    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria CategorySpecific Criteria/StandardReported Device Performance
    BiocompatibilityISO 10993-1, ISO 10993-5, ISO 10993-10, and ISO 10993-11 (for External Communicating Devices: Tissue/Bone/Dentin with limited contact duration <24 hours)Cytotoxicity, Intracutaneous Reactivity, Sensitization, and Acute Systemic Toxicity tested. All acceptance criteria of the standards were met through testing or justified through risk assessment.
    Sterilization ValidationISO 17665-1 (for Pre-vacuum steam sterilization cycles of 132°C for 4 minutes and 134°C for 3 minutes)Testing was done to validate common cycles to achieve a Sterility Assurance Level of 10⁻⁶.
    Electrical SafetyANSI/AAMI ES60601-1 (General Requirements for Basic Safety and Essential Performance) and IEC 60601-2-2 (Particular Requirements for the Basic Safety and Essential Performance of High Frequency Surgical Equipment and High Frequency Surgical Accessories)The proposed devices comply with these standards for safety.
    Mechanical TestingNot explicitly stated, but included testing for shaft deflection and electrical safety after simulated use.Reliability testing was conducted, including shaft deflection and electrical safety after simulated use. (Implied to have met performance needs for substantial equivalence).

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

    The provided document does not specify sample sizes for any of the testing conducted (biocompatibility, sterilization, electrical safety, mechanical testing).

    The data provenance is not explicitly stated beyond the testing being performed in support of the substantial equivalence determination for the device. Given the context of a 510(k) submission, this typically refers to testing conducted by the manufacturer or a contracted lab under their direction, likely within the US, but this is an inference. It is retrospective in the sense that the testing was performed on completed device designs to demonstrate compliance, rather than in a prospective clinical trial.

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

    This document describes pre-market testing for a medical device (laparoscopic handle). These types of tests (biocompatibility, sterilization, electrical safety, mechanical) do not typically involve human experts establishing "ground truth" in the way it's understood for AI/diagnostic studies. The "ground truth" here is defined by compliance with established scientific standards and regulatory requirements. The experts involved would be the testers and engineers conducting the studies, and potentially external auditors or consultants specializing in those regulatory standards. Their qualifications would be in their respective fields (e.g., microbiology for sterilization, toxicology for biocompatibility, electrical engineering for safety, mechanical engineering for mechanical testing). No specific number or qualifications of such experts are provided in this document.

    4. Adjudication Method for the Test Set

    As mentioned above, the tests are primarily objective measurements against established standards, not subjective assessments requiring adjudication. Therefore, no adjudication method like 2+1 or 3+1 is applicable or mentioned for the described testing. The assessments are based on whether predefined metrics (e.g., bacterial kill rate, material toxicity, electrical leakage) meet specified limits.

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

    No MRMC comparative effectiveness study was done or is mentioned. This type of study is typically performed for diagnostic or AI-assisted interpretation devices to compare human performance with and without AI. This device is a surgical instrument handle, not an interpretive medical device.

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

    N/A. This device is a manual surgical instrument handle, not an algorithm or AI system.

    7. The Type of Ground Truth Used

    The "ground truth" for the performance assessment of this ergonomic handle is defined by:

    • Compliance with recognized international and national standards: ISO 10993 series (biocompatibility), ISO 17665-1 (sterilization), ANSI/AAMI ES60601-1 and IEC 60601-2-2 (electrical safety).
    • Engineering specifications and test protocols: for mechanical reliability (shaft deflection, electrical safety after simulated use).
    • Demonstration of substantial equivalence to a predicate device (K150127) through comparing technological characteristics and ensuring no new issues of safety or effectiveness are raised.

    8. The Sample Size for the Training Set

    N/A. This device is a physical surgical instrument, not an AI/machine learning system, so there is no "training set."

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

    N/A. Since there is no training set, this question is not applicable.

