Abstract
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, in some embodiments, a guidewire tube extending through the lumen. A distal head for disrupting occlusions is coupled with the distal end of the ultrasound transmission member and is positioned adjacent the distal end of the catheter body. Some embodiments include improved features such as a bend in the catheter body for enhancing positioning and/or advancement of the catheter.
