies described (bench, biocompatibility, human factors, surgeon validation) do not involve subjective interpretation of medical images or data requiring an adjudication method common in diagnostic accuracy studies. They are focused on physical and functional performance, safety, and usability.

    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:

    • No MRMC study was done. This device is a surgical mesh for staple line reinforcement, not a diagnostic imaging device or an AI-assisted diagnostic tool. Therefore, a study comparing human reader performance with and without AI assistance is irrelevant and was not conducted.

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

    • Not applicable. This is a physical medical device (surgical mesh), not an algorithm or AI. Standalone performance for an algorithm is not relevant here.

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

    • Not applicable in the typical sense of diagnostic "ground truth." For this device, "ground truth" relates to the functional performance of the device against engineering specifications, biocompatibility standards, and usability criteria.
      • For bench testing, the "ground truth" is likely defined by engineering specifications and comparative performance to predicate devices.
      • For biocompatibility, the "ground truth" is defined by the passing criteria of the ISO 10993-5 standard.
      • For human factors, "ground truth" is user comprehension and ability to use the device as intended.
      • For surgeon validation, "ground truth" is customer satisfaction and functionality assessment by the surgeons.

    8. The sample size for the training set:

    • Not applicable. This device is not an AI/ML algorithm that requires a "training set."

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

    • Not applicable. As above, no training set for an AI/ML algorithm.

    Intended Use

    The Flow COUPLER Device is a single use, implantable device that is intended to be used in the end-to-end anastomosis of veins and arteries normally encountered in microsurgical and vascular reconstructive procedures. The Flow COUPLER Device includes a pair of permanently implanted rings which secure the anastomosis and a removable Doppler probe that is press-fit onto one of the rings. When the Flow COUPLER Device is used in conjunction with the Flow COUPLER Monitor, the Flow COUPLER System is intended to detect blood flow and confirm vessel patency intra-operatively and post-operatively at the anastomotic site. Post-operatively, blood flow can be detected on an as needed basis for up to 7 days. The Flow COUPLER Doppler probe is not intended to be a permanent implant and should be removed 3 to 14 days post-operatively.

    Device Description

    The Flow COUPLER System consists of a Flow COUPLER Device and a Flow COUPLER Monitor. The Flow COUPLER Device is a sterile, single-use implantable pair of rings molded out of high density polyethylene with stainless steel pins on each ring. The Flow COUPLER Device is designed to serve as a mechanical, sutureless device for connecting veins or arteries. A probe-holder feature is molded on one Flow COUPLER ring and serves as the press-fit point of attachment for a pre-attached 20 MHz Doppler probe. The Doppler probe connects to the Flow COUPLER Monitor unit, via the external lead.

    The Flow COUPLER Monitor and Doppler probe is a pulsed Doppler ultrasound system designed for the detection of blood flow in vessels. An audible ultrasonic signal is produced when the Doppler probe detects blood flow.

    The Flow COUPLER Device and System has been specifically designed for use in end-to-end anastomosis of blood vessels and the detection of blood flow at the anastomotic site. On an as needed basis, blood flow can be detected for up to 7 days. The Flow COUPLER rings are intended to be a permanent implant. The Flow COUPLER probe is not intended to be a permanent implant; the probe should be removed, by gentle traction on the external lead, 3 to 14 days post-operatively.

    AI/ML Overview

    The provided document is a 510(k) Premarket Notification from the FDA for the GEM™ Flow COUPLER™ Device and System. The document focuses on establishing substantial equivalence to a predicate device rather than presenting a standalone study with detailed acceptance criteria and performance metrics of a new device.

    Therefore, many of the requested details about acceptance criteria, specific study design, sample sizes, ground truth establishment, and expert involvement are not explicitly present in the provided text. The document states that the modified Flow Coupler device is considered substantially equivalent to its own predicate (K142609), which is the GEM Flow COUPLER Device and System.

    Here's an attempt to answer the questions based on the information available:

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

    The document does not provide a table with quantitative acceptance criteria and reported device performance in the way a clinical study or performance verification study for a new device might. Instead, it states that "functional specifications were not affected by the line extension" for the 4.0mm Flow COUPLER. The acceptance criteria would broadly be that the modified device performs equivalently to the predicate device across the listed tests.

