Claim:
An ultrasound catheter for disrupting occlusions in blood vessels, the ultrasound catheter comprising: an elongate flexible catheter body comprising a proximal end, a distal end, and a lumen, at least a portion of the catheter body having a preset bend at an angle, the bend being formed prior to insertion of the catheter body into the patient; an ultrasound transmission member extending longitudinally through the lumen of the catheter body, the ultrasound transmission member comprising a proximal end connectable to a separate ultrasound generating device, and a distal end disposed adjacent the distal end of the catheter body, at least a portion of the ultrasound transmission member being bent at an angle when the portion is disposed within the preset bend portion of the catheter body; and a distal head coupled with the distal end of the ultrasound transmission member; wherein the angle of the bend of the catheter body is greater than the angle of the bend of the ultrasound transmission member.
