Ultrasonic angioplasty catheter device

摘要

The device comprises an ultrasound transmission member (24) in a lumen (22) of a catheter and having a distal head (26), which is rigidly mounted on the catheter. The distal head is thereby prevented from undergoing longitudinal or transverse movement separate from the catheter (20). A portion of the head is within the catheter and a further portion extends beyond the distal end of the catheter. A guide wire aperture (40) in the head permits a guidewire (42) in the lumen (22) to extend through the head.
