    Intended Use

    To establish a continuous conduit during urological endoscopic procedures facilitating the in and out passage of endoscopes and other instruments into the urinary tract.

    Device Description

    The Re-Trace Ureteral Access Sheath 10/12 Ch/Fr & Ureteral Access Sheath are line extensions of the Re-Trace Ureteral Access Sheath 12/14 Ch/Fr. All these devices comprise the following components:

    • Reinforced tube/sheath .
    • Introducer/dilator .
    • Connector .
    • Clip .
      The only design addition to the 10/12 Ch/Fr reinforced tube/sheath compared to the 12/14 Cly/Fr sheath is the presence of a reinforcing Stainless Steel ring at the distal tip.
      For the Ureteral Access Sheath, the introducer/dilator also only has a guidewire entry eye at the distal tip compared with guidewire entry and exit eyes and three exit holes for fluid delivery on the Re-Trace Ureteral Access Sheath introducer/dilator.
      Apart from these modifications, all the Re-Trace Ureteral Access Sheath & Ureteral Access Sheath range is very similar in design.
    AI/ML Overview

    The provided text describes a 510(k) summary for the Re-Trace Ureteral Access Sheath. It outlines the device's description, intended use, and a comparison to predicate and reference devices for establishing substantial equivalence. However, it does not include the detailed information requested regarding specific acceptance criteria, study methodologies for device performance, ground truth establishment, or human-in-the-loop studies.

    This submission is for a medical device (Ureteral Access Sheath) which is typically evaluated through non-clinical performance testing and biocompatibility. The type of "acceptance criteria" and "study" described in the input prompt (e.g., sample size, ground truth, expert consensus, MRMC studies) are characteristic of studies evaluating diagnostic accuracy or clinical effectiveness for devices that generate data (like AI/ML algorithms). The Re-Trace Ureteral Access Sheath is a physical medical instrument, not a diagnostic or AI device.

    Therefore, the requested information cannot be fully extracted from the provided text for this specific device.

    Based on the provided text, here's what can be inferred and what information is missing:

    1. Table of Acceptance Criteria and Reported Device Performance:

    Acceptance CriteriaReported Device Performance
    Mechanical Performance:
    Sheath/introducer/ component break force testingSuccessful completion compared to predicate device
    Friction testingSuccessful completion compared to predicate device
    Kink resistance testingSuccessful completion compared to predicate device
    Injection testingSuccessful completion compared to predicate device
    Guidewire pullout force testingSuccessful completion compared to predicate device
    Packaging testingSuccessful completion compared to predicate device
    Biocompatibility:
    ISO 10993 (Biocompatibility)Successful completion on the Re-Trace Ureteral Access Sheath

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

    • Not Applicable / Not Provided: The submission describes non-clinical performance testing and biocompatibility testing, not a clinical study involving a "test set" of patient data.

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

    • Not Applicable / Not Provided: Ground truth as described (e.g., expert consensus on medical images) is not relevant to the non-clinical performance and biocompatibility testing performed for this physical device.

    4. Adjudication method for the test set:

    • Not Applicable / Not Provided: As there is no "test set" in the context of diagnostic accuracy, there is no adjudication method described.

    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 / No: This device is a physical medical instrument, not an AI/ML diagnostic or assistive device. An MRMC study is not relevant to its evaluation.

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

    • Not Applicable / No: This device is not an algorithm or AI system.

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

    • Not Applicable / Not Provided: For the performance tests, the "ground truth" would be engineering specifications and standards for device functionality and material integrity. For biocompatibility, it's compliance with ISO 10993 standards.

    8. The sample size for the training set:

    • Not Applicable / Not Provided: There is no "training set" as this is not an AI/ML device.

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

    • Not Applicable / Not Provided: There is no "training set" for this type of device.

    In summary: The provided document is a 510(k) summary for a physical medical device (Ureteral Access Sheath), not a diagnostic device or an AI/ML product. The evaluation focuses on non-clinical performance testing (e.g., break force, friction, kink resistance) and biocompatibility to demonstrate substantial equivalence to a predicate device. The questions in the prompt, while relevant for AI/ML or diagnostic devices, do not directly apply to the information presented for this type of product.
