1. An improved therapeutic ultrasound delivery system comprising:

  • a) an ultrasound signal generator for providing an ultrasound drive signal;

    b) an ultrasound transducer receiving the ultrasound drive signal for converting the ultrasound drive signal into ultrasound vibration;

    c) an ultrasound catheter, having proximal and distal ends, attached at the proximal end to the ultrasound transducer, for transmitting ultrasound vibration from the ultrasound transducer to effect treatment at a desired anatomical site; and

    d) a device for measuring ultrasonic activity at the distal end of the catheter to verify proper operation of the ultrasound generator, the ultrasound transducer, and the catheter.
