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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
