    摘要： A stent-graft having an exo-skeleton attached to a tubular graft, the tubular graft having a peripheral wall defining a lumen therein extending between first and second ends. One or more support elements, defining the exo-skeleton, are attached to the tubular graft, each support element extending generally peripherally around the tubular graft, each support element including generally axial segments and generally peripheral segments. A plurality of first fasteners attach the plurality of support elements to the wall of the tubular graft, at least one generally axial segment being slidably engaged by each first fastener. A plurality of second fasteners also attach the plurality of support elements to the wall of the tubular graft, each second fastener substantially anchoring a generally peripheral segment of the respective support element to the wall of the tubular graft. The stent-graft also includes first and second stents on the first and second ends for substantially anchoring the respective ends within a body passage.

    摘要： An apparatus for sealing a puncture extending through tissue to a blood vessel includes a guidewire including an expandable tamp, a retaining sheath for covering the tamp, and a delivery sheath including a primary lumen for receiving the guidewire therethrough and a secondary lumen for delivering sealing compound into the puncture. The guidewire is advanced into the puncture with the tamp in a contracted condition, the tamp is expanded within the vessel after retracting the retaining sheath, and the guidewire is retracted to seal the puncture from the vessel. The delivery sheath is advanced over the guidewire, and sealing compound is introduced into the puncture through the delivery sheath. After introducing the sealing compound, the delivery sheath is removed, and an introducer sheath is advanced over the guidewire to provide access to perform a medical procedure via the vessel after removing the guidewire.

    摘要： A vascular filter is provided that includes a tubular member having proximal and distal ends, and a guidewire lumen. An expandable frame is attached to the tubular member capable of assuming collapsed and enlarged conditions, and filter material is attached to the frame, the filter material having an open proximal end when the frame assumes its enlarged condition. An apparatus for recovering a vascular filter from a blood vessel is also provided that includes a sheath and a retrieval member deployable from the sheath. The retrieval member includes a connector on its distal end for securing the tubular member, such as an expandable member within a recess for receiving the tubular member. The vascular filter may be constrained in its collapsed condition in a sheath, and the tubular member advanced over a guidewire to a location downstream of a treatment site. The vascular filter is deployed and expanded to its enlarged condition across the blood vessel, the guidewire remaining in place. A procedure is performed at the treatment site, the vascular filter capturing released emboli. The retrieval device is advanced over the guidewire, the vascular filter is secured to the retrieval member, and the vascular filter and retrieval device are withdrawn from the blood vessel.

    摘要： Apparatus is provided comprising a coiled sheet having a plurality of flaps mounted on its interior surface that project radially inward into a lumen formed by the interior surface of the apparatus when it is deployed. The flaps lie parallel to the interior surface of the sheet during transluminal delivery, but project radially inward once the apparatus is deployed. The flaps may comprise a fine mesh for use as a filter, or alternatively may be covered with a biocompatible material that is substantially impermeable, so as to partially or completely occlude the lumen. In a further alternative embodiment, the flaps may comprise a resilient biocompatible plastic or polymer, so that the flaps move in response to the flow and function as a pressure-based or directional valve.

    摘要： Apparatus and methods are provided for use in filtering emboli from a vessel and performing thrombectomy and embolectomy, wherein a vascular device comprises one or more support hoops, each having an articulation region connected near a distal end of a guide wire, and a blood permeable sac affixed to the support hoop or hoops to form a mouth of the blood permeable sac. The mouth of the sac closes when the apparatus is collapsed for removal to prevent material from escaping from the sac.
