• Attributes: Therapeutic

Intended Use

The NC TREK™ OTW Coronary Dilatation Catheter is indicated for: - balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis for the purpose of improving myocardial perfusion; - balloon dilatation of a coronary artery occlusion for the purpose of restoring coronary flow in patients with ST-segment elevation myocardial infarctions; - balloon dilatation of a stent after implantation (balloon models 2.0 mm - 5.0 mm only).

Device Story

Over-the-wire (OTW) co-axial coronary dilatation catheter; features distal balloon and dual radiopaque markers for positioning. Inner lumen accommodates guidewire for navigation through stenosis; outer lumen enables balloon inflation/deflation via contrast fluid. Proximal end includes adaptation arm for inflation device connection and brachial/femoral markers for gauging position relative to guiding catheter. Used by physicians in clinical settings (e.g., cath lab) during percutaneous coronary intervention (PCI). Balloon expansion at specific pressures restores coronary flow or dilates stents. Benefits include improved myocardial perfusion and restoration of blood flow in acute myocardial infarction patients.

Clinical Evidence

Bench testing only. No clinical data presented. In vitro testing included catheter preparation, balloon inflation/deflation, shaft fatigue, shaft rupture, distal/proximal tensile strength, inner member collapse, kink/flexibility, torque, and coating integrity/particulate testing, all conducted per FDA Class II special controls guidance.

Technological Characteristics

OTW co-axial catheter design; single or dual-layer (co-extruded) balloon; radiopaque markers; brachial/femoral positioning markers. Materials evaluated per ISO 10993-1:2009. Connectivity: manual inflation device interface. Sterilization: not specified. Software: none.

Indications for Use

Indicated for patients requiring balloon dilatation of coronary artery or bypass graft stenoses to improve myocardial perfusion, patients with ST-segment elevation myocardial infarctions requiring restoration of coronary flow, and post-stent implantation dilatation (for 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.

Special Controls

*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.

The balloon segment expands to a known diameter and length at a specific inflation pressure and has two radiopaque markers under the balloon to aid in positioning the balloon in a stenosis. The co-axial shaft consists of a tubular inner and outer member. The inner lumen 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. Along the proximal portion of the shaft are brachial and femoral markers to aid in gauging the catheter's position relative to the guiding catheter tip when introducing the catheter through the guiding catheter. An adaption arm is located at the proximal end to provide access to the inflation lumen and guide wire lumen and allows connection with an inflation device.
