    Intended Use

    The Twin-Pass OTW Catheter is to be used in conjunction with steerable guidewires in order to access discrete regions of the coronary and peripheral arterial vasculature, to facilitate placement of guidewires and other interventional devices, for use during two guidewire procedures and to subselectively infuse/deliver diagnostic or therapeutic agents.

    Device Description

    The Vascular Solutions Twin-Pass OTW Catheter is a sterile single use device designed for use in the arterial vasculature. The catheter provides support for 0.014"/0.36mm guidewires during interventional procedures, and the dual lumen design allows for the delivery of a second guidewire, contrast, or medication into distal vasculature while leaving the initial guidewire in place.

    AI/ML Overview

    The provided 510(k) summary is for a medical device (Twin-Pass™ OTW Dual Access Catheter) and does not describe an AI/ML powered device or a study involving such a device. Therefore, most of the requested information regarding AI/ML device performance, ground truth, expert adjudication, training/test sets, and MRMC studies is not applicable.

    Here's the information that can be extracted from the provided text:

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

    The document does not explicitly state "acceptance criteria" with numerical targets for each test. Instead, it lists the non-clinical tests conducted and states that "The results of this testing confirmed the suitability of the Twin-Pass OTW Catheter for its intended use."

    The non-clinical tests performed are:

    Acceptance Criteria CategoryReported Device Performance
    TortuosityConfirmed suitability for intended use
    Catheter Kink ResistanceConfirmed suitability for intended use
    Radiopaque MarkerbandConfirmed suitability for intended use
    Hub-to-proximal-shaft Bond StrengthConfirmed suitability for intended use
    Proximal-to-distal-shaft Bond StrengthConfirmed suitability for intended use
    Fluid Leak Under PressureConfirmed suitability for intended use
    Air Leak During AspirationConfirmed suitability for intended use
    Flow Rate (Infuse and Distal Lumen)Confirmed suitability for intended use
    Infuse Lumen Flow RateConfirmed suitability for intended use
    Guidewire InterfaceConfirmed suitability for intended use
    Guide Catheter InterfaceConfirmed suitability for intended use

    2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    This information is not provided. The document mentions "testing conducted," but does not specify sample sizes for these tests, nor the provenance of any data (as it's non-clinical bench testing).

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

    Not applicable. This is not an AI/ML device, and no human "experts" were used to establish ground truth for clinical performance; the testing was non-clinical bench testing.

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

    Not applicable. This is not an AI/ML device, and no human adjudication was involved in the bench testing.

    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 clinical testing was conducted, and 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. This is not an AI/ML device.

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

    For the non-clinical testing, the "ground truth" would be established by engineering specifications, physical measurements, and industry standards for catheter performance (e.g., flow rate measurements, kink resistance thresholds). The document simply states that the tests "confirmed the suitability."

    8. The sample size for the training set

    Not applicable. This is not an AI/ML device, so there is no training set.

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

    Not applicable. This is not an AI/ML device, so there is no training set or associated ground truth establishment process.
