The Dolphin® Pro Low Profile Crossing Support Catheter developed by Invamed, a global medical device manufacturer—is designed for precise and efficient guidewire support in complex vascular interventions. Built to navigate tight or tortuous anatomies, this low-profile catheter integrates three radiopaque markers along the distal shaft, enabling improved positional awareness and accurate lesion crossing in both peripheral arteries.
Triple Marker System
•Three strategically placed markers along the distal segment enhance fluoroscopic visibility, facilitating precise depth and orientation checks when crossing tough occlusions.
Low-Profile Construction
•Optimized for smaller vessel diameters or micro-channel crossing, reducing friction and minimizing vessel trauma.
High Pushability & Torque
•Braided or coiled shaft provides robust support while retaining flexibility, ensuring stable guidewire manipulation through heavily calcified or occluded segments.
Multi-Use Applications
•Ideal for peripheral artery disease (PAD) or complex coronary lesion crossing, offering consistent performance in subintimal or luminal track approaches.
