Abstract

The present invention provides an apparatus and a method for using a preshaped ultrasonic probe to ablate an occlusion in a vasculature. An ultrasonic medical device comprising an ultrasonic probe having a proximal end, a distal end and a longitudinal axis therebetween and a preshaped segment along the longitudinal axis increases a surface area of the ultrasonic probe in communication with the occlusion. A method of increasing a treatment area of an ultrasonic probe to ablate an occlusion comprising inserting the ultrasonic probe with a preshaped segment into a catheter, advancing the preshaped segment beyond a distal end of the catheter and activating an ultrasonic energy source to provide an ultrasonic energy to the ultrasonic probe to ablate the occlusion. The present invention increases the surface area in communication with the occlusion, maximizes a radial span in a vasculature and expands a treatment area of the ultrasonic probe.