    Acceptance Criteria (Inferred)Reported Device Performance
    Functional specifications not affected by size range extension"functional specifications were not affected by the line extension" (for 4.0mm Flow COUPLER)
    Shock and vibration performance maintainedTesting included: "shock and vibration" (implies performance was acceptable/equivalent to predicate)
    Pin alignment maintainedTesting included: "pin alignment" (implies performance was acceptable/equivalent to predicate)
    Ring retention maintainedTesting included: "ring retention" (implies performance was acceptable/equivalent to predicate)
    Probe signal maintainedTesting included: "probe signal" (implies performance was acceptable/equivalent to predicate)
    Ring separation maintainedTesting included: "ring separation" (implies performance was acceptable/equivalent to predicate)
    Probe to COUPLER separation force maintainedTesting included: "probe to COUPLER separation force" (implies performance was acceptable/equivalent to predicate)
    Device is substantially equivalent to predicate device"The risk assessment and bench testing of this device demonstrate that the device is substantially equivalent to the predicate device."

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

    The document mentions "bench testing on the 4.0mm Flow COUPLER line extension," but it does not specify the sample size for any of these tests. The data provenance is not mentioned, but given it's a submission to the US FDA and the company is based in the US, it's highly likely the testing was conducted in the US. The nature of "bench testing" implies it's a prospective series of tests performed on physical devices.

    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 in the document. For bench testing of physical properties, "experts" in the clinical sense are typically not involved; rather, engineering and quality assurance personnel conduct the tests against specifications.

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

    This information is not provided. Adjudication methods are highly relevant for clinical studies or studies involving human interpretation. For bench testing of functional specifications, the results are usually objective measurements against predefined engineering tolerances.

    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

    There is no mention of an MRMC study or AI assistance in this document. The device is a mechanical coupler with an ultrasonic Doppler probe, not an AI diagnostic tool.

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

    This is not applicable. The device is not an algorithm, but a physical medical device. It has a "standalone" function in the sense that the Doppler probe detects blood flow independently, but it is not an AI algorithm.

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

    For the bench tests, the "ground truth" would be the engineering specifications and established functional parameters of the predicate device or industry standards for similar devices. For example, for "ring retention" or "probe signal," there would be quantifiable metrics and tolerances that the device must meet.

    8. The sample size for the training set

    There is no mention of a training set. This type of test is for a physical device, not a machine learning model.

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

    This is not applicable as there is no training set mentioned.

    SUPPLE PERI-GUARD is packaged between two pieces of foam within a double sterile barrier pouch system. The contents of the unopened, undamaged package are sterile.

    PERI-GUARD is prepared from bovine pericardium which is cross-linked with glutaraldehyde. PERI-GUARD has been treated with 1 molar sodium hydroxide for 60-75 minutes at 20-25°C. PERI-GUARD is terminally sterilized using gamma irradiation.

    PERI-GUARD is packaged between two pieces of foam within a double sterile barrier pouch system. The contents of the unopened, undamaged package are sterile.

    AI/ML Overview

    The provided document is a 510(k) premarket notification for two devices: SUPPLE PERI-GUARD Pericardium Patch and PERI-GUARD Repair Patch. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving that the device meets specific acceptance criteria through a comparative effectiveness study with human readers or presenting detailed performance metrics.

    Therefore, the document does not contain the information requested regarding acceptance criteria and a study that proves the device meets those criteria in the context of AI or advanced clinical performance studies.

    Specifically, the document does not include:

    • A table of acceptance criteria and reported device performance in the format requested (likely due to the nature of a 510(k) submission not requiring explicit performance metrics in this way for equivalence).
    • Any details about sample sizes used for a test set, data provenance, ground truth establishment, or expert involvement as typically found in studies for AI/diagnostic devices.
    • Information on adjudication methods.
    • A multi-reader multi-case (MRMC) comparative effectiveness study with effect sizes for human reader improvement with AI.
    • A standalone (algorithm only) performance study.
    • Sample sizes or ground truth establishment for a training set (as this is not an AI/machine learning device).

