(NYSE:BSX)

NATICK, Mass., May 16 /PRNewswire-FirstCall/ -- Boston Scientific Corporation (NYSE: BSX) today announced that results from an international, multi-center patient registry documenting the safety and clinical utility of the SpyGlass® Direct Visualization System will be presented at Digestive Disease Week® (DDW), which runs from May 17-22 in San Diego, CA. Registry results will be announced in three separate scientific oral presentations scheduled for Tuesday, May 20. In addition, a total of 15 abstracts on the clinical utility of the SpyGlass System will be presented at the conference, underscoring its widespread acceptance in physician practices.

The SpyGlass patient registry reports on clinical data from 296 patients at 15 U.S. and European medical centers who required peroral cholangioscopy (PO) for the treatment or diagnosis of biliary stones or indeterminate strictures with suspected pathology.

The SpyGlass System is the first single-use direct visualization system that requires only a single physician operator and provides four-way steerability in a four lumen single-use catheter. The catheter provides two dedicated irrigation channels in addition to a 1.2 mm working channel through which diagnostic and therapeutic devices can be used in the biliary ducts. The system includes a miniature 6,000-pixel fiber optic probe attached to a camera that provides physicians with a direct view of a patient's bile ducts, overcoming some of the visual challenges of conventional endoscopic retrograde cholangiography (ERC) procedures.

"We are excited that DDW provides an opportunity to highlight the safety and therapeutic benefits of the SpyGlass System at the one-year anniversary of its worldwide launch," said Michael P. Phalen, President, Boston Scientific Endoscopy. "We have received positive feedback from the GI community regarding the ability of the SpyGlass System to provide excellent direct visual access to the bile ducts. We have nearly 300 patients enrolled in our comprehensive patient registry, which enables us to build further evidence of the clinical utility of cholangioscopy using the SpyGlass System." Schedule of SpyGlass Patient Registry Presentations:
