Abstract

An ultrasonic percussion device uses an ultrasonic generator attached to one end of a wire by a linking assembly which includes a radially elastically deformable sleeve (7) receiving the end of the wire and provided with a conical flared section (7B); a hole (8) provided in a member (9) integral with the generator and into which the sleeve is able to be introduced, the conical section (7B) of the sleeve (7) coming into contact with a complementary conical wall (8B) provided in the hole, and a clamping element (10) able to cooperate by screwing with the member (9) and to act against the sleeve (7); the device is particularly useful for destroying atheromata in clogged arteries.
