ABSTRACT:
Disclosed herein is a blunt end assembly including a catheter and a blunt end member. The blunt end member includes jaw sections which have a first closed position for locating the blunt end member at the site of the occlusion within the native lumen of the blood vessel and a second open position wherein the jaw sections are able to press against the interior walls of the lumen adjacent the occlusion. The assembly includes an actuation member for moving the jaw sections from the closed to the open positions repeatedly resulting in a fracturing of the occlusion. A guide wire may be thread through an internal opening in the catheter and the blunt end member and after fracturing, across the occlusion.
