A new pressure wave generator for extracorporeal lithotripsy.
A new pressure wave generator has been designed for the Storz Modulith extracorporeal lithotripter. It consists of an electromagnetic cylindrical pressure wave source and a focusing parabolic reflector. Focus size has been designed using electro-acoustic puls forming network (EA-PFN) techniques. Schlieren photographs of the pressure wave are shown. Pressure in the focus is given as a function of PFN charging voltage.
