Abstract
The present invention provides an apparatus and a method for an ultrasonic medical device with a non-compliant balloon used to ablate a biological material. The ultrasonic medical device comprises an ultrasonic probe, a catheter surrounding the ultrasonic probe, a balloon supported by the catheter and an inflation lumen located along a longitudinal axis of the catheter. The ultrasonic probe is inserted into a vasculature and the catheter comprising the balloon is advanced until the balloon is adjacent to the biological material. The balloon is inflated until at least a portion of an outer surface of the balloon engages the biological material. The ultrasonic probe is energized to produce a transverse ultrasonic vibration that vibrates at least a portion of the balloon to ablate the biological material into a particulate.
