    Abstract: A horn (12) connectable to an energy source (88) to amplify ultrasound displacement is connected to a transmitter (14) formed of material having relatively high mechanical Q for transmitting ultrasonic energy therethrough at a frequency f, the transmitter having a horn-shaped configuration of length that is a multiple of a half-wavelength lambda /2, and preferably this horn-shaped configuration is comprised of multiple horn segments (16a and 16b) each of a length substantially equal to a multiple of lambda /2, where lambda = c/f (c is the speed of sound in the high Q material). The transmitter has a proximal end of cross-sectional diameter D1 connected to the horn and a distal end of cross-sectional diameter D2, where D1 > D2. Ultrasonic energy transmitted through the transmitter drives a tip which is coupled to the transmitter by means of a flexible connector (20).
