About PLC Systems Inc.

PLC Systems Inc. is a medical technology company specializing in innovative technologies for the cardiac and vascular markets.

PLC's newest product, RenalGuard, is approved for sale in the EU as a general fluid balancing device. The RenalGuard System consists of a unique, proprietary, closed loop, software-controlled console and accompanying single- use sets that can be used by physicians and nurses to balance patient fluid levels during a variety of medical procedures. With its automated matched fluid replacement capability, RenalGuard is intended to minimize the risk to patients of over- or under-hydration while also largely eliminating what can be an intensive and time consuming manual fluid balancing task for physicians and nurses.

Headquartered in Franklin, Massachusetts, 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 distribution within the EU.
