摘要： Ultrasound catheter devices and methods of the present invention generally provide for ablation and/or disruption of vascular occlusions. An ultrasound transmission member, such as a wire, transmits vibrational energy from an ultrasound transducer to a distal head of the catheter to disrupt vascular occlusions. At least one absorber member is disposed on or around the ultrasound transmission wire at a location adjacent the sonic connector of the catheter. The absorber member absorbs heat, vibrations, and/or the like from the ultrasound transmission wire at or near the area where the transmission wire is coupled with the sonic connector. The absorptive function typically slows the process of wear and tear on the transmission wire, thus extending the useful life of the ultrasound catheter.

摘要： Ultrasound catheter devices and methods provide enhanced disruption of blood vessel obstructions. Generally, ultrasound catheters include 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. Improved features of ultrasound catheters include prevention of independent rotation of the ultrasound transmission member, a safety anchor for the distal head, a one-piece transmission member/distal head and the like.
