InfraReDx’s New LipiScan™ IVUS Coronary Imaging System to Be Highlighted at TCT 2010

– Interventional Cardiology Community Thought Leaders to Discuss Clinical Experience with LipiScan to Improve Stenting Safety and Patient Outcomes –

BURLINGTON, Mass. – September 17, 2010 – InfraReDx, Inc., a medical device company developing intelligent cardiovascular diagnostic imaging technologies, today announced that its new LipiScan™ IVUS Coronary Imaging System will be highlighted during the annual Transcatheter Cardiovascular Therapeutics meeting (TCT 2010). The novel device, which was recently cleared by the U.S. Food and Drug Administration (FDA), will be featured in scientific and clinical symposia, live case broadcasts, product demonstrations and poster abstract sessions. TCT 2010 is being held September 21-25, 2010 at the Walter E. Washington Convention Center (“the convention center”) in Washington, D.C. TCT is the world's largest educational meeting specializing in interventional cardiovascular medicine and showcasing the latest advances in techniques, therapies and clinical research.

The Company expects to conduct a broad commercial launch of the system within the U.S. by year-end 2010, and anticipates regulatory approval and launch in Europe during 2011.

The LipiScan IVUS system utilizes a novel multimodality imaging catheter; the first ever to combine the complementary technologies of near-infrared (NIR) spectroscopy and intravascular ultrasound (IVUS). This combination enables interventional cardiologists to rapidly determine both the structure of plaque (via IVUS) along with its chemical composition (via NIR spectroscopy). NIR spectroscopy is the only technology cleared by the FDA for the specific task of detection of lipid-core coronary plaques (LCP). Such plaques can adversely impact the safety of stenting and are associated with heart attacks that occur in those who have received stents and in the general population.

Dr. James Muller, founder and chief executive officer of InfraReDx, Inc. noted that the “LipiScan IVUS system is the culmination of a major effort to develop a single catheter that utilizes both light and sound to characterize coronary plaques. The novel near-infrared spectroscopic feature is an excellent means to identify lipid core plaque while the traditional ultrasound provides a picture of the plaque that is useful for stenting decisions.”  

Dr. Muller stated that “this new multimodality imaging system will provide the interventional cardiologist with additional information about the extent of atherosclerosis within the coronary artery that will help assess the level of risk of stenting procedures. We are pleased to present this breakthrough technology at TCT, the annual meeting for discussion of major advances in interventional cardiology.” 

The LipiScan IVUS system will be featured in many sessions at TCT 2010.

About the LipiScan™ IVUS Coronary Imaging System
The LipiScan IVUS Coronary Imaging System is the world’s only intravascular imaging system that combines co-registered grayscale intravascular ultrasound (IVUS) together with InfraReDx’s proprietary near infrared (NIR) lipid core plaque (LCP) detection technology. The LipiScan IVUS system delivers all the benefits of IVUS plus the lipid core plaque detection power of NIR spectroscopy to help physicians optimize their stenting strategy. The system was designed by cardiologists for cardiologists and provides an unparalleled "one-stop" visual determination of critical coronary health features to assist in the care of coronary patients, including the identification of lipid-core plaques, degree of stenosis, reference vessel diameter, and plaque burden. This information also aids in facilitating proper stent sizing and placement, and in verifying full stent expansion and apposition and may also help guide post-intervention medical therapy. The innovative design enables cardiologists to generate and display the combined Chemogram™/IVUS analysis immediately upon completion of the single catheter pullback.

Coronary Stenting Statistics
Each year, more than 2 million individuals worldwide undergo coronary stenting. While clinical results of stenting procedures have steadily improved, approximately 30% of individuals undergoing stenting experience a significant adverse event such as peri-stenting myocardial infarction, post-procedure complications from the stented site, or new coronary events at non-stented sites. In most cases, stenting is guided primarily by X-ray angiography, which does not reveal the health of the vessel wall. Increasingly, physicians are recognizing the limitations of relying on angiography alone and are turning to advanced imaging solution systems to optimize stenting strategy.
