The Dolphin® Zebra Crossing Catheter, presented by Invamed is a specialized crossing support catheter distinguished by its striped “zebra” pattern and high-flex design. Developed to facilitate guidewire crossing through complex or chronic total occlusion (CTO) lesions, the Zebra pattern on the shaft enhances fluoroscopic visibility, ensuring improved lesion access and precise guidewire support in challenging peripheral or coronary interventions.
Zebra Striping for Enhanced Visibility
- The catheter shaft features a distinctive striped pattern, boosting contrast under fluoroscopy and aiding real-time positional awareness in tortuous or occlusive vessels.
High Pushability & Torque
- Braided or coiled shaft architecture delivers robust torque response, critical for navigating complex plaque or calcific lesions.
Low-Friction Coating (Optional)
- Minimizes vessel resistance, promoting seamless advancement in subintimal or heavily diseased segments.
Versatile Clinical Utility
- Suitable for peripheral artery disease (PAD) and complex coronary CTO crossing, offering a stable support platform for balloon/stent delivery devices.
