Abstract
An intraluminal prosthesis is provided for strengthening a main lumen and a branch lumen that branches from the main lumen. The intraluminal prosthesis can comprise two tubular grafts. The first tubular graft can have a flexible body with a fenestration. The second tubular graft can have a flexible body that is configured for intraluminal coupling to the fenestration of the first tubular graft. The flexible body of the second tubular graft can have an outer dimension that is about equal to an inner dimension of the fenestration of the first tubular graft. The second tubular graft can also have a terminal stent that curves outwardly from a proximal end of the flexible body of the second tubular graft, whereby the terminal stent acts to couple the second tubular graft to the first tubular graft.
