Abstract
In extracorporal lithotripsy a shock wave that is focussed on a concrement is followed by a pain producing pressure wave. This wave is filtered by means of a membrane bulging inwardly into the focussing chamber, closing the same and having a thickness smaller than the predominant wave length of the shock wave.
