Trial designed to evaluate effectiveness of RenalGuard(TM) in preventing

Contrast -Induced Nephropathy

FRANKLIN, Mass., Dec. 19 /PRNewswire-FirstCall/ -- PLC Systems Inc. (Amex: PLC), a company focused on innovative cardiac and vascular medical device-based technologies, announced today that it has named two lead investigators for the upcoming pivotal trial of its RenalGuard Therapy(TM). The lead investigators are Charles Davidson, MD, Professor of Medicine, Northwestern University Medical School and Richard J. Solomon, MD, Professor of Medicine, University of Vermont College of Medicine. The trial is designed as a multi-center, prospective, randomized controlled trial to evaluate the effect of RenalGuard(TM) in the prevention of Contrast-Induced Nephropathy (CIN) during cardiovascular and peripheral imaging procedures performed in a catheterization lab. PLC intends to begin enrollment in the RenalGuard Pivotal Trial in early 2008, following receipt of the necessary approval from the U.S. Food & Drug Administration.

"Contrast-Induced Nephropathy is the third most common cause of in- hospital acute renal failure," stated Dr. Solomon. "The data on current prevention methods is largely inconclusive. It is our hope that this study will help determine the preventative benefits of RenalGuard Therapy in clinical use."

Dr. Davidson added, "CIN is a major issue for at-risk patients undergoing imaging procedures and can result in longer hospital stays and higher mortality rates. A cost-effective, easy-to-use preventive measure could reduce costs and save lives."

RenalGuard is an investigational system and therapy that targets patients with compromised renal function who may be at risk for CIN. Renal
