Patent ID: 8771336

Claim:
An endoluminal prosthesis comprising: a graft having a tubular body comprising proximal and distal ends; a valve replacement disposed between the proximal and distal ends of the graft; at least one stent coupled to the graft, the at least one stent having a contracted delivery state and an expanded state for maintaining patency within a portion of the graft; at least one fenestration disposed in a sidewall of the graft at a location distal to the valve replacement; a first perimeter having a first diameter and surrounding the at least one fenestration; a band of flexible material attached to and surrounding the first perimeter and having a flexible frame; and a second perimeter attached to and surrounding the band of flexible material and having a second diameter greater than the first perimeter diameter; where the band of material has a first diameter substantially the same as the first perimeter diameter and a second diameter substantially the same as the diameter of the second perimeter, and where the diameter of the band of material decreases in a direction away from the surface of the graft from the second perimeter to the first perimeter, wherein the band of material is configured to independently move between an interior surface of the graft and an exterior surface of the graft, and wherein the flexible frame extends about a surface of the band from the first perimeter to the second perimeter.
