About Novadaq Technologies Inc:
Novadaq Technologies develops and markets real-time fluorescence imaging technologies for use in the operating room. The Company's core technology platform, SPY imaging, provides clinically relevant, anatomic and physiologic images during a wide variety of complex open and minimally invasive surgical ("MIS") procedures. SPY empowers surgeons treating life-threatening illnesses such as breast, colon and other cancers and cardiovascular disease to more effectively treat vascular blockages and assess tissue perfusion. More than 40 peer-reviewed publications demonstrate that SPY imaging leads to fewer post-operative complications and reduced hospital costs. The SPY imaging System is cleared by the United States Food and Drug Administration ("FDA") for real-time use during open and MIS surgical procedures. The endoscopic SPY System combines all of the capabilities of SPY imaging with state-of-the-art high definition ("HD") visible light visualization offered by conventional endoscopes. 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. The integrated system received FDA 510(k) clearance to market in February 2011. In addition, in September 2010, Novadaq entered into an exclusive North American sales and marketing alliance with LifeCell™ Corporation, a Kinetic Concepts ("KCI"), Inc. Company, for SPY in open plastic and reconstructive, gastrointestinal and head and neck surgery. Novadaq's cardiac surgery products, including SPY imaging for cardiac applications and a Heart Laser™ System targeted at improving heart surgeries, are marketed through a direct sales team.
