COHERENT TO BEGIN CLINICAL TRIALS ON LASER LITHOTRIPSY
COHERENT TO BEGIN CLINICAL TRIALS ON LASER LITHOTRIPSY PALO ALTO, Calif., June 17 /PRNewswire/ -- Coherent Inc.
(NASDAQ: COHR) announced today that it received clearance from the FDA to begin human trials on the use of the VersaPulse surgical laser for the treatment of urinary stones. This minimally invasive procedure involves using an endoscope and the laser to fragment urinary stones in the ureter. Stones located in the lower third of the ureter cannot be treated with extracorporeal shock wave lithotripsy.
Clinical trials will be conducted at four sites -- the University of California in San Francisco; St. Vincent's Hospital in Erie, Pa.; Shelby Medical Center in Shelby, Ala.; and Jefferson University Medical Center in Philadelphia. Dr. Douglas Johnson, professor of urology at the University of Texas at Houston who conducted the initial animal studies of the VersaPulse laser on urologic soft tissue and on lithotripsy, stated that, "although the results of our investigation are preliminary, we believe that this laser will become the urologists' laser of the future." According to Ted Belleza, director of marketing at Coherent, this latest development, together with the recent FDA approval for the use of the VersaPulse laser on soft tissue in urology, is a significant step toward Coherent's goal of providing the urologist with a single laser for all urologic applications, such as bladder tumors and urethral and ureteral strictures. The VersaPulse laser has been cleared for use in several other surgical applications. These include arthroscopic surgery of the knee, shoulder, elbow, ankle, wrist, and temporomandibular joint, percutaneous discectomy for the treatment of low back pain, and open and endoscopic general surgery. Other applications pending FDA clearance include intra-abdominal gynecologic surgery, endoscopic sinus surgery, and ophthalmic surgery. Coherent Inc. is recognized as a world leader in the design, manufacture and marketing of lasers and laser systems for medicine, science and industry. Please direct any questions to Robert J.
