Abstract
Acoustic shock waves for medical uses are generated by an electrical discharge between two electrodes, which are mounted in a liquid medium. A catalyst is added to the liquid medium in the area of the electrodes; this catalyst partially or completely catalytically converts the gas which forms upon application of the voltage to the electrodes back into its original state or partially or completely prevents the formation of the gas.
