Abstract
An endoluminal prosthesis comprises a graft having a tubular body comprising proximal and distal ends, and a valve replacement disposed between the proximal and distal ends of the graft. At least one stent is coupled to the graft and has a contracted delivery state and an expanded state for maintaining patency within a portion of the graft. At least one fenestration is disposed in a sidewall of the graft at a location distal to the valve replacement. In one embodiment, the at least one fenestration is pivotable in any direction away from an axis perpendicular to a longitudinal axis of the prosthesis.
Claims16
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.
