Mauna Kea Technologies Announces Strong Presence at Digestive Disease Week 2007

PARIS and WASHINGTON, May 17 /PRNewswire/ -- Mauna Kea Technologies (MKT), a leader in the field of in vivo cellular imaging for biomedical research and clinical practice, today announced that five oral presentations and eight posters on MKT's Cellvizio(R)-GI will be presented at the Digestive Disease Week(R) (DDW) 2007 conference taking place in Washington, D.C., May 19 to 24. Cellvizio(R)-GI is the Company's technology platform for gastrointestinal applications that enables real-time viewing of tissues at the microscopic level.

Cleared by the U.S. Food and Drug Administration in September 2005, Cellvizio(R)-GI is the first and only confocal endo-microscopy instrument that is compatible with all endoscopes and allows real-time, dynamic imaging of the mucosa at 12 frames per second. To date, more than 400 patients have undergone a procedure with the Cellvizio(R)-GI imaging system.

"Endo-microscopy performed with confocal miniprobes(TM) has the potential to improve our ability to diagnose, monitor and treat patients with Barrett's Esophagus," said Kenneth Wang M.D., Mayo Clinic, Rochester, MN. "We are looking forward to exploring additional applications of this exciting technology."

Sacha Loiseau, Ph.D. president and CEO of Mauna Kea Technologies, said, "The breadth of international clinical data presented here at DDW underscores the utility of Cellvizio(R) in a range of clinical applications including surveillance of Barrett's Esophagus, ERCP and even in the emerging field of Natural Orifice Transluminal Endoscopic Surgery (NOTES). Cellvizio(R)-GI is now being used routinely at some of the world's major academic centers and we believe that the level of data presented at this year's DDW will encourage wider use of our technology."

   DDW clinical data highlights include:    Poster Session:     "Laser Confocal Microscopy (LCM) as a Guide for                       Endoscopic Mucosal Resection (EMR) in Barrett's                       Esophagus"   Lead Investigator:  Kenneth Wang, M.D., Mayo Clinic, Rochester, MN   Date/Time:          Sunday, May 20, 2007 from 8:00 AM - 5:00 PM   Location:           Hall E (Washington Convention Center)    Clinical Symposium: "Advancing Image Guided Intervention in the Colon"   Lead Investigator:  Thomas Wang, M.D., Stanford University School of                       Medicine   Date/Time:          Monday, May 21, 2007 -- 5:06 PM   Location:           Room 152 (Washington Convention Center)    Oral Presentation:  "In Vivo Identification of Colonic Dysplasia Using                       Peptide-Mediated Confocal Fluorescence Microscopy"   Lead Investigator:  Pei-Lin Hsiung, M.D., Stanford University School of                       Medicine   Date/Time:          Tuesday, May 22, 2007 -- 2:30 PM - 2:45 PM   Location:           Room 101 (Washington Convention Center)    Oral Presentation:  "In-vivo Histopathology via Standard Endoscopes?
