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
