  • Device for generating shock waves for non contact disintegration of calculi
    Patent number: 5458652
    Abstract: The invention relates to a device for generating shock waves by means of a park gap by using two electrodes. At a spark gap, apart from the desired shock waves, low frequency sound parts are generated. These sound parts have a disturbing effect during therapy. According to the invention, for the reduction of the low frequency sound parts it is provided to arrange the electrodes in a pressure-tight tube surrounding them.
