PLC SYSTEMS REPORTS FIRST QUARTER 2008 RESULTS

RenalGuard limited launch in Italy underway, with patients already treated

FRANKLIN, Mass., May 15, 2008 — PLC Systems Inc. (AMEX: PLC), a company focused on innovative cardiac and vascular medical device-based technologies, today reported financial results for the three month period ended March 31, 2008.

First quarter 2008 total revenues were $1,168,000 compared with $1,493,000 in the first quarter of 2007. The net loss for the first quarter of 2008 was $762,000, or $0.03 per diluted share, compared to a net loss of $686,000, or $0.02 per diluted share, in the first quarter of 2007.

Mark R. Tauscher, president and chief executive officer of PLC Systems, Inc., stated, “We have continued to make substantial progress on our RenalGuard™ program so far this year. In March, we received conditional approval from the U.S. Food & Drug Administration to begin our U.S. multi-center pivotal trial to study the effectiveness of RenalGuard in reducing the incidence of Contrast-Induced Nephropathy (CIN). This pivotal clinical trial is expected to continue through 2009. Meanwhile, we secured our first order for RenalGuard consoles and single use sets in Europe, as part of our limited launch in Italy that began in the first quarter.  Patients are already being treated by some of these early adopting hospitals, and we are eager to gauge market reaction to our new product.”

Mr. Tauscher added, “Our TMR business produced a modest sequential improvement in kit shipments in the first quarter this year.  Based upon our current penetration of the market as well as a tightening of capital spending by healthcare institutions, we believe that this business’ success going forward will be more dependent upon kits sales and services, where we see opportunity for growth, than in laser systems. While we believe the business is stable, we do expect variation in quarterly rates of kits sales and services, making evidence of clear progress more difficult to assess. We continue to believe TMR therapy adoption is positioned for long-term growth in the hands of our exclusive U.S. distributor, Novadaq Technologies, building upon the synergies between our TMR system and Novadaq’s SPY® Imaging Technology.”

During the first quarter of 2008, PLC shipped one new CO₂ Heart Laser (HL2) to a U.S. hospital through Novadaq, compared to three new HL2s shipped in the first quarter of 2007 through Edwards Lifesciences Corporation, PLC’s previous U.S. distribution partner. PLC ended the first quarter of 2008 with 170 HL2 CO₂ Heart Lasers located at heart centers throughout the U.S.

During the first quarter of 2008, 390 disposable TMR kits were shipped, consisting of 375 to hospitals in the U.S. by Novadaq, in addition to 15 kits shipped internationally by PLC. In comparison, a total of 372 and 457 disposable TMR kits were shipped worldwide during the fourth quarter of 2007 and the first quarter of 2007, respectively.

During the first quarter of 2008, PLC shipped 50 single use sets associated with its RenalGuard System internationally, along with five consoles, for its limited European launch of RenalGuard in Italy.

About PLC Systems Inc.

PLC Systems Inc. is a medical technology company specializing in innovative technologies for the cardiac and vascular markets. Headquartered in Franklin, Mass., PLC pioneered the CO₂ Heart Laser System, which cardiac surgeons use to perform CO₂ transmyocardial revascularization (TMR) to alleviate symptoms of severe angina. CO₂ TMR offers a treatment option for angina patients who suffer from severe coronary artery disease. The CO₂ Heart Laser is the world’s first TMR angina relief device cleared for commercial distribution by both the U.S. Food and Drug Administration and Japanese Ministry of Health, Labor and Welfare, and to obtain a CE Mark for European distribution.

The company completed a pilot clinical safety study of its RenalGuard Therapy™ and RenalGuard System™ and has received its CE Mark Certificate for RenalGuard System. PLC recently received FDA conditional approval to commence a U.S. pivotal trial to study the effectiveness of its RenalGuard Therapy and Renal Guard System in the prevention of Contrast-Induced Nephropathy (CIN). RenalGuard Therapy is designed to reduce the toxic effects that contrast media can have on the kidneys. This therapy is based on the theory that creating and maintaining a high urine output is beneficial to patients undergoing imaging procedures where contrast agents are used. The real-time measurement and matched fluid replacement design of the RenalGuard System is intended to ensure that a high urine flow is maintained before, during and after these procedures. This should allow the body to rapidly eliminate contrast, reducing its toxic effects. The RenalGuard System, with its matched fluid replacement capability, is intended to minimize the risk of over- or under-hydration.
