Abstract
A medical instrument for treating biological tissue comprises a housing (2), a pressure wave generation means (4) and a transmission means (8) for coupling the unfocused pressure waves into the body of living beings. The transmission means (8) comprises a pressure chamber (12) having an inlet and an outlet end, the pressure chamber (12) containing a liquid (14) into which pressure waves from the pressure wave generation means (4) can be coupled, which pressure waves can be transmitted to a membrane (16) arranged at the outlet end of the pressure chamber (12) which membrane (16) couples the pressure waves transmitted from the liquid unfocusedly into the biological tissue.
