    摘要: A stent-graft system includes a graft member (30) and separate coupling stent (50) that are adapted to be delivered separately to a location within a patient's body where they are coupled to form a stent-graft composite in-situ. The system thus allows for serial introduction of the graft member (30) and coupling stent through an introducer sheath (10) providing access to the location, instead of being delivered as the composite assembly together, thus allowing substantially reduced size of the introducer sheath (10). Particular embodiments provide highly beneficial improvements for treating AAA's, allowing for Seldinger puncture access techniques versus the conventional highly invasive "cut down" access procedures required by conventional pre-formed AAA stent-graft composite systems.

    摘要: This invention is an intraluminal grafting stent (10) that includes a collapsible tube member (12) having a first end (14) and a second end (16). An outer wall (18) and an inner wall (20) extend between the ends. A first end wall (22) and a second end wall (24) extend between the outer wall and the inner wall. The outer, inner, first end and second end walls form a chamber (26). A permeable film layer (30) extends between the first end wall and the second end wall in the chamber. The film layer, outer wall, and end walls define a space (32). A composite material (34) is positioned in the chamber between the inner wall and the permeable film layer. An opening (40) is positioned in one of the end walls to allow for the introduction of a reagent (60) into the defined space. The reagent reacts with the composite material to cause the composite material to harden after the stent has been positioned in a blood vessel.

    摘要: Novel medical devices and uses thereof for lining a blood vessel and/or treating an aneurysm are disclosed herein. The device comprises a non-metallic expandable tubular structure, implantable in a body vessel and being made, at least in part, from a polymeric system characterized by a stiffness which changes upon stimulation under physiological conditions. Novel polymeric systems are further disclosed herein, which are configured to produce a polymeric material upon stimulation under physiological conditions, such that a stiffness of said polymeric material is higher than a stiffness of said system. Uses of polymer systems in the manufacture of a device are further disclosed.
