Dolphin PRO Low Profile Crossing Support Catheter

A low-profile crossing catheter with enhanced pushability and trackability, designed for tight or heavily calcified lesions in either coronary or peripheral arteries.

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.
  • Optimized for smaller vessel diameters or micro-channel crossing, reducing friction and minimizing vessel trauma.
  • Braided or coiled shaft provides robust support while retaining flexibility, ensuring stable guidewire manipulation through heavily calcified or occluded segments.
  • Ideal for peripheral artery disease (PAD) or complex coronary lesion crossing, offering consistent performance in subintimal or luminal track approaches.
