Ingrowth Resistant Stent Design: closed cell design engineered for palliative treatment of common bile duct obstructions. Propriety Permalume® Covering, a durable silastic polymer, resists tumour ingrowth Product Information Guidewire may be locked and unlocked at any time during the procedure Outward radial pressure has been shown to gently maintain luminal patency and may reduce the need for repeat stenting procedures Halo™ Technology enhances fluoroscopic visualisation Clear transition zone incorporated for excellent endoscopic visualisation The stent can be reconstrained as long as the stent deployment threshold (identifiable by fluoroscopic markers) has not been exceeded* Two guidewires may be used for multiple stenting procedures . 24Fr and 30Fr lumen diameters engineered for excellent bile flow
