The NC TREK NEO™ Coronary Dilatation Catheters are indicated for:
a) Balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis, for the purpose of improving myocardial perfusion
b) Balloon dilatation of a coronary artery occlusion, for the purpose of restoring coronary flow in patients with STsegment elevation myocardial infarction
c) Balloon dilatation of a stent after implantation (balloon models 2.00 mm - 5.00 mm only)

NC TREK NEO is a Non-Compliant (NC), Rapid Exchange (RX), Coronary Dilatation Catheter (CDC). The catheter is a rapid exchange co-axial design with a balloon at the distal tip. The proximal lumen provides for inflation of the balloon with contrast medium. The central distal lumen permits the guide wire to facilitate advancement of the catheter to and through the stenosis to be dilated. The outside diameter (OD) of the distal end of the device, including the distal shaft, tip, and the balloon are coated with Hydrophilic Coating.
Radiopaque markers are positioned on the inner member underneath the balloon to provide accurate positioning of the balloon in the artery. The balloon is designed to provide an expandable segment of known diameter and length at specified pressures. Proximal shaft markers located on the outer shaft aid in gauging the dilatation catheter position relative to the guiding catheter tip when introducing the catheter through the guiding catheter. The Single arm on proximal end of the device provides access to the inflation lumen. It is designed with a Luer-lock fitting to facilitate connection to an inflation device.
The NC TREK NEO™ Coronary Dilatation Catheter will be available in select combinations of 1.50-6.00mm diameters and 6-25mm lengths.

This document concerns the 510(k) premarket notification for the NC TREK NEO™ Coronary Dilatation Catheter (K220634). The information provided does not contain details about acceptance criteria, device performance, and study design typically found in reports for AI/ML-driven medical devices. Instead, it describes a conventional medical device (a PTCA catheter) and establishes substantial equivalence to a predicate device through a comparison of design, materials, manufacturing, sterilization, and non-clinical performance data.

Therefore, many of the requested fields cannot be filled as they are explicitly related to studies and acceptance criteria for AI/ML devices, which are not applicable here.

Here's a breakdown of the available information and what cannot be provided:

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

The document lists various performance tests conducted on the device. However, it does not provide a table with specific quantitative acceptance criteria or the reported device performance values for these tests. It only states that the tests supported a determination of substantial equivalence and raised no new safety or performance issues.

2. Sample size used for the test set and the data provenance:
Not applicable. This is a conventional medical device, not an AI/ML device relying on a test set of data. The "test set" here refers to the physical devices manufactured for bench and biocompatibility testing. The exact number of devices or components used for each test is not specified in this summary, nor is data provenance in the context of clinical data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
Not applicable. Ground truth and expert consensus are concepts for AI/ML device validation, which is not relevant for this conventional catheter.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable for this type of device and study.

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 device is not an AI-assisted device.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This device does not involve an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
Not applicable. The "truth" for this device's performance is determined by established engineering standards, material properties, and biological compatibility testing, not by expert consensus on clinical data or pathology in the context of an AI/ML algorithm.

8. The sample size for the training set:
Not applicable. This device does not involve a training set for an AI/ML algorithm.

9. How the ground truth for the training set was established:
Not applicable. This device does not involve a training set for an AI/ML algorithm.
