Abstract
An endovascular prosthesis and method of constructing a prosthesis device for implantation into the lumen of a body vessel. The endovascular prosthesis includes a fenestration in the device surrounded by an inner edge, and the inner edge further surrounded by an outer edge of larger diameter. A shaped protrusion of semi-rigid graft material spans the distance between the inner edge and the outer edge connecting the two edges. The shape protrusion has a surface area larger than the plane of the tubular body between the edges and therefore will have excess material. This excess material allows the inner edge and the fenestration to move within the circumference of the outer edge. The shaped protrusion may also form a semi-rigid dome.
