Abstract
A lithotripter having a shockwave generator having a cavity filled with water, further having an ultrasonic, locating transducer mounted by means of a holding device which includes metallic inner and outer shells each having a large acoustic impedance as compared with water and an acoustically attenuating layer interposed between the two shells; the shells are spaced from each other so that the shockwaves will be eliminated by interference.
