Tensys® T-Line® Acquired by Major University and Teaching Hospitals Including Stanford, University of Illinois-Chicago, University of Florida and Northwestern

San Diego, CA | September 15, 2003 -- Tensys® Medical, the leader in real-time blood pressure management, today announced the addition of several major university and teaching hospitals to their roster of Tensys T-Line users. Those institutions acquiring multiple T-Line® systems consist of Stanford University Medical Center, the University of Illinois Medical Center at Chicago, Shands Hospital at the University of Florida (Gainesville), and the Northwestern University system in Chicago including both Northwestern Memorial Hospital and Northwestern Prentice Women"s Hospital.

The Tensys® T-Line® is an FDA-cleared medical device providing anesthesiologists better, more effective control over patient safety during surgery by allowing them to quickly monitor and manage blood pressure variations.

"During our clinical evaluation phase I was extremely impressed by the performance and accuracy of the Tensys® T-Line's non-invasive, real-time monitoring capabilities," stated J. Kent Garman, M.D., Associate Professor of Anesthesiology, Stanford University Medical Center. "Now that we have purchased the device and have completed the in-house training sessions conducted by the Tensys® clinical specialists I am observing an increase in staff utilization. The Tensys® T-Line® has exceeded our expectations," Dr. Garman continued. The Stanford University Medical Center was ranked among the top 20 of "America"s Best Hospitals" by U.S. News & World Report in 2002.

"As luminary university and teaching hospitals begin acquiring and using the Tensys® T-Line® we believe that physicians working on orthopedic, urologlical, and bariatric cases, for example, will quickly observe the benefits of non-invasive, real-time, continuous blood pressure monitoring. In particular, the traditional cuff is often ineffective in monitoring blood pressure during gastric bypass cases where patients are traditionally rather obese," said Michael J. Martin, chief executive officer, Tensys® Medical. "In this segment of the population, as well as numerous others, our customers are confirming the clinical utility of the T-Line® solution," continued Martin.

There are currently two primary methods used by anesthesiologists to monitor blood pressure during surgery. The T-Line®, via its continuous, real-time data, is far more effective than the traditional cuff method and has clinically equivalent accuracy to that of the arterial line (A-line). The Tensys device uses a transdermal pressure sensor to continuously yet non-invasively measure blood pressure at the radial artery.

Tensys® Medical will be demonstrating the Tensys® T-Line® at booth #808 at the American Society of Anesthesiologists Annual Meeting in San Francisco from October 11-15, 2003. For more information on the meeting, please visit www.asahq.org.

About Tensys® Medical

Tensys® Medical, Inc. is the leader in real-time blood pressure management. The Tensys® T-Line®, the company's lead product, was cleared by the FDA in November 2002 as a medical device providing anesthesiologists with a non- invasive, continuous real-time blood pressure management tool.

The Tensys® T-Line® measures a patient's blood pressure at the radial artery. It offers anesthesiologists better, more effective control over patient safety during surgery by allowing them to quickly monitor and manage blood pressure variations. The T-Line®, via its continuous, real-time data, is far more effective than the traditional cuff method and has clinically equivalent accuracy to that of the arterial line (A-line). The device is based on Tensymetry®, the company's proprietary and patented technology, for non-invasively extracting the continuous, beat-to-beat pressure waveform from the radial artery without the use of any external calibration device. The science of Tensymetry® is broadly protected and is the result of over six years of research and development. Prior to its official product launch in March 2003, the Tensys® T-Line® was tested in approximately 500 surgical cases nationwide.

Tensys® Medical is based in San Diego, California and was founded in November 1995. For more information, please visit the company's Web site at www.tensysmedical.com.
