Abstract
A device for removing calculi by using an intracorporeal lithotripter comprises a single metallic probe or sonotrode which for the fragmentation of calculi is connected with an electrically controlled ultrasonic transducer for generating longitudinal oscillations which alternatively may be switched to the generation of shock or pressure waves by a pulse wave stimulated oscillation of the metallic probe or sonotrode.
