Abstract

Described is a device for producing focussed sound waves for therapeutic applications and particularly for breaking up concretions. The device has a sound-generation unit with at least one sound-radiating surface which radiates sound waves which are focussed by a focussing unit. The invention is characterized in that at least the focussing unit is divided into segments which can be moved relative to each other.
