Abstract: A method of operating an ultrasound catheter includes providing an elongate catheter body having at least a first lumen; providing a housing coupled with a proximal end of the elongate catheter body, the housing having an inner cavity; providing a fluid inlet in fluid communication with at least one of the first lumen and the inner cavity; providing a sonic connector coupled to a proximal portion of an ultrasound transmission member; providing vibration absorption O-rings disposed in the inner cavity around at least a portion of the ultrasound transmission member, the plurality of vibration absorption O-rings being located distal to the sonic connector; and delivering fluid to the fluid inlet to supply the fluid at least distally into the first lumen of the elongate catheter body to dissipate heat received from the ultrasound transmission member in the first lumen of the elongate catheter body.

Abstract: Ultrasound catheter devices and methods provide enhanced disruption of blood vessel obstructions. Generally, an ultrasound catheter device includes an elongate flexible catheter body with one or more lumens, an ultrasound transmission member extending longitudinally through the catheter body lumen and a distal head coupled with the transmission member and positioned adjacent the distal end of the catheter body for disrupting occlusions. A proximal housing of the catheter device may include one or more features for dissipating heat from the ultrasound transmission wire, such as a fluid inlet aperture for passage of fluid, use of heat conductive materials in the proximal housing, surface features to increase the housing's surface area, heat conductive members disposed adjacent the transmission member and the like. Various irrigation fluids may be used, such as cooled, oxygen supersaturated or lubricious fluids.
