The True™ BAV Balloon Valvuloplasty Catheter is indicated for balloon aortic valvuloplasty.

The True™ BAV Balloon Valvuloplasty Catheter is a high performance balloon catheter consisting of an over-the-wire catheter with a balloon fixed at the distal tip. The proprietary, non-compliant, low profile balloon is designed to provide consistent balloon diameters and lengths. Two radiopaque markers delineate the working length of the balloon and aid in balloon placement. The coaxial catheter includes an atraumatic tip to facilitate advancement of the catheter to and through the valve. The over-the-wire catheter is compatible with .035" quidewire and is available in 100 cm working length. The proximal portion of the catheter includes a female luer-lock hub connected to the inflation lumen, and a female luer-lock hub connected to the guidewire lumen. Packaged with every product is a profile reducing sheath that is positioned over the balloon for protection before use. A re-wrapping tool is also provided on the catheter shaft. This product is not manufactured with any latex.

The provided text describes a medical device, the True™ BAV Balloon Valvuloplasty Catheter, and its substantial equivalence to predicate devices, rather than a study evaluating an AI/ML device. Therefore, much of the requested information regarding acceptance criteria and studies for AI/ML performance (e.g., sample sizes for test and training sets, expert qualifications, MRMC studies, standalone performance) is not applicable here.

However, I can extract the information related to device performance and acceptance criteria as presented in the document for this specific medical device.

1. Table of Acceptance Criteria and Reported Device Performance

The document states that the "True™ BAV Balloon Valvuloplasty Catheter met all predetermined acceptance criteria of design verification and validation as specified by applicable standards, guidance, test protocols and/or customer inputs."

However, specific numerical acceptance criteria and their corresponding reported device performance values are not provided in the text. The document lists the types of in-vitro tests performed, implying that for each of these, acceptance criteria existed and were met.

Here's a table based on the provided text, outlining the tests performed, which inherently means they had acceptance criteria that were met, but the specific numerical criteria and results are not detailed.

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

This information is not provided in the document. The text describes in-vitro (bench) testing, not clinical studies with patients or data sets in the typical sense for AI/ML validation. There's no mention of sample sizes for individual tests or the provenance of any "data."

3. Number of Experts Used to Establish Ground Truth and Qualifications

This information is not applicable to this type of device submission. There is no mention of experts or ground truth establishment as it typically refers to for AI/ML diagnostic devices. The acceptance criteria for this device are based on engineering specifications and performance standards through in-vitro testing.

4. Adjudication Method

This information is not applicable. Adjudication methods (like 2+1 or 3+1) are relevant for reconciling differing expert opinions, which isn't part of this device's testing and validation process.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for evaluating the impact of AI on human reader performance, which is not applicable to a physical medical device like a balloon catheter.

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

No, a standalone algorithm-only performance study was not done. This device is a physical catheter, not an AI algorithm.

7. The Type of Ground Truth Used

The "ground truth" for this device's validation is based on engineering specifications, established performance standards, and internal risk assessment procedures as demonstrated through the in-vitro tests listed. It's not based on expert consensus, pathology, or outcomes data in the way an AI/ML diagnostic device's ground truth would be.

8. The Sample Size for the Training Set

This information is not applicable. The concept of a "training set" applies to machine learning algorithms, which is not what this device is.

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

This information is not applicable as there is no "training set" for this device.
