Abstract:
1. A delivery system for delivering ultrasound energy, comprising: a flexible, metallic, ultrasonic wire disposed within a working channel of an endoscope, said wire extending beyond an end of the working channel for flexibly delivering ultrasound energy to an anatomic target within a human body; an insulating non-metallic layer between said flexible ultrasonic wire and an interior metallic surface of the working channel of the endoscope; and an ultrasonic energy source connected to the flexible ultrasonic wire, said energy source generating longitudinal ultrasonic energy waves and producing a first amplitude and frequency of said ultrasonic energy beyond said end of said working channel; wherein said endoscope working channel with said flexible ultrasonic wire disposed therein comprises a plurality of radii to reach the anatomic target and, at the time of formation of each radius of said plurality of radii, said energy source is configured to adjust said ultrasonic energy waves to provide ultrasonic energy at the tip of the wire to compensate for loss of said first amplitude and frequency when the tip is extended beyond an end of the working channel.
