    Abstract: Apparatus for dissolving concretions within a bodily cavity, for example in the gall bladder, under the action of a solvent fluid applied within the bodily cavity, comprises an ultrasonic transducer arranged to be coupled to the exterior of the patient's body and to be focussed on selected parts of the bodily cavity. The transducer emits ultrasonic waves within a frequency range of between 20 and 40 kHz and with just enough power to generate cavitations in bodily cavity fluid within the body cavity, or in the solvent fluid, or in both of these fluids to cause dispersion therebetween.

    Abstract: There is disclosed, a piezoelectric transducer for generating focussed ultrasonic shock waves for use in lithotripsy. The ultrasonic shock waves are emitted in pulsed form and can be transmitted by way of a coupling medium to the body of a patient to be treated. The transducer comprises a substantial member of individual piezoelectric transducer elements of ceramic or like material which are connected to the poles of a pulse generator and are fixed to a support in mosaic form and with their sides electrically insulated from one another. The acoustic termination of the transducer elements is essentially free from reflection. An intermediate medium of at least one layer, the acoustic impedance of which lies between that of the ceramic of the transducer element and that of the coupling medium, is provided between the transducer elements and the coupling medium. The thickness d of the layer is chosen in accordance with the relationship d>.tau..sub.k .multidot.c.sub.LA, where .tau..sub.k is the propagation time of sound in the piezoceramic of the transducer elements and c.sub.LA is the sound velocity in the intermediate medium.

    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.

    Abstract: A device for spatial location and destruction of concretions in bodily cavities by application of pulsed ultrasonic shock waves generated by a shock wave transducer focussed on the concretion in question, the shock waves being transmitted to the patient by a coupling fluid. This transducer may also be operated under reduced power if appropriate during the locating operation, as an A-scanner, according to the pulse echo mode. A B-section image of the bodily tissue traversed by the ultrasonic field is generated on a monitor by means of at least one B-scanner, so that the concretion present in the section image may be placed in coincidence with a target mark present on the monitor and indicating the position of the transducer focus by a relative displacment between the patient and the device, and the shock wave transducer may thereafter be placed in operation under corresponding high power for destruction of the concretion. A support carrying the B-scanner is displaceable with respect to the symmetry axis of the shock wave transducer during the locating operation, so that it is possible to have a plurality of different section images and thus a high degree of spatial resolution of the section scanned during the locating operation.

    Abstract: An instrument for ultrasonics lithotripsy comprises a probe which is applied to the stone which is to be disintegrated, which may be placed in oscillation by means of a piezo-electric sound transducer which is assembled from ceramic discs. The transducer is energized into oscillation by an electrical generator and the transducer oscillations are transmitted to the probe via a distal transducer closure. A particularly effective operation of the instrument is the result if the transducer is energized only intermittently by pulsed operation of the generator, no specific natural resonance frequencies of the system being intended to occur within the preset range of operating frequency.
