N E W S R E L E A S E For information contact: Joni Morford, Communicore 714/721-8081 jmorford@communicore.com ELECTROSCOPE INTRODUCES SIMPLIFIED SYSTEM TO INCREASE PATIENT SAFETY DURING LAPAROSCOPIC ELECTROSURGERY FOR IMMEDIATE RELEASE.....November 18, 1996.....Boulder, Colo.....ElectroScope, Inc., (NASDAQ: ESCP) maker of the only safety system that eliminates the risk of stray electrical burns during minimally invasive monopolar electrosurgery, today announced the availability of its newest product: The Universal Active Electrode Monitoring (AEMª) Instrument System. Developed in response to surgical staff feedback, the Universal System will reduce set-up time and simplify installation of the company's patented AEM patient safety product, the Electroshield Monitoring System¨. Created specifically for use with the Electroshield monitor, the Universal System is an adaptable connection system that eliminates the need for multiple cord connector sets and provides for rapid connection of instruments within the sterile field. The system can provide shielding to other manufacturers' instruments, or it can be used with ElectroScope's interchangeable scissors, dissectors, and grasper jaw inserts. The Universal System reduces the number of steps necessary for surgical staff to connect the Electroshield monitor to the electrosurgical generator and instruments. Considering the complexity of pre-surgical preparation, this technology will provide easier application of the only safety system available for the most popular form of minimally invasive surgery in the United States. Roger C. Odell, President and Chief Executive Officer of ElectroScope, explained the advantages of the Universal AEM Instrument System. "The surgical staff will find this new system extremely user friendly and simple," Odell said. "The elimination of multiple cord sets and elaborate connection procedures will allow for easier monitor setup, making it easier than ever for surgeons and hospitals to protect patients against stray electrical burns during minimally invasive monopolar electrosurgery." The monopolar electrosurgical technique is currently used by 80 percent of surgeons during minimally invasive surgery because of its versatility and superior ability to cut and coagulate (clot) tissue. By the year 2000, minimally invasive surgery is predicted to account for 40 percent of all urological, 50 percent of all general, and 70 percent of all gynecological surgeries, making this one of the most rapidly expanding surgical procedures. However, due to the limited "keyhole" field of vision through the laparoscope during minimally invasive surgery, burns outside of the surgical site can go undetected when electrical energy escapes through damaged insulation or capacitive coupling--a phenomenon in which oscillating electrical fields can heat body tissue through intact insulation by alternately attracting and repelling ions that occur naturally in tissue. These stray burns can cause tissue injury and organ perforation, and if left untreated, they can result in peritonitis, hemorrhaging, and death. In a recently published survey taken at an American College of Surgeons meeting, 18 percent of laparoscopic surgeons reported that they personally had experienced complications during minimally invasive surgery due to the release of stray electrical energy, and 54 percent said they knew of another surgeon who had. ElectroScope created the Electroshield Monitoring System to address the risks associated with minimally invasive monopolar electrosurgery. This major development in electrosurgical patient safety uses a combination of electrical insulation and electronic monitoring to prevent the release of stray electrical energy outside the surgical site and notifies the surgeon if potentially dangerous electrical energy is present. The Electroshield Monitoring System is the only product available that completely eliminates the risk of stray electrical burns during monopolar electrosurgery and that can universally be applied to all monopolar electrosurgical procedures, offering all patients the same standard of care. ElectroScope, Inc., was founded in 1991 to address the risks associated with laparoscopic monopolar electrosurgery and to develop and market its patented electrosurgical safety system: Active Electrode Monitoring. In 1994, ElectroScope introduced the Electroshield Monitoring System, a major development in electrosurgical patient safety that prevents the release of stray electrical energy outside the surgical site. ElectroScope is located in Boulder, Colo., and employs 43 people. End of document.
