Novadaq Receives U.S. Patent for Intra-Operative Imaging Procedure Using the SPY System

TORONTO, ONTARIO--(Marketwire - July 12, 2005) - Novadaq Technologies Inc. (TSX:NDQ) today announced that it has been granted a patent by the United States Patent and Trademark Office for the SPY™ Intra-operative Imaging System (SPY System). The SPY System enables real-time visual confirmation of revascularization during heart bypass surgery thereby allowing bypass graft technical errors to be detected and corrected while the patient is still in the operating room.

"The claims of this patent provide protection for our proprietary SPY System technology and our intra-operative imaging procedure," said Arun Menawat, President and CEO of Novadaq Technologies. “This U.S. patent supports our global strategy to build a strong IP portfolio to protect our innovative vascular imaging technology products and emerging pipeline.”

The patent, U.S. 6,915,154 B1, is titled "Method and Apparatus For Performing Intra-Operative Angiography" and describes the SPY intra-operative fluorescent imaging system that enables cardiac surgeons to confirm the location of coronary arteries during coronary artery bypass graft (CABG) procedures and visually assess and validate the functionality of bypass grafts.

About the SPY Intra-operative Imaging System

Novadaq’s SPY Intra-operative Imaging System has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for use during CABG surgery. The SPY System is the first intra-operative fluorescent imaging system that enables cardiac surgeons to confirm the location of the coronary arteries and assess bypass graft functionality during coronary artery bypass procedures. The SPY System enables the surgeon to view, record, replay, print and archive high quality real-time images of the coronary arteries and bypass grafts.
