Patent ID: 8506622

Claim:
An endovascular prosthesis comprising: a tubular body having a proximal end, a distal end, and a body lumen disposed between the proximal and distal ends, the tubular body including a body graft material and a plurality of stents coupled to the body graft material; and a mobile external coupling integral with the tubular body and including an extended configuration wherein the mobile external coupling extends outwardly from a side surface of the tubular body wherein the mobile external coupling is generally frustoconically shaped and 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 and wherein the mobile external coupling includes a coupling graft material; and a helically shaped stent coupled to the coupling graft material, wherein the mobile external coupling and the stent include a compressed configuration wherein the mobile external coupling and the stent are collapsed against an outside surface of the tubular body such that the mobile external coupling is disposed outside of the body lumen in the compressed configuration, and wherein the stent is configured to provide an outward force away from the tubular body such that the mobile external coupling pops out from the tubular body when released from a restraining force.
