    BARD NO-RINSE HEMOCONCENTRATOR AND ACCESSORY KIT

    Intended Use

    The Bard® No-rinse Hemoconcentrator is intended for the relief or mitigation of overhydration in patients undergoing cardiopulmonary procedures and to increase the concentration of cells and proteins in the blood.

    Device Description

    The Bard No-rinse Hemoconcentrator and accessory kit for hemoconcentration serve the needs of cardiopulmonary procedures. Connected to the external cardiopulmonary blood circuit, the hemoconcentrator generates ultrafiltrate with electrolyte and solute compositions similar to that of plasma water. The Bard' No-rinse Hemoconcentrators are made of glycerin-free polysulphone membranes. The no-rinse feature provides convenience of inserting the device into the external cardiopulmonary blood circuit without the need to rinse the device.

    AI/ML Overview

    The provided text describes a 510(k) summary for the Bard® No-rinse Hemoconcentrator and Accessory Kit, HC40TS. This type of submission relies on demonstrating substantial equivalence to a predicate device, rather than conducting a full-scale clinical study with acceptance criteria and statistical proof of meeting those criteria in the way an AI/ML device would.

    Therefore, many of the requested items (sample size, expert qualifications, adjudication, MRMC studies, standalone performance, ground truth establishment) are not applicable to this type of device submission as they were not part of the required evaluation.

    However, I can extract the information relevant to how the device's performance was evaluated for substantial equivalence.

    1. Table of Acceptance Criteria and Reported Device Performance

    For this 510(k) submission, "acceptance criteria" are implied by the performance of the predicate devices. The new device must perform in a "substantially equivalent" manner. There aren't explicit numerical acceptance criteria stated, but rather a comparison to established devices.

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

    • Test Set Sample Size: Not explicitly stated as a "test set" in the context of an AI/ML device. Performance testing was conducted to show substantial equivalence to predicate devices. The number of units or tests performed for each characteristic (cell damage, protein analysis, etc.) is not specified.
    • Data Provenance: The document does not specify the country of origin or whether the data was retrospective or prospective. It describes laboratory/bench testing ("performance testing") rather than patient data.

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

    Not applicable. This is a medical device (hemoconcentrator), not an AI/ML diagnostic or prognostic system requiring expert-established ground truth on a test set. Evaluation relies on physical and functional performance testing.

    4. Adjudication method for the test set

    Not applicable. As above, this is not an AI/ML system 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 a physical medical device, not an AI system. MRMC studies are not relevant here.

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

    Not applicable. This is a physical medical device, not an AI algorithm. Its performance is inherent to its physical characteristics and functionality.

    7. The type of ground truth used

    For the performance characteristics (cell damage, protein analysis, etc.), the "ground truth" is established through standard laboratory and engineering tests, comparing the new device's performance to the known performance of predicate devices according to established industry and regulatory standards for such devices. The "truth" is the measured physical and functional properties of the device.

    8. The sample size for the training set

    Not applicable. This is a physical medical device, not an AI/ML system that requires a training set.

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

    Not applicable. This is a physical medical device.
