Stent graft with fenestration
First Claim
1. An endovascular prosthesis comprising:
- a tubular body having a wall and comprising a graft material;
a shaped protrusion extending from the wall and comprising a cured thermoset graft material formed into a curved shape, the shaped protrusion having an outer edge and an inner edge at least partially surrounded by the outer edge and being void of structures other than the thermoset material that extends radially between the edges; and
a fenestration having fluid communication through the wall and disposed within the inner edge of the shaped protrusion,wherein the shaped protrusion is semi-rigid.

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.
