    Intended Use

    The Quantum TTC Biliary Balloon Dilator is used to dilate strictures of the biliary tree.

    Device Description

    The subject balloon dilator is a 3 cm polyethylene terephthalate (PET) balloon mounted at the distal end of pebax catheter. The balloon can be inflated to single size diameters of 4, 6, 8, or 10 mm. The catheter is available in lengths of 180 cm or 320 cm with a 6.8-5.5 Fr diameter.

    AI/ML Overview

    This is a 510(k) summary for the Quantum TTC Biliary Balloon Dilator. It describes device performance through non-clinical testing rather than clinical study. Therefore, several aspects of your request, such as sample size for test/training sets, expert qualifications, adjudication methods, MRMC studies, standalone performance, and ground truth types related to a clinical study, are not applicable or cannot be extracted from this document.

    Here's the information that can be extracted or inferred from the provided document regarding acceptance criteria and performance:

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

    The document lists various non-clinical tests performed to demonstrate device performance. The specific acceptance criteria (e.g., "balloon must burst above X psi") are not explicitly stated with numerical values; only the categories of tests are provided. However, the conclusion states that these tests confirm the device performs as intended and adequately address risks, implying that acceptance criteria for each test were met.

    Acceptance Criteria Category (Test Performed)Reported Device Performance
    Balloon Diameter and LengthPerformed as intended
    DistensibilityPerformed as intended
    Balloon Burst StrengthPerformed as intended
    Tensile Testing of the Device Joint ComponentsPerformed as intended
    Radiopacity TestingPerformed as intended
    Dimensional Testing Through Simulated UsePerformed as intended
    Shelf Life TestingPerformed as intended
    Packaging ValidationPerformed as intended
    Biocompatibility TestingPassed according to ISO 10993-1

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

    • Sample Size for Test Set: Not applicable. This document reports on non-clinical (engineering and laboratory) testing rather than a clinical study with human subjects. The "test set" would refer to the number of devices or components tested, which is not specified.
    • Data Provenance: The testing was conducted internally by the manufacturer (Wilson-Cook Medical, Inc.) as part of their design verification and validation process. This is internal testing, not data from a specific country or retrospective/prospective clinical study.

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

    Not applicable. Ground truth, in the context of clinical studies, refers to the confirmed diagnosis or outcome used to evaluate a device's accuracy. This document describes non-clinical engineering tests. The "ground truth" for these tests would be established by engineering specifications and standards, not expert clinical consensus.

    4. Adjudication method for the test set

    Not applicable. Adjudication methods like '2+1' are used in clinical studies to resolve discrepancies among experts. This is not relevant for non-clinical engineering tests.

    5. If a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done

    No, an MRMC comparative effectiveness study was not done. This document focuses on non-clinical performance to confirm substantial equivalence through engineering tests.

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

    Not applicable. This device is a physical medical instrument (a balloon dilator), not an algorithm or AI-based device. Therefore, the concept of "standalone performance" in the context of algorithms does not apply. The device's performance is inherently "standalone" in that it performs its physical function (dilation).

    7. The type of ground truth used

    For the non-clinical tests described, the "ground truth" implicitly refers to engineering specifications, design requirements, and relevant international standards (e.g., ISO 10993-1 for biocompatibility). The device's performance was compared against these predefined physical and material property requirements.

    8. The sample size for the training set

    Not applicable. This is not an AI/machine learning device, so there is no concept of a "training set."

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

    Not applicable, as there is no training set for this type of device.
