Abstract
An extracorporeal kidney stone disintegrator comprises an upwardly open ellipsoidal reflector having an open upper end. A spark gap is provided in said reflector at the first focus point thereof. A flexible waterproof shroud is fixed to the open end of the reflector and secured to the skin of a human body containing a concretion such as a kidney stone to be disintegrated. A body of water fills said reflector and said shroud and is in direct contact with the skin of said human body, the reflector being positioned relative to said body so that the concretion is at the second focus point of the reflector. Generation of a sprak across the spark gap causes generation of a shock wave focused on the concretion and coupled to the concretion by the body of water and by the tissues of the human body.
