    摘要： A stent is disclosed and can include a stent body having a longitudinal axis. The stent body can also have a network of struts that can define a plurality of cells defined between interconnected struts. Each of the plurality of cells includes a major axis that is angled with respect to the longitudinal axis to form a cell angle, β.

    摘要： The present invention provides a patent foramen ovale (PFO) closure clip. The clips of the present invention include two closure members joined by at least two spaced central connecting members. Each of the at least two spaced central connecting members is attached to each closure member at a location on the periphery of the closure member. The clips are designed such that the at least two central connecting members extend through the inclined PFO tunnel and the two closure members compress the overlapping layers of septal tissue, i.e. septum primum and septum secundum, together to close the PFO tunnel. The clips of the present invention take various forms depending, in part, upon the distribution of force required to close a given PFO. Thus, in some embodiments, the closure members include arcuate peaks. In other embodiments, the closure members include loops. In still other embodiments, the closure members include prongs.

    摘要： A filter with translating hooks is described. The filter can include strut members having first and second struts connected by a connecting portion. A translating hook is disposed adjacent the connecting portion of the strut members, the hook including a first elongate member attached at one end to the first strut and a second elongate member attached at one end to a second strut, the opposite ends of the elongate members connected together to define a tip. The translating hooks are configured to bend toward a central axis of the filter when the filter is in a collapsed configuration for delivery to a blood vessel and recovery from a blood vessel, and away from the central axis of the filter when the filter is in an expanded configuration within a blood vessel such that the hooks engage a vessel wall.

    摘要： A blood clot filter includes a number of locator members and anchor members, each of the members tipped with a retainer encompassed within bio-resorbable cover material. Upon delivery into a blood vessel, the locator and anchor members position the filter near the vessel centerline. After a period of time, the bio-resorbable cover material resorbs, allowing the retainer on the members to penetrate and attach to the vessel wall. A method of implanting the filter includes delivering the filter into a blood vessel and allowing the bio-resorbable cover material to resorb so retainers on the members can engage the vessel walls.
