Abstract

A non-invasive method and apparatus for in situ disintegrating calculi in the body of a living being employ electromagnetic radiation generated by a transmission antenna. The electromagnetic radiation is highly focused at the location of the calculus to be disintegrated. The transmission antenna is matched to the body medium by a suitable dielectric material.
