The CTO Non-Compliant PTCA Balloon Catheter (CorsairX Series) is a high-performance interventional device specifically engineered for crossing Chronic Total Occlusions (CTO) and complex coronary lesions. With its innovative HyperForm design, this catheter addresses the key challenges of CTO procedures—crossability, pushability, and precision expansion. It features a unique taper/gradual slope-tip (45°±10°) and TranSmooth™ surface technology, ensuring smooth navigation through tortuous vessels. Certified by CE and FDA, the CorsairX catheter meets global quality standards for cardiovascular interventions, making it a trusted choice for interventional cardiologists worldwide.
Optimized for CTO and complex lesion penetration
Non-compliant balloon material (PA) for stable, controlled expansion
Rapid Exchange (Rx) platform for super-fast intravascular exchange
Platinum-Iridium radiopaque markers for real-time, precise positioning
The 45°±10° taper/slope tip design enables smooth penetration of calcified or fibrotic CTO vessels, reducing procedural time and the risk of vessel injury. Its ultra-low profile (0.016 inch tip entry) ensures passage through the most challenging anatomical structures.
Equipped with thin-wall balloon technology and high-visibility Platinum-Iridium markers, the catheter offers exceptional trackability. Physicians can easily monitor its position in real time, even in tortuous coronary arteries, minimizing fluoroscopy time.
As a non-compliant balloon, it maintains a fixed diameter even under high pressure (up to 22 atm RBP), avoiding over-expansion and vessel damage. The wide size range (0.75–1.75mm diameter) supports customization for diverse lesion sizes.
The TranSmooth™ surface coating reduces friction between the catheter and vessel wall, delivering maximum pushability in torque-prone vessels. The short-track distal exit design enables rapid exchange without guidewire locking risks, enhancing procedural efficiency.

Chronic Total Occlusion (CTO) PCI: First-line device for crossing and dilating fully occluded coronary arteries.
Complex Coronary Lesions: Ideal for calcified, bifurcated, or tortuous lesions that require precise dilation.
Peripheral Vascular Interventions: Compatible with 5F/6F guiding catheters for minimally invasive procedures.
CTO-Specific Innovation: Tailored design solves unmet needs in complex PCI, with proven crossability in clinical settings.
Global Compliance: CE and FDA certifications ensure adherence to strict international regulatory standards.
Customizable Sizing: 40+ size combinations (diameter/length) meet the unique needs of each patient.
Cost-Effective Solution: Reduces procedural complications and repeat interventions, lowering long-term healthcare costs.
