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.
