Abstract

A device for bypassing an occlusion in a vessel is provided. The device includes an elongated device body having a central channel which configured for accommodating a guidewire. The distal portion of the device is configured for forcing apart tissue layers of a wall of the vessel to thereby angle a portion of an inner layer into a lumen of the vessel and pulling the angled inner tissue layer against a distal end of the elongated device body thereby enabling a guide-wire advanced through the central channel and out of the distal end to puncture through the inner tissue layer and into the lumen of the vessel downstream of the occlusion.
