  • Patent number: 8540764
    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.

  • Patent number: 7972370
    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.

  • Publication number: 20090264990
    Abstract: A tubular synthetic endoluminal graft having at least one radiopaque ink marker pattern to radiographically delineate the surface of the graft cloth. The radiopaque ink marker includes a matrix of ink dots defining an annular band about a circumference of the graft. The endoluminal graft including at least one stent attached to the graft. The at least one stent may overlap or be positioned adjacent the radiopaque ink marker. The radiopaque ink marker may be utilized to facilitate creation of a fenestration in the side wall of the graft in situ to perfuse a side branch vessel.
