The PTCA Non-Compliant (NC) Balloon Catheter is a high-pressure angioplasty device designed for precise lesion dilation, post-stent expansion, and optimization during percutaneous coronary interventions (PCI). Constructed with a non-compliant balloon material, it maintains its nominal diameter even at high inflation pressures, ensuring accurate vessel sizing and controlled expansion. Its low-profile design, excellent trackability, superior pushability, and reliable crossability enable effective performance in complex coronary lesions while providing compatibility with standard guide wires and guiding catheters.
