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.
Claims27
An assembly for a catheter having a proximal end and a distal end and a longitudinal axis between the ends, the assembly designed for fracturing an occlusion within a blood vessel, the assembly comprising:
- a blunt end member connectable to the distal end of the catheter, the blunt end member sized and shaped for fitting within the blood vessel and for fracturing the occlusion, the blunt end member having a first position for allowing the blunt end member to be located at the occlusion and a second position for fracturing the occlusion;
- and
- an actuation member for moving the blunt end member between, the first, and second positions.
- whereby the blunt end member is connectable to the distal end of the catheter and the blunt end member is deliverable to the occlusion in the first position and is actuable to a second position for fracturing the occlusion.
