Shock wave generator for an installation for non-contacting disintegration of calculi in the body of a life form

A shock wave generator for an installation for non-contacting disintegration of calculi in the body of a life form has a coil with spirally arranged turns and a membrane formed of an electrically conductive material lying opposite said coil and terminating a space filled with a fluid, the coil being connectable to a high-voltage supply. To assure a high useful life of the membrane without a significant reduction in the efficiency of conversion of electrical energy into shock energy, a distance increased in comparison to regions of low voltage difference is present between the coil and the membrane in regions of high voltage difference between windings of the coil and the membrane.
