•Developing obstructive biliary symptoms associated with an attack of acute pancreatitis
•Biliary stricture of malignant etiology
•Stricture within 2 cm of common bile duct bifurcation
•Known bile duct fistula or leak
•Subjects for whom endoscopic techniques are contraindicated
•Known sensitivity to any components of the stent or delivery system
•Symptomatic duodenal stenosis (with gastric stasis)
