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 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).
Device Story
Rapid exchange, co-axial coronary dilatation catheter; features distal balloon and radiopaque markers for positioning. Inner member accommodates guide wire; outer lumen enables balloon inflation/deflation with contrast fluid. Used by physicians in clinical settings (e.g., cath lab) to dilate stenotic coronary arteries or bypass grafts, restore flow in STEMI patients, or expand stents. Device advancement to stenosis facilitated by guide wire; balloon inflation achieves mechanical dilatation. Benefits include improved myocardial perfusion and restored coronary blood flow.
Clinical Evidence
Bench testing only. Testing included catheter preparation, bond tensile strength, body pressure integrity, kink/flexibility, and torque. Biocompatibility testing included cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, hemolysis, pyrogen, and complement activation. Results met all acceptance criteria.
Technological Characteristics
Co-axial design with tubular inner/outer members; rapid exchange. Features distal balloon and radiopaque markers. Materials include hypotube proximal shaft. Sterilization method not specified. No software or electronic components.
Indications for Use
Indicated for patients requiring balloon dilatation of coronary artery or bypass graft stenoses to improve myocardial perfusion, restoration of coronary flow in ST-segment elevation myocardial infarction, or post-implantation stent dilatation (2.0-5.0 mm models).
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.
