The SpyGlass direct visualization system is the first single-use, single-operator cholangioscopy (soC) system with two dedicated irrigation channels, an optic channel and a 1.2mm diameter therapeutic channel – all within the 10Fr (3.3mm) spyscope Access and Delivery Catheter that also provides 4-way tip deflection to facilitate steerability and maneuverability through small ducts. The single-operator system is intended for diagnosing pancreaticobiliary strictures using the SpyBite Forceps and for use with EHL and Holmium laser for large or difficult stones in the biliary system.
