Abstract
An electrode construction is provided for electrohydraulic shock wave generation such as for extracorporeal kidney stone destruction. The construction includes a reflector adapted to be filled with liquid such as water for coupling to a human body. The reflector has a focus point. An insulated base supports a plurality of pairs of electrodes, and is movable relative to the reflector. The insulating base is moved to bring successive pairs of electrodes into substantial coincidence with the focus point of the reflector. Upon such movement electrical connection is automatically made to extensions of the pair of electrodes having their spark gap substantially coincident with said focus point.
