摘要： An apparatus and method for an ultrasonic medical device with a variable frequency drive for ablating a biological material comprises an ultrasonic probe having a proximal end, a distal end and a longitudinal axis therebetween; a transducer that drives the ultrasonic probe over a variable frequency range, creating a transverse ultrasonic vibration along at least a portion of the longitudinal axis of the ultrasonic probe; a coupling engaging the proximal end of the ultrasonic probe to a distal end of the transducer; and an ultrasonic energy source engaged to the transducer that produces an ultrasonic energy, wherein driving the ultrasonic probe over the variable frequency range allows for the ultrasonic energy to propagate around a bend of the ultrasonic probe to ablate the biological material in communication with the ultrasonic probe.
