    Device Description

    Ablation wands are indicated for resection, ablation, and coagulation of soft tissue, and hemostasis of blood vessels in arthroscopic procedures, including knee, shoulder, ankle, hip, elbow, and wrist joints. The device is powered by a separate generator. The generator is not included in the scope of the study and will not be reprocessed.

    AI/ML Overview

    This document is a 510(k) premarket notification for reprocessed electrosurgical cutting and coagulation devices. It details the substantial equivalence determination made by the FDA. The document does not describe the acceptance criteria and study for a medical device's performance in the context of AI/ML or clinical efficacy, but rather focuses on the substantial equivalence of reprocessed medical devices to predicate devices.

    Therefore, most of the requested information regarding acceptance criteria, performance metrics, sample sizes for test and training sets, expert qualifications, and adjudication methods (as typically applied to AI/ML device evaluations) are not applicable to this type of submission.

    However, I can extract information related to the performance testing conducted to demonstrate substantial equivalence for the reprocessed devices:

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

    The document describes various performance tests conducted to demonstrate equivalence to the predicate devices. It doesn't present a table of specific acceptance criteria values alongside reported device performance values in the way one would for a novel device's clinical efficacy. Instead, it lists the types of tests performed and states that the devices were "found to be equivalent."

    Type of TestReported Device Performance
    Sterilization validationFound to be equivalent to the predicate devices
    BiocompatibilityFound to be equivalent to the predicate devices
    Cytotoxicity, sensitization, irritationFound to be equivalent to the predicate devices
    Pyrogenicity, and acute systemic toxicityFound to be equivalent to the predicate devices
    Electrical testingFound to be equivalent to the predicate devices
    Electromagnetic compatibility (per IEC 60601-1-2)Found to be equivalent to the predicate devices
    Electrical safety (per IEC 60601-1 and IEC 60601-2-2)Found to be equivalent to the predicate devices
    Basic safety (per IEC 60601-1 and IEC 60601-2-2)Found to be equivalent to the predicate devices
    Performance qualification: simulated useFound to be equivalent to the predicate devices
    Performance qualification: critical function bending equivalence testFound to be equivalent to the predicate devices
    Performance qualification: critical function suction equivalence testFound to be equivalent to the predicate devices
    Performance qualification: critical function thermal tissue damage equivalence testFound to be equivalent to the predicate devices
    Performance qualification: critical function drop equivalence testFound to be equivalent to the predicate devices
    Performance qualification: critical function device equivalence integrityFound to be equivalent to the predicate devices
    Performance qualification: product stabilityFound to be equivalent to the predicate devices
    CleaningFound to be equivalent to the predicate devices
    Protein, and hemoglobin (residue testing)Found to be equivalent to the predicate devices

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

    The document does not specify the sample sizes used for each of the performance tests listed. The data provenance is implied to be from laboratory testing performed by Surgical Instrument Service and Savings Inc. (dba Medline ReNewal) as part of their reprocessing validation, conducted in the United States. It's retrospective in the sense that the studies are conducted after the reprocessing process is established.

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

    This information is not applicable. For reprocessed devices, "ground truth" refers to the original device's performance characteristics. Equivalence testing compares the reprocessed device to the original (predicate) specifications, not human expert interpretation.

    4. Adjudication method for the test set:

    This information is not applicable. Adjudication methods like 2+1 or 3+1 are typically used for clinical studies involving human interpretation or subjective assessments. The tests described are objective engineering and performance validations.

    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:

    This information is not applicable. This document concerns reprocessed electrosurgical tools, not AI/ML-assisted diagnostic or interpretive devices. No MRMC studies were conducted.

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

    This information is not applicable. This document does not describe an AI/ML algorithm.

    7. The type of ground truth used:

    The "ground truth" in this context is the established performance specifications and safety profiles of the original, legally marketed predicate devices. The reprocessed devices are evaluated against these known characteristics to demonstrate that they perform "as good as" the original devices.

    8. The sample size for the training set:

    This information is not applicable. There is no "training set" in the context of validating reprocessed physical medical devices.

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

    This information is not applicable. As there is no training set, there is no ground truth to establish for it in this context.