    2. Sample size used for the test set and the data provenance:
    The document does not specify numerical sample sizes for the test set for its performance studies (sterilization efficacy, shelf life, reuse testing, biocompatibility, or functional strength).
    The data provenance is not explicitly mentioned as a country of origin or whether it's retrospective or prospective; however, the submission is from "Symmetry Surgical, Inc." which is based in Antioch, TN, USA, suggesting the studies likely occurred in the US. The studies are described as "performance testing" and "non-clinical tests," implying they were conducted specifically for this submission, making them prospective in nature for this application.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
    This information is not provided in the document. The studies are described as laboratory-based performance testing rather than studies requiring expert interpretation of results for ground truth establishment (e.g., medical image analysis).

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

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
    The ground truth for the performance studies appears to be based on objective, measurable criteria derived from scientific and engineering principles for sterilization, material integrity, and functionality. For instance, "sterilization efficacy" ground truth is defined by achieving a specified Sterilization Assurance Level (SAL of 10-6), which is typically confirmed through validated microbiological testing (e.g., biological indicators). Shelf life is determined by maintaining sterility over time, also verified through microbiological methods. Biocompatibility relies on established in vitro evaluation standards.

    8. The sample size for the training set:
    This information is not applicable and therefore not provided in the document. The product is a physical device, not a machine learning model, so there is no "training set."

    9. How the ground truth for the training set was established:
    This information is not applicable as there is no training set for this type of device.

    Intended Use

    The Bookwalter Gordon Adjustable Compression Element is indicated for use to provide hemostasis of the femoral vascular access site, during and following catheterization or cannulation procedures.

    Device Description

    The Bookwalter Gordon Adjustable Compression Element is an adjustable metal compression device that provides an alternative to applying direct hand pressure to obtain hemostasis during vascular catheterization procedures. The device is secured to a surgical table by means of a compatible clamp which supports an articulating arm that allows positioning of the "metal hand" over the vascular access site. The hand has "fingers" that can be adjusted separately to apply compressive pressure to particular locations around the vascular access site. Once in place the Adjustable Compression Element remains securely in position thereby providing ongoing compression without intervention by the surgical staff although it can be adjusted at any time if so desired. The device is reusable and can be cleaned and sterilized in the hospital setting. The Adjustable Compression Element is constructed of high strength stainless steel for rigidity and durability during use. The system also has an available sterilization container to ensure effective reprocessing.

    • Sample Size for Test Set: Not explicitly stated. The document refers to "Performance testing consisting of cut testing, foot load plate testing, cycle testing and corrosion resistance." The number of devices or components tested in these non-clinical tests is not provided.
    • Data Provenance: Not applicable in the context of clinical data for diagnostic or AI/ML devices. The testing is internal non-clinical performance testing.

    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. This is not a study requiring expert interpretation or ground truth establishment in the traditional sense of a clinical or image-based diagnostic study. The "ground truth" here is the physical performance of the device against engineering specifications.
    • Qualifications of Experts: Not applicable.

    4. Adjudication Method for the Test Set

    • Adjudication Method: Not applicable. This is not a study requiring subjective interpretation or adjudication. The performance tests are objective mechanical or material 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

    • MRMC Study: No. This is a surgical instrument, not a diagnostic imaging device, and does not involve AI assistance or human readers.

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

    • Standalone Performance: Not applicable. This is a manual surgical instrument, not an algorithm or AI device.

    7. The Type of Ground Truth Used

    • Type of Ground Truth: The "ground truth" in this context would be the engineering specifications and performance benchmarks derived from the predicate devices or industry standards for similar instruments. The tests performed ("cut testing, foot load plate testing, cycle testing and corrosion resistance") are designed to verify that the device meets these physical and functional requirements.

    8. The Sample Size for the Training Set

    • Sample Size for Training Set: Not applicable. There is no machine learning or AI component requiring a training set.

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

    • Ground Truth for Training Set: Not applicable. There is no machine learning or AI component requiring a training set.
