摘要：
An endovascular prosthesis includes a tubular body and a mobile external coupling. The tubular body includes a graft material and stents coupled thereto, a forms a lumen therethrough. The mobile external coupling extends outwardly from the tubular body. The mobile external coupling includes a graft material and is generally frustoconically shaped. The mobile external coupling includes a base coupled to the tubular body, a top spaced from the tubular body, and a coupling lumen disposed between the base and the top, wherein the coupling lumen is in flow communication with the body lumen. A cylindrical sealing cuff of graft material is attached to and extends from the top of the mobile external coupling towards the tubular body within the coupling lumen. The sealing cuff is configured to contact a portion of a branch vessel prosthesis and thereby provides an elongated interference seal between the branch vessel prosthesis and the mobile external coupling.
