Abstract: The invention provides a bifurcated endoluminal prosthetic assembly. The assembly includes a trunk body including a body lumen and at least one access port. At least one branch body is positioned adjacent the access port. The branch body includes a branch lumen in communication with the body lumen. The assembly further includes a ring including at least one connector operably attached to the branch body. The ring is sized to operably engage the trunk body. The ring retains the branch body adjacent the access port. The invention further provides a method of retaining a branch body adjacent a bifurcated endoluminal prosthetic assembly. A ring operably attached to the branch body is compressed. The ring is positioned within the endoluminal prosthetic assembly. The compressed ring is expanded into operable engagement with the endoluminal prosthetic assembly.

Abstract: An endoluminal prosthetic assembly includes a trunk body including first and second elongated branches. The trunk body and elongated branches include a bifurcated body lumen formed therein. The assembly further includes an extension cuff including a cuff branch and an access port. The extension cuff, cuff branch, and access port include a bifurcated cuff lumen formed therein. A portion of the extension cuff is retainably positioned within the trunk body. A portion of the cuff branch is retainably positioned within one of the elongated branches. The cuff lumen is in communication with the body lumen. A method of extending an endoluminal prosthetic assembly deployed in a bifurcated vessel is also provided. The assembly includes a trunk body including first and second elongated branches. A portion of a compressed extension cuff is positioned within the trunk body and the first elongated branch. The compressed extension cuff is expanded into operable engagement with the trunk body and the first elongated branch.
