BIS Biliary Stent (cSEMS)

The BIS self-expandable, large-calibre, fully covered and easily removable biliary stent is designed to be used in chronic Common Bile Duct (CBD) obstructions for allowing intra-luminal flow during long indwelling periods (up to 36 months). They are made from a super-elastic alloy (nitinol) and fully covered by a novel polymeric material intended to prevent tissue ingrowth and reduce risk of occlusion.  In addition there are specially designed proprietary end elements intended to minimise risk of reactive tissue proliferation. The anchored model has a low radial force sphincteric segment to minimise reflux. The anchored model can be inserted without papillotomy. Deployment of the BIS stent can be performed using the standard ERCP procedure or percutaneously (depending on the deployment system used).  The single wire stent construction makes removal simple and straightforward.