    Instead, the document focuses on non-clinical testing to demonstrate safety and performance for substantial equivalence. The studies mentioned are:

    1. Bench testing: Assessed aspects like suture retention, thickness, burst strength, ultimate tensile strength, collagenase digestion, chemical residuals, pyrogenicity/LAL, sterilization validation, and packaging/shelf-life. The document states, "Bench testing results support the performance requirements."
    2. Biocompatibility testing: Performed in accordance with ISO 10993-1: 2009.
    3. Animal studies: Conducted to support safety and efficacy.

    These studies are conducted to show the new device is "substantially equivalent" to predicate devices, mainly due to changes in packaging and sterilization methods. The document repeatedly states that the devices (SUPPLE PERI-GUARD and PERI-GUARD) are acting as their own predicates.

    Intended Use

    VASCU-GUARD is intended for use in peripheral vascular reconstruction including the carotid, renal, iliac, femoral, profunda, and tibial blood vessels and arteriovenous access revisions.

    Device Description

    VASCU-GUARD is prepared from bovine pericardium which is cross-linked with glutaraldehyde. VASCU-GUARD has been treated with 1 molar sodium hydroxide for 60-75 minutes at 20-25°C. VASCU-GUARD is terminally sterilized using gamma irradiation.

    AI/ML Overview

    The provided document is a 510(k) premarket notification for a medical device called VASCU-GUARD Peripheral Vascular Patch. It demonstrates substantial equivalence to a predicate device, rather than providing a study proving acceptance criteria for a new AI/software device. Therefore, most of the requested information regarding acceptance criteria, study details, expert involvement, and ground truth for an AI/software device is not applicable to this document.

    However, I can extract information related to the device's performance evaluation and testing, even if it's not in the context of AI/software acceptance criteria.

    Here's an analysis based on the provided text, addressing the applicable points:

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

    The document does not present acceptance criteria in a quantitative table with specific target values and reported performance. Instead, it lists the aspects of the device that were evaluated through non-clinical testing. The conclusion states that "Bench testing results support the performance requirements for VASCU-GUARD Peripheral Vascular Patch," and that the device is "substantially equivalent to the referenced predicate device."

    Evaluated Aspects of Device Performance (from "Summary/Comparison of Technological Characteristics"):

    Evaluated AspectReported Performance (Qualitative)
    Suture retentionBench testing results support performance requirements.
    ThicknessBench testing results support performance requirements.
    Burst strengthBench testing results support performance requirements.
    Tensile strengthBench testing results support performance requirements.
    Collagenase digestionBench testing results support performance requirements.
    Chemical residualsBench testing results support performance requirements.
    Pyrogenicity/ LALBench testing results support performance requirements.
    Sterilization validationBench testing results support performance requirements. Packaging and method of sterilization are the subject of this submission.
    Packaging and shelf-lifeBench testing results support performance requirements. Packaging and method of sterilization are the subject of this submission.
    BiocompatibilityPerformed according to ISO 10993-1:2009. Biocompatibility indicates the device is biocompatible.
    Animal studiesVarious animal studies conducted to support safety and efficacy. Studies indicate the device is safe and efficacious.

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

    • Sample Size: The document does not specify exact sample sizes for each bench test or animal study. It mentions "various animal studies" without quantification.
    • Data Provenance: Not specified. The studies are non-clinical (bench testing and animal studies), not human data, so "country of origin of the data" or "retrospective/prospective" in the human data sense are not directly applicable. These are likely internal laboratory/pre-clinical study results.

    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 is not applicable to the non-clinical testing described. This type of information would be relevant for clinical studies involving expert interpretation of medical images or patient outcomes, which are not detailed here.

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

    Not applicable. Adjudication methods are typically used in clinical studies with human assessors to establish a consensus ground truth, which is not what is being described for these non-clinical tests.

    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 document pertains to a physical medical device (vascular patch) and its non-clinical performance, not an AI or software device that assists human readers.

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

    Not applicable. This is not an AI algorithm.

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

    For the non-clinical tests, the "ground truth" would be established by the specifications and measurement standards for each test (e.g., specific force required for suture retention, material integrity under enzymatic digestion, absence of pyrogens in LAL test, histological findings from animal studies). These are objective measurements against predefined standards, and the "ground truth" is inherent in the test methodology and expected outcomes.

