International Classification:

A61M 2900

US Classification:

606200, 606127

Abstract:

A self-centering filter is useful for trapping blood clots, reducing their size and arresting their further migration from the vena cava into pulmonary circulation. The two-planar filter design is formed from a conical array of filter wires wherein two sets of filter wires are included, each set differing in length from the other. The filter wires diverge from a common apex at one end and extend radially outwardly therefrom to an attachment end attachable to the wall of a blood vessel such that the attachment ends of the first set of wires are anchored at a location spaced apart from the location of anchoring of the attachment ends of the second set, effecting a two-planar filter design. This establishes a single filtering element having two planes of contact with the vein wall which also provides for centering of the filtering element. At least one of the sets of wires contains barbs, e. g. hooks, for anchoring the filter to the inner venal wall.

Assignee:

Scimed Life Systems, Inc. - Maple Grove MN

International Classification:

A61F 2/06

US Classification:

623 111, 606194, 606200

Abstract:

A delivery system comprising an endoluminal device, an outer sheath that radially surrounds the endoluminal device, a pusher positioned at one end of the endoluminal device, and a linkage between the pusher and the outer sheath that coordinates movement of the outer sheath in a first direction with simultaneous movement of the pusher in a second direction opposite the first direction. This delivery system is particularly useful for endoluminal devices that foreshorten, and may comprise the outer sheath moving a first distance (d) and the pusher moving a second distance (d), where d/dis approximately equal to the foreshortening ratio. The delivery system of this invention enables a foreshortening device, such as a vena cava filter, or stent, graft, or combination thereof, to be deployed with its end in a precise deployment location without foreshortening causing the end to move from the deployment location as the stent expands.

International Classification:

A61F002/06

US Classification:

623/001150

Abstract:

An endoluminal device for implantation in a body lumen reduces movement or migration of the device after implantation by the use of barbs or barb assemblies. A first embodiment uses at least one barb assembly having first and second portions attached to an implant, such as a stent, and at either sides of a bend. The second portion is adapted to protrude radially inward when the implant is in the radially compressed configuration and radially outward when the implant is in its radially expanded configuration. A second embodiment uses a barb having a curved segment which is curved proximally and radially inwardly. A third embodiment utilizes at least one barb assembly having a wire with a length greater than the cell height of the implant across which it extends and a substantially uniform cross-sectional area. Methods for implanting such devices are also contemplated.
