Indications for Use
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 perfusion; b) balloon dilatation of a coronary artery occlusion for the purpose of restoring coronary flow in patients with ST-segment elevation myocardial infarction; c) balloon dilatation of a stent after implantation (balloon models 2.0 mm - 5.0 mm only).
Device Story
NC TREK RX Coronary Dilatation Catheter is a rapid exchange, co-axial balloon catheter used by physicians in clinical settings for percutaneous transluminal coronary angioplasty (PTCA). The device features a distal balloon and radiopaque markers to assist in positioning within a stenosis. The inner member accommodates a guide wire for navigation; the outer lumen allows for contrast fluid inflation/deflation to expand the balloon to a specific diameter and length. By dilating stenotic lesions or stents, the device improves myocardial perfusion or restores coronary flow. The catheter includes a proximal hypotube, hub, and markers for orientation. It is a line extension of an existing predicate, offering additional balloon size configurations.
Clinical Evidence
Bench testing only. Testing included balloon crossing profile, inflation/deflation, fatigue (including within a stent), rupture, compliance, kink/flexibility, torque, and coating integrity. Biocompatibility testing included cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, hemolysis, pyrogen, and complement activation. All tests met acceptance criteria.
Technological Characteristics
Rapid exchange co-axial catheter; balloon diameters 1.50-5.00 mm; single-layer or co-extruded balloon design; radiopaque markers; hypotube proximal shaft; contrast-fluid inflation; non-powered mechanical device.
Indications for Use
Indicated for patients requiring balloon dilatation of stenotic coronary arteries, bypass grafts, or coronary artery occlusions (including STEMI patients) to improve perfusion or restore flow, and for post-stent dilatation.
Regulatory Classification
Identification
Standard PTCA Catheter: 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. Cutting/scoring PTCA Catheter: 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.
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.
