摘要:
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.
