The WallFlex Biliary RX Fully Covered Stent System RMV is the first and currently the only metal stent cleared in the U.S. for the treatment of benign biliary strictures secondary to chronic pancreatitis with indwell up to 12 months. Patency, or the ability for a stent to remain open and unoccluded, is a crucial characteristic of any Self-Expanding Metal Stent (SEMS). An FCSEMS with relatively high radial force (VIABIL stent and WallFlex stent) showed no migration, while the Niti-S series showed a high migration rate.
