摘要:
An elastomeric radiopaque adhesive composition which includes a biocompatible elastomeric matrix and a radiopaque material distributed therein in sufficient amounts to produce a radiopaque image. Further, a hybrid vascular prosthesis including a PTFE structure, a textile structure and a cured elastomeric bonding agent adhesively secures the PTFE to the textile. The elastomeric agent having radiopaque material impregnated therein in sufficient amounts to produce a radiopaque image.
摘要:
A prosthesis anchor is adapted to convert a previously untreatable anatomy into a more typical and treatable condition. Preferably, the anchor is adapted to be transported endoluminally to a deployment site in a body lumen. The anchor includes a landing section for securing the anchor at a relatively fixed position in the lumen, and a docking section adapted to receive a mating prosthesis the landing section of the anchor may be permanently affixed to the lumen by a variety of mechanical and/or adhesive fixation means.
摘要:
A variable length endovascular prosthesis adapted to prevent endoleaks is provided that includes a substantially tubular first graft member having an interior surface, an exterior surface, and a proximal end, and a substantially tubular second graft member slidably engaged coaxially within the first graft member. The prosthesis further includes a substantially tubular fluid-tight connecting member attached at one end to the first graft member and attached at another end to the second graft member. The connecting member is axially compressible and expandable to facilitate engagement of the second graft member within the first graft member while maintaining a seal between the graft members.
摘要:
A graft system for intraluminal delivery in a vessel in need of repair comprising a graft, anchoring means, and a strippable sheath around at least part of the graft. A preferred anchoring means is a balloon-expandable stent. Also included in the invention is a method of using the device to treat a body lumen. The strippable sheath is removable by pulling on a drawstring to remove it which permits expansion of the graft. The positioning of the device may then be adjusted prior to stent dilation. A preferred embodiment of the invention includes a bifurcated graft system for intraluminal delivery in an aortic aneurysm comprising a bifurcated graft having a distal region and two legs, an expandable stent disposed in part of the distal region, and a strippable crocheted sheath around the distal region and one of the two legs. The strippable crocheted sheath is removable by untying it to permit expansion of the graft after initial placement within the aneurysm.
摘要:
A self-expanding endoluminal device comprising a tubular filamentary member having a hollow core for receiving a guidewire, the tubular member having a straightened configuration with the guidewire in the hollow core, a shape memory configuration without the guidewire in the hollow core, and an extension, optionally severable, accessible from outside of the body. The hollow core may be adapted to contain and elute or permanently contain a substance, which may be injected through the extension. A delivery system includes the guidewire, and a deployment method includes deployment with a proximal end of the extension accessible from outside of the body.
摘要:
A stent is provided that includes at least two stent segments which mate with one another. At least one of the stent segments includes a hollow member, and at least one of the stent segments includes a solid member. At least one of the solid members is secured to at least one of the hollow members.

A variable length endovascular prosthesis to prevent endoleaks includes a substantially tubular first graft member having an interior surface, an exterior surface, and an open end, and a substantially tubular second graft member engaged coaxially within the first graft member, the second graft member having a proximal end. The prosthesis further includes a substantially tubular fluid-tight connecting member attached at one end to the first graft member and attached at another end to the second graft member, where the connecting member is axially compressible and expandable to facilitate engagement of the proximal end of the second graft member within the first graft member while maintaining a seal between the proximal end of the second graft member and the open end of the first graft member.
