    SUPER TORQUE MB Angiographic Catheter with Radiopaque markerbands

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

    Cordis Angiographic Catheters with Marker Bands are designed to provide angiographic visualization and linear measurement of the vasculature when combined with the delivery of radiopaque contrast media to selected sites in the vascular system.

    Device Description

    The SUPER TORQUE® MB Angiographic Catheter is a thin plastic tube which is inserted into an artery through a small incision in the skin. The catheter is guided to the area being examined, and contrast material is injected through the tube and images are captured using a small dose of ionizing radiation (x-rays). Each SUPER TORQUE® MB Angiographic Catheter consists of a braided Polyurethane body and a non-braided Polyurethane tip section having multiple, radiopaque marker bands.

    AI/ML Overview

    This document is a 510(k) Premarket Notification for a medical device called the SUPER TORQUE® MB Angiographic Catheter. It is not an AI/ML device, and therefore the concepts of acceptance criteria and a study to prove the device meets those criteria (in the context of AI/ML performance metrics) do not apply in the traditional sense.

    The document describes a submission seeking substantial equivalence to a legally marketed predicate device (K992347). For such devices, the "acceptance criteria" are generally that the new device is as safe and effective as the predicate device. This is typically demonstrated through a comparison of technological characteristics, and often, non-clinical (bench) testing. Clinical studies are not always required if substantial equivalence can be shown otherwise.

    Here's why the requested information cannot be provided in the context of AI/ML device evaluation:

    • No AI/ML Component: The SUPER TORQUE® MB Angiographic Catheter is a physical medical device (a thin plastic tube for angiography), not a software algorithm or an AI/ML system.
    • No "Performance Metrics" in the AI Sense: The performance of this device is assessed by its physical characteristics, material properties, and functionality (e.g., ability to deliver contrast, radiopacity of marker bands), not by metrics like sensitivity, specificity, AUC, or reader performance improvement often used for AI.
    • No "Training/Test Sets" for AI: The concept of training sets and test sets with ground truth established by experts is irrelevant for a physical catheter.

    However, I can extract and present the available information in a slightly adapted format, focusing on how substantial equivalence was demonstrated, which is the closest analog to "meeting acceptance criteria" for this type of device.


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

    For this physical angiographic catheter, "acceptance criteria" relate to demonstrating substantial equivalence to a predicate device. The performance is assessed through bench testing and comparison of fundamental technological characteristics.

    Acceptance Criterion (for Substantial Equivalence)Reported Device Performance/Comparison
    Intended Use: Same as predicate device.The proposed SUPER TORQUE® MB Angiographic Catheter and the predicate device have the same intended use: to provide angiographic visualization and linear measurement of the vasculature when combined with the delivery of radiopaque contrast media to selected sites in the vascular system. (A new contraindication was added, but the intended use remains the same).
    Technological Characteristics: Same fundamental technology.The device is described as "the same device as that of the currently cleared device" with a new contraindication. Both the proposed and predicate devices are inserted into an artery, contain a luer connector, braided catheter body, and an atraumatic tip. The materials of construction are listed and appear consistent with the predicate's technology.
    Performance: Device meets established performance characteristics."The testing previously conducted, and the additional testing provided in this 510(k) confirm that the SUPER TORQUE® MB Angiographic Catheter meets established performance characteristics." (This refers to bench testing, as detailed below.)
    Safety: Device is as safe as the predicate.Implied through substantial equivalence to a device cleared for safety and effectiveness. Minor manufacturing updates and additional biocompatibility testing were performed (see below).
    Effectiveness: Device is as effective as the predicate.Implied through substantial equivalence.

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

    Not applicable in the context of AI/ML. For a physical device, testing is typically done on manufactured samples. The document states "No new testing was required to be conducted due to addition of contraindication in the IFU." It also mentions "minor manufacturing updates were made, additional biocompatibility testing was performed, and additional sterilization facilities were qualified." This implies some level of physical testing (bench testing) on device samples, but specific sample sizes for these tests are not detailed in this submission. Data provenance would be from laboratory test reports.

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

    Not applicable. This is not an AI/ML device requiring expert adjudication for ground truth.

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

    Not applicable. This is not an AI/ML device requiring expert adjudication.

    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. This is not an AI/ML device. No MRMC study was performed. The document explicitly states: "No clinical data was required in support of the proposed change to the predicate device cleared under K992347."

    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, so there is no algorithm to evaluate in standalone mode.

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

    Not applicable. For a physical device, "ground truth" would be engineering specifications and validated test methods for material properties, dimensions, and mechanical performance.

    8. The sample size for the training set

    Not applicable. This is not an AI/ML device.

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

    Not applicable. This is not an AI/ML device.
