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

    The document does not specify the sample sizes used for each of the performance or biocompatibility tests. It only states that tests were performed on "non-aged and accelerated aged samples" for performance testing (except Radio-detectability and Simulated Use Usability) and on "non-aged, sterile, whole device" and "accelerated-aged (2 years), sterile, whole device" for biocompatibility.

    The data provenance is industrial (manufacturer-conducted testing) and likely combines both novel testing for this specific device and potentially established testing protocols based on industry standards. It is not patient or clinical data, so terms like "retrospective" or "prospective" are not applicable in this context. The country of origin for the manufacturing and testing is Japan (Ashitaka Factory of Terumo Corporation).


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

    This document describes non-clinical performance and biocompatibility testing of a medical device (a microcatheter). It does not involve diagnostic interpretation or patient data where "ground truth" would typically be established by human experts like radiologists. Therefore, this information is not applicable to the provided document. The ground truth for these tests is based on objective, measurable physical and chemical properties and engineering standards.


    4. Adjudication Method for the Test Set

    As this document describes non-clinical performance and biocompatibility testing, an "adjudication method" in the context of expert consensus (like 2+1 or 3+1 for clinical interpretations) is not applicable. The results of these tests are determined by adherence to pre-defined scientific and engineering protocols and acceptance criteria.


    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

    There was no MRMC comparative effectiveness study and no AI component mentioned in this 510(k) submission. This K-submission is for a medical device (microcatheter), not an AI/software-as-a-medical-device.


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

    This is not applicable as the device is a physical medical instrument (microcatheter), not an algorithm or AI system.


    7. The Type of Ground Truth Used (expert concensus, pathology, outcomes data, etc)

    For the performance tests, the "ground truth" is defined by engineering specifications, material science principles, and established industry standards. For example, the freedom from leakage is tested against a standard preventing fluid escape, and material biocompatibility is tested against ISO 10993 standards and FDA guidance. This is not a "ground truth" derived from expert consensus, pathology, or outcomes data in a clinical sense.


    8. The Sample Size for the Training Set

    There is no training set in this context. This is a physical medical device, not a machine learning model.


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

    This is not applicable as there is no training set mentioned in the document.

    AI/ML Overview

    The provided text is a 510(k) summary for the Progreat catheter, which is a medical device. This document focuses on demonstrating substantial equivalence to a previously cleared predicate device, rather than providing a detailed study proving the device meets specific acceptance criteria in the context of an AI/ML-driven medical device.

    Therefore, many of the requested criteria for AI/ML device studies (such as types of ground truth, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance) are not applicable to this document.

    However, I can extract information related to the device's technical specifications and the non-clinical tests performed to assess its performance against predetermined criteria.

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

    The document does not explicitly state the specific sample sizes for each non-clinical test conducted. It mentions that tests were performed on "non-aged and accelerated aged samples." The provenance of the data is from Terumo Corporation's Ashitaka Factory in Japan, where the device is manufactured and where these non-clinical tests were presumably conducted. This is retrospective in the sense that the testing was performed on manufactured devices to support the 510(k) submission.

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

    This information is not applicable as the device is a physical medical instrument, not an AI/ML diagnostic tool requiring expert interpretation for ground truth. Performance was assessed against engineering specifications and industry standards.

    4. Adjudication Method for the Test Set

    This information is not applicable for a physical device's non-clinical performance testing. Adjudication methods like 2+1 or 3+1 typically apply to human interpretation of diagnostic images or data.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

    A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not conducted, and such a study is not applicable for this type of medical device (intravascular catheter). This type of study is relevant for evaluating the impact of AI assistance on human reader performance in diagnostic tasks.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

    A standalone algorithm-only performance assessment was not conducted, as this device is a physical catheter and not an algorithm. This criterion is not applicable.

    7. The Type of Ground Truth Used

    The "ground truth" for the performance tests effectively refers to predetermined engineering specifications, design requirements, and relevant industry standards for intravascular catheters (e.g., ISO standards for medical devices, internal Terumo specifications). The tests confirm if the device meets these established benchmarks.

    8. The Sample Size for the Training Set

    This information is not applicable. The concept of a "training set" applies to machine learning models, not to the manufacturing and testing of a physical medical device.

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

    This information is not applicable for the reasons stated above.
