Boston Scientific's SpyGlass® Direct Visualization System Featured in Broad Range of Clinical Studies at Upcoming Digestive Disease Week®

Studies to be presented on safety and efficacy of SpyGlass System for diagnostic and therapeutic procedures throughout pancreatico-biliary system

NATICK, Mass., May 28 /PRNewswire-FirstCall/ -- Boston Scientific Corporation (NYSE: BSX) today announced that 14 abstracts and additional clinical data analyses involving the SpyGlass® Direct Visualization System will be presented at Digestive Disease Week® (DDW), which runs from May 30 to June 4 in Chicago.

"The impressive number of presentations on the SpyGlass System underscores the potential of this technology as a vital new tool in endoscopic procedures for diagnosing and treating pancreatic and biliary disease," said Michael P. Phalen, President, Boston Scientific Endoscopy. "Boston Scientific is dedicated to developing technologies and expanding indications that enhance the quality of life for patients, as demonstrated by our new pancreatic indication for the SpyGlass System, as well as the broad range of endoscopic innovations showcased at DDW."

Previously available for use only in the bile and hepatic ducts, Boston Scientific recently received clearance from the Food and Drug Administration to market its SpyScope® Access and Delivery Catheter for diagnostic and therapeutic applications during endoscopic procedures in the entire pancreatico-biliary system, including the pancreatic ducts. The SpyScope Catheter is used in conjunction with the SpyGlass Direct Visualization System. The system is intended to guide visualization and accessory devices throughout the pancreatico-biliary system, enabling physicians to diagnose and treat pancreatic cancer or pre-cancerous tissues.

The SpyGlass System is a single-operator system developed to overcome the challenges of traditional cholangioscopy systems and reduce the need for exploratory surgery. The SpyGlass System is designed to enable physicians to directly visualize the target site, obtain a diagnostic tissue sample with the disposable SpyBite® Biopsy Forceps, and deliver therapies such as laser and electrohydraulic lithotripsy (EHL).

Schedule of Key Podium and Poster Presentations (partial listing, all times are Central Time):

All posters are available from 8:00 a.m. - 5:00 p.m. in South Hall of McCormick Place.

  • Holmium-YAG Laser Lithotripsy in the Treatment of Difficult Biliary Stones Utilizing SpyGlass: a Multi-Center Experience (Poster Presentation)

          This multi-center cumulative study reports on the use of Holmium-YAG
          laser lithotripsy with SpyGlass cholangioscopy in the management of
          difficult intraductal biliary stones.  Five to ten percent of
          biliary stones are not amenable to standard endoscopic extraction
          techniques and while electrohydraulic and laser lithotripsy have
          been shown to be effective, they have been used sparingly.  The
          study reports that the SpyGlass System now permits for routine use
          of these technologies.  Lead author of the study is Sandeep Patel,

  • It Looks Like Cholangiocarcinoma -- But is it? Using SpyGlass for Diagnosis of Cholangiocarcinoma in Patients with Primary Sclerosing Cholangitis (Podium Presentation)

          This study is designed to evaluate the characteristics of bile duct
          lesions in patients with primary sclerosing cholangitis (PSC) using
          the SpyGlass System and compare them to the characteristics of
          cholangiocarcinoma (CC) found in the literature with the
          cholangioscopic findings in combination with histologic, cytologic
          follow-up results.  Patients with PSC are at increased risk of
          developing CC but the absence of symptoms and the lack of reliable
          diagnostic instruments for early detection of tumors contribute to
          the poor prognosis in patients.  Direct visualization of the biliary
          system is not yet a standard tool for excluding malignancy in bile
          duct stenoses, but certain cholangioscopic characteristics of CC
          have been described.  This podium presentation will be given by
          Alexander Dechene, M.D., Gastroenterology and Hepatology, University
          Hospital Essen, Essen, Germany, at 8:42-8:54 a.m. in Room S100 of
          McCormick Place.

  • Assessment of SpyGlass for Cholangioscopy and Pancreatoscopy in 102 Consecutive Patients (Poster Presentation)

          This study describes the performance, safety and utility of the
          SpyGlass System for peroral cholangioscopy and pancreatoscopy in
          patients at Beth Israel Deaconess Medical Center in Boston.  Peroral
          cholangioscopy and pancreatoscopy allow direct visualization of the
          bile and pancreatic ducts while being able to take site-directed
          biopsies and perform electrohydraulic lithotripsy.  Lead authors of
          the study are Ram Chuttani, M.D., and Douglas K. Pleskow, M.D.

  • POC Using a Disposable Steerable Single Operator Catheter for Biliary Stone Therapy and Assessment of Indeterminate Strictures - a Multi-Center Experience Using SpyGlass (Poster Presentation)

          A poster presentation reports the results of a prospective 297-
          patient, 15-center registry that studied the utility and performance
          of the SpyGlass System for peroral cholangioscopy (POC).  The
          international study was led by Yang K. Chen, M.D.

The SpyGlass Direct Visualization System will be available for demonstration at Boston Scientific's booth #734. The Company will also offer hands-on demonstration sessions in its Simulated Clinical Endoscopy Suites and at its booth stations for the following products: WallFlex® Biliary, Esophageal and Enteral Stents, Polyflex® Esophageal Stents, Radial Jaw® 4 Biopsy Forceps, Resolution® Clip, CRE™ Balloon Dilators, the RX Biliary System™ and the EndoVive® Enteral Feeding initial placement and replacement devices.
