Indications for Use
The MINI TREKTM OTW and TREKTM OTW Coronary Dilatatoin 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 ST-segment elevation myocardial infarction; c) balloon dilatation of a stent after implantation (balloon models 2.0 mm - 5.0 mm only). The MINI TREK OTW 1.20 mm Coronary Dilatation Catheter is indicated for initial balloon dilatation of the stenotic portion of a coronary artery bypass stent graft (≥ 70% stenosis).
Device Story
Over-the-wire co-axial coronary dilatation catheter with distal balloon; used for PTCA procedures. Input: guide wire for catheter advancement; contrast fluid for balloon inflation/deflation. Operation: physician advances catheter through guiding catheter to stenosis; inflates balloon to expand vessel/stent. Radiopaque markers aid positioning. Output: mechanical dilatation of stenotic coronary artery or bypass graft. Used in clinical settings (e.g., cath lab) by interventional cardiologists. Benefits: improved myocardial perfusion, restored coronary flow, and optimized stent apposition.
Clinical Evidence
Bench testing only. No clinical data provided. Testing included catheter preparation, balloon inflation/deflation, shaft fatigue, shaft rupture, tensile strength, inner member collapse, kink/flexibility, and torque. Biocompatibility testing included cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, hemolysis, pyrogen, and complement activation. All tests met acceptance criteria.
Technological Characteristics
Co-axial catheter design with distal balloon and radiopaque markers. Materials include tubular inner and outer members. Energy source: manual inflation device (contrast fluid). Connectivity: none. Sterilization: not specified. Software: none. Complies with Class II Special Controls for PTCA Catheters (September 8, 2010).
Indications for Use
Indicated for patients requiring balloon dilatation of coronary artery or bypass graft stenoses to improve myocardial perfusion, restore flow in ST-segment elevation myocardial infarction, or post-stent dilatation. 1.20 mm model indicated for initial dilatation of coronary artery bypass stent grafts with ≥ 70% stenosis.
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
