Abstract:
1. A prosthesis, comprising: a graft having a tubular body and a surface comprising a first biocompatible material; at least one fenestration having a diameter extending from a sidewall of the graft; a first perimeter having a first diameter and surrounding the fenestration; a band of flexible material surrounding the first perimeter and having a flexible frame disposed about a surface of the band, the flexible frame having a plurality of support units; a second perimeter in the sidewall 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; where each fenestration is pivotable in any direction away from an axis perpendicular to a longitudinal axis of the prosthesis, where 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 plurality of support units extend about the surface of the band from the first perimeter to the second perimeter.
