Abstract
Shock wave source based on the electromagnetic principle with defined focusing, with an electrically conductive, three-dimensionally curved membrane, with a coil, which is located adjacent thereto and to which current pulses can be admitted. A switchable electric connection is provided between the coil and a power supply unit. A housing is provided accommodating the membrane and the coil embedded in a coil form, between which housing and the membrane the coil form is located. A transmission medium is provided adjacent to the membrane and exerts pressure on the membrane. The coil form is made deformable and elastically compressible and is installed in the compressed state. The installed amount of the transmission medium remains unaffected during the operating state after the assembly.
