EDAP TMS shocks the hell out of kidney stones and a few other things the human body can't crush on its own. The company develops, manufactures, and markets non-surgical medical devices that treat urological diseases. EDAP's line of lithotripters utilize shockwaves to pulverize kidney stones. The company's Ablatherm system incorporates a technology called High Intensity Focused Ultrasound (HIFU), in which ultrasound waves are used to destroy prostate cancer cells. The company is also developing HIFU for the treatment of other types of tumors. Key subsidiaries EDAP Technomed, Inc. and EDAP Technomed Co. Ltd. market the company's products to the US and Japan, respectively. EDAP TMS was established in 1979.
