First Claim
1. In an apparatus for a non-contacting disintegration of concretion situated in a body of a life form, said apparatus including a shock wave generator having energy waves being focused at a focal point on an isocenter positioned in a target region of the body, said generator having coupling means for transferring the energy from the generator to the body, said coupling means including a container having at least one flexible wall and being filled with a coupling agent, the improvements comprising a patient bed having a surface extending in a longitudinal direction for receiving a body, said bed having an aperture through said surface in an area below said isocenter, a carriage supporting the shock wave generator for pivotal movement around a longitudinal axis spaced above the surface of the bed and extending parallel to the longitudinal direction with the shock wave generator being below the bed with the coupling means located between the generator and bed and the focal point being on said longitudinal axis, said carriage being moveable along the longitudinal direction from a working position with the coupling means extending through the aperture and the flexible wall contacting said body to a removed position with the focal point being moved along the longitudinal axis, an X-ray unit with an X-ray emitter and radiator receiver, and means for separately adjusting the position of the X-ray unit while the shock wave generator is in the working position comprising a C-shaped carrier mounting the receiver and emitter on opposite sides of the bed at the working position and having a pivot point lying on said longitudinal axis so that while the shock wave generator is treating a patient, the X-ray unit can be adjusted and operated without imaging the generator on an X-ray image.

Abstract
The apparatus for non-contacting disintegration of concretions situated in a life form includes a patient bed, a shock wave generator secured on a carriage below the surface of the bed with an arrangement for coupling energy from the shock wave generator positioned between the generator and the bed; an X-ray unit being mounted for pivotable movement on a longitudinal axis and used for positioning the patient with the isocenter of the region to be treated to lie on the longitudinal axis at a space above the surface of the bed and the carriage for the shock wave generator moving the focal point of the shock wave generator along said longitudinal axis from a working position with the energy focused on the isocenter to a remote position. The arrangement for mounting the X-ray unit includes a C-shaped carrier, which will pivot around the longitudinal axis and positions the X-ray radiator or emitter on an opposite side from the radiation receiver. In addition, the apparatus will pivot the shock wave generator around the same longitudinal axis and the C-shaped carrier is preferably pivotable around a second axis perpendicular to the longitudinal axis.
