摘要：
Interventional catheter-based systems and methods are described herein for use in generating an initial pathway through vascular occlusions. The catheter systems generally include two elements. A first element is a Blunt Dissection Catheter including a manually actuated assembly located at the distal tip of the Blunt Dissection Catheter that performs blunt dissection in the vascular occlusion to produce a dissection track, or small pathway through the occlusion. The second element is a Sheath Catheter that serves as a conduit within which the Blunt Dissection Catheter is freely advanced, retracted and rotated. The first and second elements are used in some combination to cross vascular occlusions in both the coronary and peripheral vasculature.
