Apparatus for dispersing fluids for dissolution or concretions in a bodily cavity
First Claim
1. Apparatus for dissolving concretions within a bodily cavity of a patient to be treated, under the action of a solvent fluid in contact with bodily cavity fluid within said cavity, the apparatus comprising means for introducing a solvent fluid into said bodily cavity for mixture with said bodily cavity fluid, an ultrasonic transducer adapted for coupling to the exterior of the patient'"'"'s body, and being provided with means for emitting ultrasonic waves focussed on at least one of said fluids in said cavity, within a frequency range of from 20 to 40 kHz and having sufficient power to produce cavitation in at least one of said fluids to cause dispersion therebetween.

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.
