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.
Claims18
A method for treating an occlusion in an artery comprising:

- positioning a device around the treatment area;
- and
- delivering a medicament in mixture with a dye.
A method for treating an occlusion in an artery comprising:
- applying endovascular ultrasound energy to a treatment area to enhance the vessel permeability;
- positioning a device within the treatment area;
- and
- delivering a medicament in mixture with a dye.
A method for treating chronic total occlusion in an artery comprising:
- performing an endovascular ultrasound procedure at a treatment area;
- and
- delivering a medicament to the treatment area.
A method for treating an occlusion in an artery comprising:
- performing an ultrasound angioplasty at a treatment area;
