Abstract:
An endovascular prosthesis includes a tubular body and a mobile external coupling. The tubular body includes a graft material and stents coupled thereto, a forms a lumen therethrough. The mobile external coupling extends outwardly from the tubular body. The mobile external coupling includes a graft material and is generally frustoconically shaped. The mobile external coupling includes a base coupled to the tubular body, a top spaced from the tubular body, and a coupling lumen disposed between the base and the top, wherein the coupling lumen is in flow communication with the body lumen. The coupling graft material is a woven fabric with warp yarn which run generally parallel to a longitudinal axis of the mobile external coupling including a shape memory material.
Abstract:
A method includes covering an ostium of a branch vessel emanating from a main vessel with a proximal landing zone of a high metal to vessel ratio landing zone stent-graft, wherein a metal to vessel ratio of the proximal landing zone when deployed is sufficiently high to encourage tissue ingrowth around the proximal landing zone yet is sufficiently low to ensure perfusion of the branch vessel through the proximal landing zone. The method further includes covering an aneurysm of the main vessel with an exclusion zone of the high metal to vessel ratio landing zone stent-graft, the exclusion zone being formed of graft material. By forming the exclusion zone of graft material, excellent exclusion of the aneurysm is achieved.
Abstract:
To facilitate the widespread use of the RF plasma catheter to provide in situ fenestration of a main stent-graft, potential side-effects of the fenestration are ameliorated using an electrode from a family of electrodes. Specifically, a family of electrodes is provided so that for a particular application, an appropriate electrode can be selected.
Abstract:
A stent graft system and method of use includes a stent graft for fixation at an attachment site with graft material defining at least one opening having an opening perimeter; a support attached to the graft material; a guide rail attached around the opening perimeter; and a helical anchor having a plurality of coils with a point at one end. The plurality of coils are rotatable around the guide rail to cause the pointed end of the coils to penetrate the graft material and the adjacent tissue in contact with the stent graft to sew the stent graft to the attachment site.

The mobile external coupling includes a graft material, extends outwardly from the tubular body, and is generally frustoconically shaped. The mobile external coupling includes a base coupled to the tubular body, a top spaced from the tubular body, and a coupling lumen disposed between the base and the top that is in flow communication with the body lumen. An annular support wireform is coupled to the mobile external coupling, and is formed into a sinusoidal configuration having a plurality of opposing first crowns and second crowns, the first crowns of the support wireform extending around of the top of the mobile external coupling. The coupling graft material extending between the second crowns of the support wireform and the tubular body is unsupported.
Abstract:
A method includes covering ostai of branch vessels emanating from a main vessel and an aneurysm with an integrated mesh high metal to vessel ratio stent. The integrated mesh high metal to vessel ratio stent includes serpentine rings integrated with an integrated mesh having holes formed therein. A metal to vessel ratio of the integrated mesh high metal to vessel ratio stent is sufficiently high to encourage tissue ingrowth around the integrated mesh high metal to vessel ratio stent yet is sufficiently low to ensure perfusion of the branch vessels through the integrated mesh high metal to vessel ratio stent.

A coupling deployment device is coupled to the coupling graft material to provide an extension force to extend the mobile external coupling from a collapsed configuration against the tubular body to an extended position wherein the mobile external coupling extends from the tubular body.
