Abstract
Disclosed is a medical instrument for treating biological tissue, comprising a device generating extracorporeal pressure waves and a transmission element (2) coupling said pressure waves into the body of living beings. The pressure wave is generated by a stroking member (10) impacting on a transmission element (2) and is transmitted inside the transmission element. Said transmission element comprises a boundary surface at the outlet thereof, which is curved towards the inside and is configured such that the pressure waves can be coupled into the biological tissue and can be focused therein.

11. A medical instrument for the treatment of biological tissue by generating extracorporeal pressure waves and adapted to couple the pressure waves into the body of living beings, comprising:
-
an impact member (10) for hitting against an entry boundary face (20) of a transmission element (2) thereby generating extracorporeal pressure waves which are propagated in and travel through the transmission element (2) from the entry boundary face (20) thereof to an opposite remote inwardly curved exit boundary surface (19) configured such that the transmission element (2) is adapted to be placed in contact with the biological tissue, and the pressure waves are adapted to then be coupled into and focused relative to the biological tissue, and impedance-adjusting means (5) provided contiguous the inwardly curved opening exit boundary surface (19) of the transmission element (2), adapted for improving the coupling of the pressure wave into the biological tissue, wherein the exit boundary surface (19) of the transmission element (2) travels a stroke less than 0.5 mm due to the impact member (10) hitting the entry boundary face (20) of the transmission element (2), and wherein the transmission element (2) is in the shape of an exponential born, and the transmission element (2) has a larger diameter at the exit boundary surface (19) than at the entry boundary face (20). - View Dependent Claims (12)
