Intended Use

The NC Emerge PTCA Dilatation Catheters are intended to enable dilation of stenotic small and large lumen coronary vessels.

Device Story

NC Emerge PTCA Dilatation Catheter is a sterile, single-use intravascular device; consists of a shaft with a distal inflatable balloon and two radiopaque marker bands. Used in interventional cardiology procedures to dilate stenotic coronary arteries or bypass grafts; also used for post-stent expansion. Operated by physicians in a clinical setting. The device is positioned via fluoroscopic guidance using marker bands; balloon is inflated to a specific diameter and pressure to restore vessel patency or ensure stent apposition. Benefits include improved myocardial perfusion and optimized stent deployment. Available in Monorail and Over-the-Wire platforms with various diameters and lengths.

Clinical Evidence

Bench testing only. Testing included biocompatibility (cytotoxicity, sensitization, reactivity, toxicity, pyrogenicity, hemocompatibility) and in-vitro performance (crossing profile, burst pressure, fatigue, compliance, inflation/deflation time, bond strength, torque, radiopacity, coating integrity, and stent compatibility).

Technological Characteristics

Intravascular balloon catheter; Monorail and Over-the-Wire configurations. Features radiopaque marker bands for positioning. Includes balloon/catheter coatings for insertion/withdrawal. Diameters 2.0-6.0mm; lengths 6-30mm. Sterilized, single-use. Complies with FDA Class II Special Controls for PTCA Catheters (Sept 2010).

Indications for Use

Indicated for balloon catheter dilatation of stenotic native coronary arteries or bypass grafts to improve myocardial perfusion in patients with atherosclerosis. Balloon models 2.00-5.00 mm are also indicated for post-delivery expansion of bare metal and drug-eluting stents.

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.

## Device Description

The NC Emerge PTCA Dilatation Catheters are sterile, single-use, intravascular medical devices. The catheter consists of a shaft with a balloon near the distal tip. The balloon is designed to provide an inflatable segment of known diameter and length at recommended pressures. The NC Emerge PTCA Dilatation Catheter is offered in both Monorail (MR) and Over-The-Wire (OTW) platforms. There are two (2) radiopaque marker bands located under the balloon to aid in positioning the system during the procedure. Coatings are applied to the balloon and catheter to enhance insertion and withdrawal performance.

The NC Emerge PTCA Dilatation Catheter will be available in select combinations of 2.0-6.0mm diameters and 6-30mm lengths as shown below:
