  • DOUBLE LOADED STENT DELIVERY SYSTEM
    Publication number: 20090138065
    Abstract: A delivery system that is preloaded with a sleeve member and a metallic stent and method of delivery of the sleeve member and stent at a target stricture site are described. The method of delivery occurs in two stages. The first stage involves deployment of the sleeve member and the second stage involves deployment of the metallic stent within the interior region of the sleeve member. The sleeve member may be formed from a shape memory plastic which may also be biodegradable. The delivery system provides a method of deploying a covered stent that would not otherwise be possible because of limited introducer space.
