Abstract
An acoustic wave generator has a shockwave source contained in a housing with a volume between the shockwave source and the location at which the acoustic waves exit the generator which is divided into two sub-volumes, each filled with acoustic propagation medium. The location at which the acoustic waves exit the generator is in the form of a deformable cushion which permits the generator to conform to the surface of a subject to be irradiated with the acoustic waves. The liquid propagation medium in both sub-volumes is circulatable, with the amount of liquid propagation medium in the sub-volume forming the cushion being variable.
