The NC TREK™ RX Coronary Dilatation Catheter is indicated for: a) balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis for the purpose of improving myocardial perforusion; b) balloon dilatation of a coronary artery occlusion for the purpose of restoring coronary flow in patients with ST-segement elevation myocardial infarction; c) balloon dilatation of a stent after implantation (balloon models 2.0 mm - 5.0 mm only).
The NC TREK RX Coronary Dilatation Catheters is a rapid exchange co-axial design with a balloon at the distal tip. The balloon segment expands to a known diameter and length at a specific inflation pressure and has radiopaque marker(s) under the balloon to aid in positioning the balloon in a stenosis. The coaxial shaft consists of a tubular inner and outer member. The inner member permits the use of a guide wire to facilitate advancement of the catheter to and through the stenosis to be dilated. The outer lumen provides for inflation and deflation of the balloon with contrast fluid. The proximal shaft consists of a hypotube with a hub on the proximal end, a tapered distal section ending distal to the guide wire notch junction, along with brachial and femoral markers.
The provided text describes a medical device, the NC TREK™ RX Coronary Dilatation Catheter, and its clearance process. However, it does not include information relevant to an AI/ML device and its associated studies (e.g., test set, training set, ground truth, expert adjudication, MRMC studies).
Therefore, I cannot extract the requested information regarding acceptance criteria and a study proving the device meets them in an AI/ML context from this document.
The document discusses in vitro bench and biocompatibility tests conducted according to specific guidance for Class II medical devices, and these tests demonstrated that the device "met all acceptance criteria and performed similarly to the predicate devices." This implies the acceptance criteria were related to the physical and biological performance characteristics of the catheter, not diagnostic accuracy or output from an AI model.
The questions you asked are highly geared towards AI/ML device evaluations. Since the provided document is for a physical medical device (coronary dilatation catheter) and not an AI/ML diagnostic or assistive tool, the requested information is not present.
§ 870.5100 Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheter.
(a)
Standard PTCA Catheter —(1)Identification. A PTCA catheter is a device that operates on the principle of hydraulic pressurization applied through an inflatable balloon attached to the distal end. A PTCA balloon catheter has a single or double lumen shaft. The catheter features a balloon of appropriate compliance for the clinical application, constructed from a polymer. The balloon is designed to uniformly expand to a specified diameter and length at a specific pressure as labeled, with well characterized rates of inflation and deflation and a defined burst pressure. The device generally features a type of radiographic marker to facilitate fluoroscopic visualization of the balloon during use. A PTCA catheter is intended for balloon dilatation of a hemodynamically significant coronary artery or bypass graft stenosis in patients evidencing coronary ischemia for the purpose of improving myocardial perfusion. A PTCA catheter may also be intended for the treatment of acute myocardial infarction; treatment of in-stent restenosis (ISR) and/or post-deployment stent expansion.(2)
Classification. Class II (special controls). The special control for this device is “Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters.” See § 870.1(e) for the availability of this guidance document.(b)
Cutting/scoring PTCA Catheter —(1)Identification. A cutting/scoring PTCA catheter is a balloon-tipped catheter with cutting/scoring elements attached, which is used in those circumstances where a high pressure balloon resistant lesion is encountered. A cutting/scoring PTCA catheter is intended for the treatment of hemodynamically significant coronary artery stenosis for the purpose of improving myocardial perfusion. A cutting/scoring PTCA catheter may also be indicated for use in complex type C lesions or for the treatment of in-stent restenosis.(2)
Classification. Class III (premarket approval). As of May 28, 1976, an approval under section 515 of the act is required before this device may be commercially distributed. See § 870.3.
