Abstract
A system for fracturing a frame of a deployed prosthesis with ultrasonic vibration includes a shaft, a tip assembly, an ultrasonic electric generator, and an ultrasonic transducer. The shaft includes a proximal portion and a distal portion. The tip assembly is coupled to the distal portion of the shaft. The tip assembly includes a cutting edge. The ultrasonic transducer is electrically coupled to the ultrasonic generator. Ultrasonic vibration generated by the ultrasonic transducer is translated to the tip assembly. The cutting edge of the tip assembly is configured to focus the vibration of the tip assembly onto a frame of a deployed prosthesis to fracture the frame of the prosthesis. The ultrasonic transducer may be coupled to the proximal portion or the distal portion of the shaft.
