Abstract: The invention relates to an apparatus and a process for optimized electro-hydraulic pressure pulse generation that records characteristic parameters which can be measured insusceptible to error and compared with set values. The object of the invention is achieved by an apparatus in which an electro-hydraulic shock wave system is provided with a measuring and control device (13a, 13b) that measures the discharge current between the electrode tips (4, 5), and a process that influences the system parameters by means of the apparatus.

Abstract: The invention relates to an apparatus for the generation of shockwaves, consisting of a pressure pulse source (7), at least one reflector element (2, 3, 102, 103, 104), a shockwave permeable diaphragm (8) and a shockwave conducting medium and enables the generation of different shockwave profiles in the treatment area without extensive modification or remounting. For this purpose the apparatus is equipped with an adjustment mechanism for changing the size of the reflection surface (5) located within the radiation path of the primary pressure pulse.
