A therapeutical apparatus includes a measuring apparatus including a probe which generates an X-ray or ultrasonic wave in order to detect the location of a target to be treated such as calculi situated within the kidney, liver, biliary ducts. A therapeutical energy generator generates a shock wave of sufficient energy for purpose of therapy externally of the physical body and focusses it upon the target. Structure is provided for causing a displacement of the generator and the measuring apparatus around the surface of a patient. Structure is provided to activate the generator.

Extracoporeal ultrasonic lithotripter with a variable focus

A ultrasonic therapeutical apparatus comprises a plurality of ultrasonic vibrators which are disposed in a plurality of concentric circular rows and defining a ultrasonic shock wave generator. The apparatus also includes control means for independently controlling the frequency and the phase with which the ultrasonic vibrators in the respective raws are driven as well as the output levels thereof, thereby allowing only a positive pressure of the resultant ultrasonic wave to be increased while suppressing a negative pressure thereof to eliminate a cavitation effect.
