Boston Scientific NC EMERGE PTCA Dilatation Catheter

Boston Scientific NC EMERGE™ PTCA Dilatation Catheter
The Boston Scientific NC EMERGE™ PTCA Dilatation Catheter is a noncompliant coronary balloon catheter designed to deliver precise balloon expansion, excellent deliverability, and dependable post-dilatation performance during PCI procedures. Boston Scientific describes NC EMERGE as its “most advanced PTCA catheter,” highlighting an ultra-low lesion entry profile, over-the-inner tip design, and reduced shaft profile to support performance in tortuous anatomy.

Engineered for interventional cardiology, the NC EMERGE is intended for balloon dilation of the stenotic portion of a coronary artery or bypass graft stenosis to improve myocardial perfusion. The official instructions for use also state that balloon models 2.00 mm to 5.00 mm are indicated for the post-delivery expansion of balloon-expandable stents, making the catheter suitable for both lesion preparation and post-stent optimization.

The catheter’s design focuses on control and lesion access in challenging coronary anatomy. Boston Scientific highlights a 0.017-inch lesion entry profile, while its performance materials emphasize improved flexibility, better mid-balloon profile, and lower balloon growth compared with certain comparator noncompliant balloons. These features support more controlled dilatation where precise sizing and stent apposition are important.

According to the IFU, the NC Emerge MR PTCA Dilatation Catheter is a noncompliant rapid-exchange catheter with a low-compliance balloon near the distal tip. The inner lumen permits the use of guidewires up to 0.014 in (0.36 mm), helping physicians advance the catheter to and through the lesion or stent being treated. FDA records also identify both Monorail and Over-the-Wire versions of the NC EMERGE platform.

Built for routine and complex coronary interventions, the Boston Scientific NC EMERGE balloon catheter is designed to support accurate vessel dilatation, post-dilatation after stent placement, and reliable deliverability in difficult lesions. Its noncompliant balloon platform makes it a strong option for physicians seeking controlled expansion and dependable coronary performance during PCI.
