  • Patent number: 12508139
    Abstract: Stents useable for treating venous stenosis are disclosed. In embodiments, a stent is configured to be auxetic, expanding axially as it is expanded radially, to prevent the imposition of tension on portions of a blood vessel adjacent to the stented portion of the blood vessel, and thereby prevent a narrowing of the adjacent portions and improving luminal gain. The stent may include one or more cross members that are deformable axially, to allow the axial length of the stent to be adjusted while maintaining a constant diameter, and further to allow the stent to be curved to conform to vessel curvature.

  • Patent number: 9861517
    Abstract: An apparatus which includes a closure member and delivery systems for closing vessels in the body of a patient is disclosed. In one embodiment, the closure member is a hemostatic closure member having a cylindrical shape and an expandable volume on contact with fluids. The hemostatic member includes a functional passageway through the length of the member so that it may be mounted over a delivery catheter or wire guide for delivery against a vessel puncture or into another vacuslar environment, such as to fill an aneurysm sac. In another embodiment the closure member is a fallopian tube closure member which is deployed into the fallopian tube over a guide wire to prevent conception. The fallopian tube member includes a loop-shaped frame having barbs, a first layer of material, a binding wire, a second layer of material, and an expandable volume on contact with fluids.

  • Publication number: 20140148839
    Abstract: An absorbable and expandable closure member used to occlude or exclude a body lumen or cavity, such as a blood vessel, fallopian tube, duct, aneurysmal sac, etc., comprising a closure member comprising one of more sheets of a biomaterial that are rolled, stacked, or folded to form a multilayer construct of a generally cylindrical configuration for deployment through a delivery system, either as a singularly or part of a multiplicity of closure members. The biomaterial is derived from a source material, such as small intestinal submucosa or another remodelable material (e.g., an extracellular matrix) having properties for stimulating ingrowth of adjacent tissue into the biomaterial deployed within the bodily lumen. The closure member is deployed to the bodily lumen from a delivery sheath, cartridge, and/or over a inner guiding member, such as a wire guide or catheter.
