MINNEAPOLIS--(BUSINESS WIRE)--March 8, 1999--Clarus Medical Systems, Inc. has been issued patent number 5,857,961 effective January 12, 1999 for a Surgical Instrument for Use with a Viewing System. This patent, along with number 5,735,792 issued in April 1998, further enhance Clarus' patent portfolio for fiber optic technology used in minimally invasive surgery.

We have positioned ourselves with a complete line of endoscopy products that can be used in virtually any spinal surgery performed in the United States today," stated Tom Barthel, President and CEO. "Additionally," added Mr. Barthel, "Clarus' broad patent portfolio and FDA clearances have allowed Clarus to develop endoscopic systems for other medical device companies in a variety of medical fields including ENT, airway management, intracranial, vascular, dental, cardiac and OB/GYN."

The medical community is quickly recognizing the benefits of minimally invasive techniques for spine surgery including reduced trauma to the patient, local anesthetic and faster recovery. These factors often permit surgical intervention for patients that would not have been considered candidates for conventional surgical therapy due to medical histories, age or personal preference. With its continuing advancement of endoscopic technology, Clarus is contributing to and reinforcing the newest standards of cost effective medical treatments.
