French medical device maker EDAP TMS SA said Wednesday the U.S. Food and Drug Administration has approved an ultrasound device that dissolves kidney stones.
EDAP's Sonolith I-Sys robotized device combines ultrasound and X-ray systems to treat urinary stones, company officials said.
The device was approved in Europe and launched in late 2007. EDAP has no U.S. launch date.
The company's U.S.-traded shares climbed 83 cents, or 61 percent, to $2.20 in Wednesday afternoon trading.
