Device for the generation of shock waves utilizing a thyristor

1. A device for the generation of shock waves for the medical therapy, having an electro-hydraulic shock source, an energy storage and a switch, wherein the energy storage is a capacitor with a capacitance of between 500 nF and larger than 100 nF and the switch is a semiconductor MOSFET thyristor switch, and the electro-hydraulic shock source is a spark discharge section and the spark discharge section having two essentially pointed electrodes whose tips are arranged at a distance of 0.1 mm to 1 mm from one another, which discharges when the capacitor is charged to a voltage of between 500 V to 5000 V.
