Patent ID: 8790291

Claim:
An ultrasound catheter system for disrupting occlusions in blood vessels, the system comprising: an ultrasound catheter device, 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 guidewire tube having a proximal end, a distal end, at least one lumen, and at least one aperture, the at least one aperture being disposed between the proximal end and the distal end of the guidewire tube and within 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; a proximal housing coupled with the proximal end of the catheter body and housing the sonic connector and a proximal portion of the ultrasound transmission member, wherein the housing includes at least one fluid inlet for allowing passage of one or more heat dissipating fluids into an inner cavity of the housing, and wherein the lumen of the catheter body is in fluid communication with the lumen of the guidewire tube such that at least a portion of the heat dissipating fluid(s) introduced into the cavity passes through and out of the distal end of the guidewire lumen; an ultrasound generator removably coupled with the ultrasound catheter device; and a fluid cooling device removably coupled with the ultrasound catheter device for cooling the heat dissipating fluid(s).
