Abstract
Disclosed is an apparatus for the treatment of biological tissue as well as for destroying concretions by means of focussed acoustic waves, having a sound generating unit which a control unit triggers in such a manner that the unit generates acoustic waves of a specific frequency and energy, and a focussing unit which focusses the generated waves in a focal area. The present invention is distinguished by the sound generating unit (2) being provided, in an as such known manner, with a plane or only slightly curved radiation area in such a manner that the generated wave is an essentially plane wave and that the focussing unit (5) disposed in a fixed spatial relationship to the sound generating unit being provided with a Fresnel lenslike structure on the sound entry and/or sound exit area.
