Claim Text:
1. An ultrasound catheter comprising: a catheter body having a proximal portion, a distal portion, a distally narrowing taper, and at least one lumen, wherein the proximal portion is stiffer than the distal portion, and the distal portion is more flexible near a distal end of the catheter body than near the proximal portion of the catheter body; an ultrasound transmission member extending longitudinally through the at least one lumen and having a proximal end, a distal end, and a distally narrowing taper; a distal head coupled with the distal end of the ultrasound transmission member and disposed adjacent the distal end of the catheter body; and at least one coupling member for coupling the ultrasound transmission member with a source of ultrasound energy, wherein the ultrasound transmission member is more flexible near its distal end than near its proximal end and contacts a guidewire, the distal portion of the catheter body and the ultrasound transmission member are sufficiently flexible to conform concomitantly with at least one bend in the guidewire extended through the at least one lumen, the distally narrowing taper of the ultrasound transmission member extends distally beyond the distally narrowing taper of the catheter body.
