International Classification:

A61M 29/00

US Classification:

606200000

Abstract:

A device for delivering an occlusive element includes an elongate sheath having a lumen therein. An elongate core member is disposed within the lumen and is formed from a proximal portion and distal portion connected via a joint. The distal portion of the elongate member includes a severable junction secured to the occlusive element. A marker coil is coaxially arranged around the distal portion of the elongate core member and is partially disposed inside the sheath lumen. A coil member is coaxially arranged around the distal portion of the elongate core member and coaxially arranged around at least a portion of the marker coil extending outside the lumen of the sheath. The coil member is secured at a distal end thereof to the distal portion of the elongate core member. The device resists axial compression while allowing for radial bending.

A61F 2/07
A61F 2/90

Abstract:

A tissue lumen stent is provided with a body having an elongated tubular configuration and a foreshortened configuration. In the foreshortened configuration, downstream and upstream ends of the body expand radially into downstream and upstream flange structures, leaving a generally cylindrical saddle region therebetween. In some embodiments, the flange structures are non-symmetrical with respect to one another. Systems and methods of using the stents are also disclosed.
