The Filao NC RX PTCA Dilatation Catheter is a standard Rapid Exchange (RX) PTCA catheter with a non-compliant inflatable balloon at the distal part and an atraumatic, tapered tip to aid in crossing the tight stenosis. Two radiopaque markers facilitate proper balloon positioning across the stenosis, and a hydrophilic coating improves pushability of the catheter.

The Filao NC PTCA RX Catheter is available in balloon diameters ranging from 2.00 mm to 4.50 mm, and balloon lengths ranging from 8mm to 30 mm in step of 1 mm. The maximum recommended guide wire diameter is 0.014"

AI/ML Overview

This document is a 510(k) summary for the Filao NC RX PTCA Dilatation Catheter (K141933). It describes the device, its intended use, and a comparison to predicate devices, along with performance data.

Here's an analysis of the provided text in relation to your questions:

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

The document does not explicitly provide a table of acceptance criteria with corresponding performance results. Instead, it lists various non-clinical tests conducted, implying that the device met internal acceptance criteria for each test to demonstrate substantial equivalence. The performance data is summarized in a qualitative manner.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document mentions "non-clinical testing" but does not specify the sample sizes for these tests. It also does not provide information on the country of origin of the data or whether the tests were retrospective or prospective. Given it's non-clinical testing, it would typically be laboratory-based rather than patient data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not applicable and therefore not provided. The study detailed is non-clinical performance testing of a medical device (dilatation catheter), not a diagnostic study requiring expert ground truth for interpretation of medical images or patient conditions.

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

This information is not applicable and therefore not provided. The study involves non-clinical performance testing of a physical device, not a diagnostic study with human observers requiring 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

No, an MRMC comparative effectiveness study was not done. This document is for a physical medical device (catheter), not an AI/software device that would involve human readers or AI assistance.

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

This concept is not applicable here. The device is a physical catheter, not an algorithm.

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

For a physical medical device like a PTCA catheter, "ground truth" for performance testing typically refers to:

Engineering standards and specifications: The device's performance is compared against pre-defined engineering requirements and industry standards (e.g., ISO standards for medical devices).
Reference measurements: Using calibrated equipment to measure physical properties like dimensions, burst pressure, inflation/deflation times, bond strengths, etc., and comparing these measurements to the specified design parameters.
Predicate device comparison: Performance data is also often compared to that of a legally marketed predicate device to demonstrate substantial equivalence.

The document implicitly states that the non-clinical testing addressed various considerations to demonstrate substantial equivalence, meaning the device met its design specifications and performed comparably to predicate devices.

8. The sample size for the training set

This information is not applicable and therefore not provided. This is not an AI/machine learning study, so there is no "training set."

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

This information is not applicable and therefore not provided. This is not an AI/machine learning study.
