    ASAHI PTCA GUIDE WIRE, J SHAPE SERIES

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    To facilitate the placement of ballon dilation Catheters during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA). The Asahi PTCA Guide Wire, J Shape series is not to be used in the cerebral vasculature.

    Device Description

    The Asahi PTCA Guide Wire, ] Shape series is steerable guide wire with a maximum diameter of 0.014" and available in 180 cm and 300 cm length. The extension wire is connected to the end of the guide wire ourside the body. The wire is constructed from a stainless steel core with varying core lengths and diameter for each design. The core wre and coil are soldered, for some items welding is used for up parts instead of soldering. The distal end of the guide wire has a radiopaque up that is available as a pre shaped ""[" and is made soft to easily bend with the vessel curve. The coanng (hydrophilic and silicone) is applied to the distal portion of the wire guide wire. The proximal section of the guide wire is coated with PTFE. H on the product code indicates hydrophilic coating, and J indicates pre shaped "J" tip of the guide wire.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for the Asahi PTCA Guide Wire, J Shape series, and focuses on establishing substantial equivalence to predicate devices, rather than a study proving specific acceptance criteria for a new AI/software device. Therefore, much of the requested information (like AI-specific criteria, sample sizes for test/training sets for AI, expert adjudication, MRMC studies, standalone performance, and ground truth for AI) is not applicable or present in this document.

    However, I can extract the relevant information regarding the device's acceptance criteria and the study performed, framed within the context of a medical device submission:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria CategoryReported Device Performance
    Bench TestingMet acceptance criteria
    Biocompatibility TestingMet acceptance criteria
    Performance SimilarityPerformed similarly to predicate devices

    Explanation: The document states that "Bench and biocompatibility testing were conducted according to the recommendations from relevant FDA guidance to demonstrate that the Asahi PTCA Guide Wire, J Shape series met the acceptance criteria and performed similarly to the predicate devices." It also explicitly mentions that "No new safety or effectiveness issues were raised during the testing."

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

    This information is not provided in the document. The document refers to "bench and biocompatibility testing" but does not specify the sample sizes used for these tests or the data provenance (e.g., country of origin, retrospective/prospective).

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

    This information is not applicable as the document describes a physical medical device (guide wire) and its performance, not an AI/software device requiring expert-established ground truth for a test set.

    4. Adjudication Method for the Test Set

    This information is not applicable as the document describes a physical medical device and its performance, not an AI/software device requiring an adjudication method for a test set.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and its Effect Size

    This information is not applicable as the document describes a physical medical device and its performance, not an AI/software device that would typically undergo an MRMC study.

    6. If a Standalone (algorithm only without human-in-the-loop performance) was done

    This information is not applicable as the document describes a physical medical device, not an algorithm.

    7. The Type of Ground Truth Used

    The "ground truth" for the device's performance was established through bench testing (evaluating physical properties and functions against predefined specifications) and biocompatibility testing (evaluating biological safety according to established standards). These tests inherently define the "truth" of whether the device meets its design and safety requirements.

    8. The Sample Size for the Training Set

    This information is not applicable as the document describes a physical medical device, not an AI/software device that requires a training set.

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

    This information is not applicable as the document describes a physical medical device, not an AI/software device that requires a training set and its associated ground truth establishment.
