NC Stormer OTW

Noncompliant Over-the-Wire Balloon Dilatation Catheter

NC Stormer OTW Noncompliant Over-the-Wire Balloon Dilatation Catheter

When precision and performance are paramount, the NC Stormer® OTW Noncompliant Over-the-Wire Balloon Dilatation Catheter offers controlled compliance, high pressures, comprehensive lengths, and low longitudinal growth.

How the NC Stormer OTW Works

Stent implantation often follows balloon angioplasty. Once the stent is implanted, post stent deployment as assessed by IVUS or fluoroscopy may be completed to ensure adequate stent expansion and apposition against the arterial wall.1

Nominal pressure
Rated burst pressure*

*Rated burst pressure: the maximum pressure to which a balloon is designed to be inflated (95% confidence that 99.9% will not fail below rated burst pressure). DO NOT EXCEED.
Nominal pressure: the pressure at which the balloon reaches its labeled diameter.