    8. The sample size for the training set

    Not applicable. This is not an AI/machine learning device that requires a training set.

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

    Not applicable. This is not an AI/machine learning device.

    Intended Use

    The Flow COUPLER Device is a single use, implantable device that is intended to be used in the end-to-end anastomosis of veins and arteries normally encountered in microsurgical and vascular reconstructive procedures. The Flow COUPLER Device includes a pair of permanently implanted rings which secure the anastomosis and a removable Doppler probe that is press-fit onto one of the rings. When the Flow COUPLER Device is used in conjunction with the Flow COUPLER Monitor, the Flow COUPLER System is intended to detect blood flow and confirm vessel patency intraoperatively and post-operatively at the anastomotic site. Post-operatively, blood flow can be detected on an as needed basis for up to 7 days. The Flow COUPLER Doppler probe is not intended to be a permanent implant and should be removed 3 to 14 days post-operatively.

    AI/ML Overview

    The provided text describes the GEM™ Flow COUPLER™ Device and System, which is a medical device for microvascular reconstruction procedures. However, the document is a 510(k) premarket notification decision letter from the FDA, and it focuses on demonstrating substantial equivalence to a predicate device, not on proving that the device meets specific acceptance criteria through a clinical study or AI model performance evaluation.

    Therefore, the requested information categories regarding acceptance criteria, device performance, sample sizes, ground truth establishment, expert involvement, adjudication, and MRMC/standalone studies cannot be fully provided based on the given document.

    The document indicates that this device is an update to an existing device (K132727 and K093310). The "acceptance criteria" discussed are largely related to ensuring the new version retains the safety and effectiveness of the previous version and that manufacturing and design changes (like an extended size range) do not negatively impact performance.

    Here's a breakdown of what can be extracted and what cannot:

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

    The document does not provide a table of acceptance criteria and reported device performance in the context of an AI model or a specific clinical trial outcome (e.g., sensitivity, specificity, AUC). Instead, it discusses the validation of functional specifications for a line extension.

    Acceptance Criteria Category (Implied)Reported Device Performance/Testing
    Functional Specifications (3.5mm Flow COUPLER line extension)Bench testing performed to validate that functional specifications were not affected by the line extension.
    Shock and VibrationTested
    Pin Alignment (visual)Tested
    Ring RetentionTested
    Probe SignalTested
    Ring SeparationTested
    Probe to COUPLER separation forceTested
    Risk AssessmentDesign FMEA and Health Hazard Analysis conducted in accordance with EN ISO 14971:2012.
    Overall EquivalenceDevice demonstrated substantial equivalence to the predicate device with respect to biocompatibility, manufacturing process, product performance, indications, sterilization, shelf life, packaging, and safety and efficacy.

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

    Not applicable. The document discusses "bench testing" for a device line extension, not a test set for an algorithm or a clinical study. No information on sample size or data provenance in this context is 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)

    Not applicable. This is not a study involving expert-established ground truth for a test set.

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

    Not applicable. This is not a study involving an adjudicated test set.

    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

    No. This document does not mention an MRMC study or AI models. It pertains to a physical medical device.

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

    No. This document does not discuss an algorithm or standalone performance.

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

    For the bench testing, the "ground truth" would be the engineering specifications and expected performance benchmarks for each test (e.g., a certain force for probe separation, a clear probe signal). For the risk assessment, it would be the identified hazards and their severities. This is not clinical ground truth.

    8. The sample size for the training set

    Not applicable. This document does not describe a training set for an AI model.

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

    Not applicable. This document does not describe a training set for an AI model.

    In summary: The provided text is a regulatory clearance document for a medical device (GEM™ Flow COUPLER™ Device and System) based on substantial equivalence. It details manufacturing, design, and functional testing to support modifications to an existing device, rather than providing the kind of performance data usually associated with acceptance criteria for a new AI-powered diagnostic or prognostic tool.

    AI/ML Overview

    Here's a breakdown of the acceptance criteria and study information based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    The provided text does not explicitly state specific quantitative acceptance criteria or a direct performance table. Instead, it focuses on demonstrating substantial equivalence to a predicate device by verifying that modifications did not affect functional specifications and that the device meets relevant standards.

