Abstract
The invention is directed to a catheter system having an ultrasonic delivery device, a dilatation balloon, and a stent. The ultrasonic distal head is used to ablate a lesion permitting the dilation balloon to cross the lesion for dilatation and for delivering the stent to the lesion. A catheter body includes a first lumen for dilatation balloon expansion control fluid, and a second lumen for the guide wire. The ultrasonic distal head includes a guide wire aperture large enough to permit complete retraction of the guide wire so that the guide wire may be replaced with another while the catheter remains in place within the vasculature of the patient.
