About Novadaq Technologies Inc.

Novadaq Technologies develops and markets real-time fluorescence imaging technology products for use in the operating room. The company’s primary core technology platform, SPY Imaging, provides clinically relevant, anatomic and physiologic images during a variety of complex open and minimally invasive surgical (MIS) procedures. SPY empowers surgeons treating life threatening diseases to more effectively treat vascular blockages; assess tissue perfusion; identify cancerous tumors and delineate margins; and visualize relevant lymph nodes for removal. More than 30 peer-reviewed publications demonstrate that SPY imaging leads to fewer post-operative complications and reduced hospital costs. The endoscopic SPY system (a SPY scope) combines all of the capabilities of SPY imaging with state-of- the- art high definition (HD) white light visualization offered by conventional endoscopes. The company’s key markets include plastic reconstructive, gastrointestinal, cardiac and general surgery. To realize the full potential of its technology platform, Novadaq explores technology alliances. Novadaq announced its first alliance with Intuitive Surgical Inc. in January 2009, to integrate SPY imaging into the 3-D HD imaging capabilities of the da Vinci® Surgical Robotic System. In addition, Novadaq is the exclusive United States distributor of PLC Medical’s CO2 HEART LASER System. For more information, please visit the company’s website at http://www.novadaq.com.
