ABSTRACT:
A method for extracorporeal shock wave lithotripsy comprises the steps of applying to a concretion to be disintegrated an acoustic shock wave and applying to the concretion to be disintegrated in sequence to said acoustic shock wave an oscillating acoustic pressure wave train having a pressure amplitude, said oscillating acoustic wave train having at least one amplitude maximum and at least one amplitude minimum.
