PLC Systems, Inc. Reports First Quarter 2007 Results

FRANKLIN, Mass., May 3 /PRNewswire-FirstCall/ -- PLC Systems Inc. , a company focused on innovative cardiac and vascular medical device-based technologies, today reported financial results for the three months ended March 31, 2007.

First quarter 2007 total revenues were $1,493,000 compared with $1,889,000 in the first quarter of 2006. The net loss for the first quarter of 2007 was $686,000, or $0.02 per diluted share, compared to net income of $1,291,000, or $.0.04 per diluted share, in the first quarter of 2006, a period which included a $1.4 million gain on the sale of the company's Optiwave disposable manufacturing rights to Edwards Lifesciences Corporation.

"The first quarter of 2007 marked a significant turning point for PLC, as we changed the exclusive marketer and distributor for our TMR business in the U.S. from Edwards to Novadaq Technologies, Inc., a public company listed on the Toronto Stock Exchange," said Mark R. Tauscher, president and chief executive officer of PLC Systems. "This transition occurred late in the quarter, and obviously affected our first quarter results to some degree. We are very pleased, however, with the initial response from Novadaq's recently expanded US sales force to our TMR business, and are encouraged by their integrated approach to heart surgeons combining Novadaq's innovative SPY(R) Intra-Operative Imaging System with TMR. Already, we have learned that heart surgeons in the field are utilizing them together to gain both the diagnostic and therapeutic benefits that they provide. This market opportunity will be important in enabling future sales growth in TMR by Novadaq's sales team, and we look forward to working closely with Novadaq to capitalize on it."

Mr. Tauscher added, "Also during the first quarter of 2007, we announced the treatment of the first patients enrolled in our pilot trial for our RenalGuard Therapy(TM), which is designed to prevent Contrast Induced Nephropathy (CIN). We remain very enthusiastic about the market opportunity for RenalGuard(TM) in enabling at-risk patients to avoid CIN. These at-risk patients are believed to constitute some 15-20 percent of all patients undergoing the approximately seven million imaging procedures worldwide each year. We continue to make progress both in qualifying additional sites as part of our pilot trial as well as in laying the groundwork for our application to secure a CE Mark in Europe, which would allow us to begin our initial distribution in that region later this year."

During the first quarter of 2007, PLC shipped 3 new CO2 Heart Lasers (HL2) to U.S. hospitals through Novadaq. PLC ended the first quarter of 2007 with 158 HL2 CO2 Heart Lasers located at heart centers throughout the U.S. Also during the first quarter of 2007, a total of 457 disposable kits were shipped worldwide by Edwards, Novadaq and PLC. Edwards and Novadaq delivered 452 of these kits to U.S. hospitals and PLC shipped five disposable kits to international customers. In comparison, a total of 506 disposable kits were delivered worldwide during the first quarter of 2006.

Cash and short term investments at the end of the first quarter of 2007 totaled $10,077,000, up from $10,034,000 at the end of December 2006.
