          May 5, 2010 -- Westford, Mass. --
              LightLab Imaging, Inc., the pioneer and leader in the development
              of Optical Coherence Tomography (OCT) technology for vascular and
              other imaging applications, has received clearance from the U.S.
              Food and Drug Administration (FDA) for the C7-XR Imaging System
              and companion C7 Dragonfly Imaging Catheter. These products, incorporating
              LightLab's latest generation Frequency Domain OCT (FD-OCT™)
            technology, are currently approved in over 35 countries in Europe
              and Asia, and have been used by leading hospitals to perform high
              resolution imaging of vessel and lumen morphology in thousands
          of coronary interventions to date. The C7-XR Imaging System and the sleek, monorail style C7 Dragonfly Imaging Catheter create a high resolution 50 millimeter coronary scan in under 3 seconds without the vessel occlusion that was required by earlier generation OCT systems.  Thousands of data points are analyzed simultaneously at ultra-high speeds, providing unsurpassed intravascular resolution at 15 micrometers, roughly twice the size of a red blood cell. This breakthrough, non-occlusive, intravascular imaging technology allows the clinician to readily see and measure important vessel characteristics otherwise invisible or difficult to observe with older intracoronary imaging modalities. "The C7-XR Imaging System represents a significant step forward for intracoronary imaging," said
              Dr. Ik-Kyung Jang, M.D., Ph.D., Professor of Medicine at Harvard
              Medical School; Director, Cardiology Laboratory for Integrative
              Physiology and Imaging; physician at Massachusetts General Hospital,
              Boston, MA; and principal investigator for LightLab's U.S. clinical
                  study. "We were all amazed with the speed and simplicity of
                  the LightLab OCT procedure, and the clinical utility is truly
                  unique. I expect OCT to rapidly become the new intracoronary
                  imaging standard." "LightLab's C7-XR FD-OCT image resolution is extraordinary, but what is most fascinating about this technology is its ease of use and extremely fast image acquisition," said
                Dr. Marco Costa, MD, Ph.D., Professor of Medicine; Director,
                Interventional Cardiovascular Center; and Director, Center for
                Research and Innovation Harrington-McLaughlin Heart and Vascular
                Institute University Hospitals, Case Western Reserve University. "These
                features will enable optimization of drug-eluting stent procedures
                with unprecedented accuracy, potentially reducing the number
                of stents placed per patient by ensuring appropriate disease
                assessment and targeting. The physician armed with OCT will have
                the ability to see the lumen vividly from the inside giving us
                incredible information and the ability to treat sub-optimal results
                while the patient is still in the cath lab." "LightLab
                  has been delivering state-of-the art intracoronary OCT systems
                  to leading hospitals outside of the United States for over
                    5 years," said
                  David Kolstad, CEO of LightLab Imaging. "With our clearance
                  by the FDA, U.S. clinicians now have access to a fast and easy-to-use,
                  high-resolution imaging system. We believe C7-XR Imaging System
                  and C7 Dragonfly Imaging Catheter will enhance the diagnostic
                  information and procedural control available to U.S. clinicians.
                  We will begin offering the C7-XR Imaging System and the C7
                  Dragonfly Imaging Catheter immediately." LightLab
                    Imaging will demonstrate the C7-XR Imaging System and C7
                    Dragonfly Imaging Catheter in booth number 28 at the Society
                    for Cardiovascular Angiography and Interventions' 2010 Scientific
                    Sessions in San Diego, from May 5 to 8. LightLab's U.S. clinical study of the C7-XR Imaging System and C7 Dragonfly Imaging Catheter was conducted at three U.S. centers. The centers and the investigators were: - Massachusetts General Hospital: Ik-Kyung Jang, M.D., Ph.D.
