-- Device Offers a New, Non-Invasive, Accurate, Absolute Measurement of Cerebral Tissue Oxygenation --

Branford, CT – December 28, 2005 – CAS Medical Systems, Inc. (Nasdaq: CASM) announced today that it has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) to market its Near Infrared Spectroscopy (NIRS) Adult Cerebral Oximeter Monitor. The Oximeter is a continuous, non-invasive monitor measuring absolute levels of brain tissue oxygen saturation. The Company plans to launch the product in late 2006.

The CAS Cerebral Oximeter utilizes the company’s patented, optically-based NIRS technology which was developed with the help of a series of Small Business Innovative Research (SBIR) grants from the National Institutes of Health (NIH). Results from a study conducted by Duke University Medical Center, Durham, NC, detailing the performance of the CAS Oximeter were presented at the American Society of Anesthesiologists (ASA) Annual Meeting in October 2005.

"This is an important milestone for our company," said Louis P. Scheps, President and CEO of CAS Medical Systems, Inc. "Our initial market for this product will be in the Operating Room for use in high risk procedures such as cardiac surgery, carotid surgery and neurosurgery. The CAS Oximeter will give healthcare providers absolute, accurate, real-time information to guard against neurological injuries due to compromised brain oxygenation that can occur during many surgical and clinical procedures. We believe it may also assist in important clinical decisions in post-operative intensive care units.”