    However, based on the types of testing performed, we can infer the performance areas that would have had internal acceptance criteria:

    Performance AreaInferred Acceptance Criteria (Not explicitly stated, but implied by testing)Reported Device Performance (Summary from text)
    Doppler Probe Signal FunctionalitySignal should be detectable and accurate for blood flow.Testing included "Doppler probe signal functionality." The submission concludes that "functional specifications were not affected by the modification to the Doppler wire." The system is designed for "detection of blood flow and confirmation of vessel patency." An audible ultrasonic signal is produced when blood flow is detected. The device can detect blood flow for up to 7 days post-operatively.
    Doppler Probe Wire Tensile StrengthWire should withstand specified tensile forces without breaking.Testing included "Doppler probe wire tensile and connection strength testing." The submission concludes that "functional specifications were not affected by the modification to the Doppler wire."
    Doppler Probe Wire Connection StrengthConnections should remain secure under specified forces.Testing included "Doppler probe wire tensile and connection strength testing." The submission concludes that "functional specifications were not affected by the modification to the Doppler wire."
    Electrical Safety (IEC 60601-1 Conformance)Device should meet all applicable electrical safety standards.Testing included "electrical testing conformance to IEC 60601-1." The submission indicates this testing was successful in showing functional specifications were not affected.
    Biocompatibility (ISO 10993-1)Device materials should not cause adverse biological reactions."Biocompatibility testing was performed in accordance to ISO 10993-1." The submission states that "biocompatibility... of this device demonstrates that the device is substantially equivalent to the predicate device."
    Risk Management (EN ISO 14971:2012)Risks should be identified, analyzed, and mitigated to acceptable levels."A risk assessment of the modifications in the form of a Design FMEA and Health Hazard Analysis has been conducted in accordance with EN ISO 14971: 2012." The successful completion of this indicates risks are managed.

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

    • Sample Size for Test Set: The document does not specify a sample size for the non-clinical testing performed. It refers to "testing" performed to verify functional specifications.
    • Data Provenance: The data provenance is not explicitly stated beyond being "non-clinical testing on the modified device." There's no mention of country of origin or whether it was retrospective or prospective, though "non-clinical" usually implies laboratory or bench testing rather than human clinical trials.

    3. Number of Experts and Qualifications for Ground Truth

    • The document does not refer to experts establishing ground truth for any test set in the context of this 510(k) submission. The testing described is primarily engineering and materials-based to confirm functional specifications and safety, not related to expert interpretation of diagnostic output.

    4. Adjudication Method for the Test Set

    • Not Applicable: Since no human interpretation or diagnostic ground truth establishment is described, no adjudication method is mentioned or relevant.

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

    • No: The document does not mention or describe an MRMC comparative effectiveness study. This submission is for a device that detects blood flow, not an imaging or diagnostic algorithm that would typically involve human readers.

    6. Standalone (Algorithm Only) Performance Study

    • The device being submitted (GEM Flow COUPLER) is a hardware device (coupler with an integrated Doppler probe and a monitor unit). While the monitor unit processes the Doppler signal, the submission focuses on the device's functional specifications and safety. Therefore, a standalone "algorithm only" performance study, as typically understood for AI/software, is not applicable to this type of device and is not mentioned. The "detection of blood flow" is an inherent function of the Doppler technology, not a distinct AI algorithm.

    7. Type of Ground Truth Used

    • The ground truth for the non-clinical testing appears to be based on engineering specifications and established regulatory standards. For example, for "Doppler probe signal functionality," the ground truth would be the expected and accurate detection of a simulated or actual blood flow signal. For electrical safety, the ground truth is conformance to IEC 60601-1 standards. For biocompatibility, it's conformance to ISO 10993-1. These are not typically "expert consensus," "pathology," or "outcomes data" in the diagnostic sense.

    8. Sample Size for the Training Set

    • Not Applicable / Not Mentioned: This device is not an AI/ML algorithm that requires a training set in the conventional sense. The "training" of the device is through its design, manufacturing to specifications, and calibration, not through data input.

    9. How Ground Truth for the Training Set was Established

    • Not Applicable / Not Mentioned: As this is not an AI/ML device with a training set, the concept of establishing ground truth for a training set does not apply.
