1. A method of fracturing a frame of a deployed prosthesis, the method comprising:
advancing a system to a site of the deployed prosthesis, wherein the system includes a shaft, a tip assembly, an ultrasonic electric generator, and an ultrasonic transducer;
positioning the tip assembly of the system in apposition with a portion of the frame of the deployed prosthesis;
placing a cutting edge of the tip assembly in contact with the portion of the frame;
applying a first longitudinal force to the shaft such that the cutting edge maintains contact with the portion of the frame; and
activating the ultrasonic generator and the ultrasonic transducer to vibrate the tip assembly to fracture the portion of the frame.
