Tensys® Medical Reports Significant Q1 Momentum

Non-Invasive, Continuous, Real-Time Blood Pressure Monitor Enjoying Rapid Clinical Adoption in Perioperative Markets.

San Diego, CA | June 1, 2004 -- Marking its first full year of commercial operations, Tensys® Medical, the leader in real-time, non-invasive blood pressure management, today announced it will shortly reach and pass the 100 customer milestone. Recent notable additions to the list of T-Line® users include: Sinai Hospital in Baltimore, Terrebone General Hospital in Houma, Louisiana, UCSD Medical Center in San Diego, Bayfront Hospital in St. Petersburg and Northside Hospital in Atlanta.

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.

"In direct contralateral comparison to an invasive A-Line we have found the T-Line® to be almost an exact match," commented Dr. Kelvin M. Yee, Department of Anesthesiology, Clinical Director Operating Rooms, Sinai Hospital of Baltimore. "Additionally, we have noted a number of bariatric patients in which the standard NIBP cuff was providing confusing and sometimes misleading information. I have come to trust the T-Line® over the cuff in the clinical management of my patients," continued Dr. Yee.

Dr. Rusty Tortorice, Chairman, Department of Anesthesia at Bayfront Hospital in St. Petersburg, Florida added, "We have had nothing but a positive experience with Tensys® and the T-Line®; the device itself is highly accurate, the clinical support staff is outstanding and the follow-up has been timely and complete."

"We are most encouraged with the T-Line®'s accelerating rate of clinical adoption," commented Michael J. Martin, C.E.O. of Tensys® Medical. "The T-Line® system is enjoying strong market adoption with bariatric, orthopedic and general surgery patients. Our customers are validating both the accuracy and clinical utility of the T-Line® via both their initial purchase and continuing, routine use of the system," continued Mr. Martin.

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.
