Mobile external coupling with internal sealing cuff for branch vessel connection
First Claim
1. An endovascular prosthesis having a radially collapsed configuration and a radially expanded configuration comprising:
- a tubular body having a proximal end, a distal end, and a 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;
a mobile external coupling extending outwardly from the tubular body in the radially expanded configuration, 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 sealing cuff attached to the top of the mobile external coupling in the radially collapsed configuration and the radially expanded configuration, the sealing cuff extending from the top of the mobile external coupling towards the tubular body within the coupling lumen in the radially expanded configuration, wherein the sealing cuff is formed from a graft material and is generally cylindrically shaped.

Abstract
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.
