A device for producing electrical discharges in an aqueous medium which comprises a first electrode and a second electrode comprised of a superalloy having a cobalt content of greater than 8% by weight or optionally a nickel content of greater than 8% by weight. A high electrical voltage is applied to the electrodes to produce a voltage discharge into the medium that creates a pressure wave in the medium. The electrodes of the device exhibit high thermal shock resistance during discharge thereby reducing tip burnout.

Device for producing electrical discharges in an aqueous medium

A device for generating shock waves, specifically for medical applications, has electrodes arranged in a liquid medium, a high voltage being applied to the electrodes to generate an electrical breakdown. Particles added in powder form are suspended in the liquid medium. In order to maintain the particles in suspension, a thixotropic additive is added to the liquid medium.
