Dolphin Sub-Intimal Entry Catheter
A sub-intimal entry system aiding re-entry into the true lumen after sub-intimal crossing in CTO or heavily occluded segments, ensuring minimal dissection expansions.
The Dolphin Sub-Intimal Entry Catheter, by Invamed—a global medical device manufacturer—is uniquely designed to assist in subintimal dissection and re-entry in chronic total occlusions (CTOs) or heavily diseased vascular segments. By providing a targeted pathway to the subintimal space and then guiding re-entry into the true lumen, Dolphin enhances procedural success in complex peripheral or coronary interventions.
Dedicated Subintimal Navigation
Engineered tip or “needle” design helps negotiate the subintimal plane, enabling operators to bypass occlusive lesions.
True Lumen Re-Entry
Specialized distal tip geometry assists in precision re-entry to the true lumen, improving success rates in otherwise intractable CTOs.
High Pushability & Torque
Braided or coiled shaft construction delivers robust force transmission for crossing tough plaque or calcifications.
Hydrophilic Coating (optional)
Minimizes friction against vessel walls, reducing dissection risk and procedural time in challenging anatomies.
Wide Clinical Utility
Indicated for peripheral artery disease (PAD) with occlusive lesions, especially superficial femoral or popliteal arteries. May also be adapted for select coronary interventions.
Kontraindikasi
Extremely tortuous vessels, advanced dissection risk, or patient conditions that preclude subintimal techniques.
