    AI/ML Overview

    The provided document is a 510(k) summary for the CryoValve® SG Pulmonary Valve and CryoValve® SG Pulmonary Valve and Conduit, a human heart valve. It describes the device, its intended use, and substantial equivalence to predicate devices. However, this document does not contain any information regarding acceptance criteria, device performance, a study to prove acceptance criteria, sample sizes, ground truth establishment, or expert involvement as typically required for AI/ML device evaluations.

    The "Analysis Supporting Substantial Equivalence" section states: "A Clinical Data Analysis provides the needed assessment to support the product claim. The Analysis reviews A Cinnell Dall Analysis provides the necesses scientific rationale needed to make this change to the labeling." This vague statement implies a clinical data analysis was performed, but no details of this analysis are provided in the document. The document primarily focuses on regulatory clearance based on substantial equivalence to a previously cleared predicate device (K033484).

    Therefore, I cannot provide the requested information for the following points as they are not present in the provided text:

    1. A table of acceptance criteria and the reported device performance: Not available. The document is about a heart valve, not an AI/ML device with performance metrics like sensitivity/specificity.
    2. Sample size used for the test set and the data provenance: Not available.
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not available.
    4. Adjudication method for the test set: Not available.
    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 as this is not an AI/ML device.
    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable as this is not an AI/ML device.
    7. The type of ground truth used: Not available.
    8. The sample size for the training set: Not available.
    9. How the ground truth for the training set was established: Not available.

    The document is a regulatory submission for a medical device (human heart valve) which is substantially different from an AI/ML software device that would typically undergo performance evaluation against specific acceptance criteria.

    AI/ML Overview

    The provided text describes a 510(k) summary for the CryoValve® SG Pulmonary Valve and Conduit, a human heart valve allograft. However, the document does not contain information regarding
    acceptance criteria
    in the way it is typically described for an AI/ML medical device. Instead, it focuses on demonstrating substantial equivalence to a predicate device through preclinical bench, animal testing, and clinical evaluation.

    Therefore, many of the requested categories for acceptance criteria and study details cannot be filled from the provided text, as this medical device is a human tissue allograft, not an AI/ML driven device.

    Here's an analysis based on the information available:

    1. Table of Acceptance Criteria and Reported Device Performance:

    Acceptance CriteriaReported Device Performance
    Not applicable for this type of device in the context of AI/ML or specific quantitative performance metrics like sensitivity/specificity.CryoValve SG was found to be comparable to the predicate CryoValve in terms of biocompatibility, integrity, and mechanical performance. This comparability provides reasonable assurance of device performance for its intended use and supports a determination of substantial equivalence.

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

    • Sample Size (Test Set): Not specified in the provided document. The clinical evaluation is mentioned, but no details on sample size are given.
    • Data Provenance: Not specified. The document mentions "clinical evaluation" but doesn't detail the nature, retrospective/prospective design, or geographic origin of the data.

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

    • Number of Experts: Not applicable/not specified. The "ground truth" for this device would likely be derived from a combination of clinical outcomes, histological analysis (for biocompatibility), and mechanical testing, rather than expert consensus on diagnostic images.
    • Qualifications of Experts: Not applicable/not specified.

    4. Adjudication method for the test set:

    • Not applicable/not specified.

    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 is not an AI/ML device, so an MRMC study related to AI assistance is not relevant.

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

    • No. This is not an AI/ML device.

    7. The type of ground truth used:

    • Based on the general context of medical device approval for allografts, the "ground truth" or evidence demonstrating safety and effectiveness would likely include:
      • Clinical Outcomes Data: From the "clinical evaluation" mentioned, demonstrating patient outcomes after implantation.
      • Biocompatibility Testing: Ensuring the material does not cause adverse biological reactions.
      • Integrity and Mechanical Performance Testing: Bench and animal testing to assess the structural soundness and functional performance of the valve under simulated physiological conditions.
      • Histological and Microbiological Analysis: To confirm tissue quality, cell removal, and sterility.

    8. The sample size for the training set:

    • Not applicable. This is not an AI/ML device. The "training" here would refer to the historical data and experience with the predicate device (CryoValve) rather than a defined training set for an algorithm.

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

    • Not applicable. Any "ground truth" related to the predicate device would have been established through its own preclinical and clinical evaluations, which preceded this 510(k) submission. The current submission focuses on demonstrating comparability between the new device and the existing predicate.
