Patent ID: 8133236

Claim:
An ultrasound catheter comprising: an elongate flexible catheter body having a proximal end, a distal end and a lumen extending longitudinally therethrough; an ultrasound transmission member extending longitudinally through the lumen of the catheter body, the ultrasound transmission member having a proximal end that is coupled to a separate ultrasound generating device, and a distal end that terminates at the distal end of the catheter body; a tip having a distal end and a proximal end being secured to the ultrasound transmission member, the tip being positioned at the distal end of the catheter body, and at least a portion of the tip extending beyond the distal end of the catheter body and having a width greater than a width of the catheter body; and an intermediate member positioned between and attached to the ultrasound transmission member and the catheter body to form a continuous cross-section between at least a portion of the ultrasound transmission member and at least a portion of the catheter body so as to inhibit longitudinal movement of the ultrasound transmission member relative to the catheter body, wherein the entire intermediate member is disposed on a proximal side of the proximal end of the tip.
