Apparatus for shock wave treatment
First Claim
1. An apparatus for ultrasonic shock wave treatment, comprising a shock wave transducer having a delay path comprising an acoustic coupling medium, and a membrane enclosing the delay path for placing against the body of a patient to be treated by shock waves generated by said transducer;
- an X-ray device for locating, in the patient'"'"'s body, an object to be destroyed by said shock waves, the X-ray device comprising an X-ray source having an X-ray tube, an X-ray loss-free medium being contained in the X-ray tube, the X-ray tube being arranged within the delay path and comprising means for sealing the X-ray tube against the coupling medium, the X-ray tube having a length and an axial direction, further comprising means for variably adjusting the length of the X-ray tube in the delay path in the axial direction of the X-ray tube.

Abstract
An apparatus for shock wave treatment includes a shock wave transducer with a cup-shaped body and with an X-ray location finding device for finding the location of a bodily concretion or tissue to be treated. The X-ray device includes an extensible X-ray tube with telescoping tube sections which are sealed against an acoustic coupling medium filling the delay path of the transducer by a balloon arranged within the X-ray tube. The balloon is secured to the upper section of the tube and to the lower section thereof. Overpressure or underpressure is applied to the interior of the X-ray tube to adjust its length in order to optimise X-ray location finding on the one hand, and shock wave treatment on the other hand.
