Abstract (en)
[origin: US4655220A] The invention relates to an apparatus for the contactless fragmentation of a concrement present in the body of a living being. A shock wave generator is aimed at a target region in the body and includes a coil having the form of a spherical segment. In front of the coil is arranged a mating radiator element, which closes off a liquid filled space and generates therein a shock wave focused on the centers of curvature of the coil and element upon brief connection of the coil to a high voltage. The concrement to be fragmented is positioned to lie at these centers of curvature.
