PROBLEM TO BE SOLVED: To provide an endoluminal prosthesis comprising a valve replacement and at least one fenestration.SOLUTION: The endoluminal prosthesis comprises a graft having a tubular body that has 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 for conveying 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 its 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. |
