Ultrasonic angioplasty device incorporating transmission member and ablation probe

摘要

The device comprises a catheter (12) with an ultrasound transmission member (20) extending through a lumen (14) of the catheter and connected at a proximal end to an ultrasound generating device (24). The member has an enlarged head (22) at the distal end and extending beyond the distal end of the catheter. The member is fixed relative to the catheter. The head (22) may include a neck portion (22b) extending within the catheter lumen (14). <IMAGE>
