    Abstract: An example method includes generating an acoustic ultrasound wave that is focused at a focal point. The method further includes sequentially directing the focal point upon distinct portions of an object to form respective shock waves at the distinct portions of the object. The method further includes, via the respective shock waves, causing the distinct portions of the object to boil and form respective vapor cavities. The method further includes causing substantially uniform ablation of a region of the object that comprises the distinct portions. The substantially uniform ablation is caused via interaction of the respective shock waves with the respective vapor cavities. An example ablation system and an example non-transitory computer-readable medium, both related to the example method, are also disclosed.

    Abstract: An apparatus and method for using an ultrasonic medical device to treat chronic total occlusions comprises an ultrasonic probe, a transducer, a coupling engaging a proximal end of the ultrasonic probe to a distal end of the transducer and an ultrasonic energy source engaged to the transducer. The ultrasonic probe is inserted into a vasculature and placed in communication with the chronic total occlusion. The ultrasonic energy source produces an ultrasonic energy that is transmitted to the transducer, where the transducer creates a transverse ultrasonic vibration along 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, creating cavitation along a portion of the longitudinal axis of the ultrasonic probe to ablate the chronic total occlusion.
