1. Apparatus for locating and disintegrating concretions within body cavities by means of shock waves, the apparatus comprising:

  • a reclining surface for a patient comprising an operating table and a patient support positioned on the table, the operating table and the patient support having an opening formed therein for location of a part of the patient'"'"'s body which is to be treated, the opening passing through both the operating table and the patient support;

    a shock wave generator comprising means for generating focussed shock waves;

    means for coupling shock waves from the shock wave generator through said opening to the part of the patient'"'"'s body which is to be treated, the means for coupling comprising at least a flexibly constructed precursor fluid section coupled with the shock wave generator, the precursor fluid section comprising at least a flexible casing extending from the shock wave generator and a body of fluid contained in the flexible casing;

    means for establishing movement of the patient support between at least two positions, one selected for disintegrating the concretion within the body part, the other selected for x-ray exposure of the patient;

    means for sealing an upper portion of the flexible casing to the periphery of the opening in the table;

    a bag containing a coupling fluid; and

    a belt for securing the bag to the patient'"'"'s body such that the bag projects through the opening in the table into contact with the fluid in the flexible casing and the bag and coupling fluid therein comprise means for coupling shock waves from the fluid in the flexible casing to the patient'"'"'s body.
