Abstract:
1. An endovascular prosthesis comprising: a tubular body of a graft material, the tubular body defining a lumen and having an opening formed therein; a plurality of stents coupled to the tubular body; and a multi-leaflet coupling having a plurality of overlapping leaflets successively coupled to the tubular body around the opening, the leaflets defining a passageway that is in fluid communication with the lumen of the tubular body, wherein the leaflets in a non-deployed configuration lay flush with the graft material of the tubular body and partially cover the opening of the tubular body and wherein the leaflets in a fully deployed configuration extend radially outward from the graft material of the tubular body, and wherein a diameter of the passageway defined by the leaflets increases when the leaflets transform from the non-deployed configuration to the fully deployed configuration, wherein each of the plurality of leaflets overlaps an adjacent one of the plurality of leaflets in both the non-deployed configuration and the fully deployed configuration.
