Patent ID: 7220233

Claim:
An ultrasound catheter for disrupting occlusions in blood vessels, the ultrasound catheter comprising: an elongate flexible catheter body having a proximal end, a distal end and at least one lumen; an ultrasound transmission member extending longitudinally through the lumen of the catheter body and having a proximal end and a distal end; a distal head coupled with the distal end of the ultrasound transmission member and disposed adjacent the distal end of the catheter body; a sonic connector coupled with the proximal end of the ultrasound transmission member for coupling the ultrasound transmission member with an ultrasound transducer device; and a connector housing coupled with the proximal end of the catheter body for housing the sonic connector and a proximal portion of the ultrasound transmission member and for preventing the ultrasound transmission member from rotating relative to the catheter body; wherein the connector housing comprises a housing cavity having a shape, and the sonic connector has a shape that is complementary to the housing cavity shape, such that when the sonic connector is disposed within the housing cavity, the sonic connector shape cannot rotate relative to the housing cavity shape.
