Abstract
Abstract A device for locating and disintegrating concretions and stones in bodily cavities by means of a shock wave generator comprises a reclining surface for the patient, with an opening therein below which the generator, including a flexible precursor section, is so arranged that the fluid sealed off from the outside is in contact via the opening with the body section to be treated, either directly or indirectly via a diaphragm sealing off the precursor section. To this end, the reclining surface and the shock wave generator are displaceable with respect to each other.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
266 words
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.
Claim 2
Dependent Claim
266 words
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.
Claim 3
Dependent Claim
28 words
The apparatus of claim 1, the means for establishing movement comprising means for mounting the patient support on the table for movement between the at least two positions.
Claim 4
Dependent Claim
40 words

Claim 5
Dependent Claim
63 words
The apparatus of claim 1, the means for establishing movement comprising means for mounting the patient support on the table for movement between a first position in which the opening in the patient support is disposed substantially above the shock wave generator and a second position in which the opening in the patient support is not disposed substantially above the shock wave generator.
Claim 6
Dependent Claim
36 words
The apparatus of claim 4, further comprising means for generating an X-ray image by passing X-rays through the patient and the opening in the patient support when the patient support is disposed in the second position.
Claim 7
Dependent Claim
32 words
The apparatus of claim 1, comprising means for coupling shock waves from the shock wave generator through an elastic diaphragm to the part of the patient's body which is to be treated.
Claim 8
Dependent Claim
16 words
The apparatus of claim 1, wherein the shock wave generator is mounted on a displacing unit.
Claim 9
Dependent Claim
