Apparatus and method for an ultrasonic medical device to treat peripheral artery disease

摘要

An apparatus and method for an ultrasonic medical device to treat peripheral artery disease. The ultrasonic medical device comprises an ultrasonic probe having a proximal end, a distal end and a longitudinal axis therebetween. The ultrasonic probe is inserted into an insertion point in a leg opposite the leg having an occlusional deposit and is moved adjacent to the occlusional deposit. An ultrasonic energy source is activated to generate a transverse ultrasonic vibration along at least a portion of the longitudinal axis of the ultrasonic probe. The transverse ultrasonic vibration creates a plurality of transverse nodes and a plurality of transverse anti-nodes along the longitudinal axis of the ultrasonic probe, generating cavitation in a medium surrounding the ultrasonic probe to ablate the occlusional deposit causing peripheral artery disease.
