Improved ultrasound catheter devices

摘要

The present application relates to ultrasound catheter system (20) for disrupting occlusions in blood vessels, the ultrasound catheter system comprising: an elongate flexible catheter body (22) having a proximal end, a distal end and at least one lumen; an ultrasound transmission member (24) extending longitudinally through the lumen of the catheter body and having a proximal end and a distal end; a distal head (26) coupled with the distal end of the ultrasound transmission member and disposed adjacent the distal end of the catheter body; a sonic connector (52) coupled with the proximal end of the ultrasound transmission member; a connector housing (4) having a proximal end and a distal end, the distal end coupled with the proximal end of the catheter body, for housing the sonic connector and a proximal portion of the ultrasound transmission wire and for preventing the ultrasound transmission member from rotating relative to the catheter body; and an ultrasound transducer device (400) removably couplable with the sonic connector and the proximal end of the connector housing.
