Patent ID: 8353947

Claim:
A modular stent-graft system comprising: a self-expanding bifurcated female stent-graft component having a lumen therethrough comprising a trunk, a leg, and a stump shorter than said leg configured for receiving a male stent-graft; and a self-expanding male stent-graft component having a proximal end partially positioned within and locked with said lumen of said female stent-graft component; said proximal end having an eversed stent extension at the proximal end of said male stent-graft component, wherein the eversed stent extension is formed from stent members that form the male stent-graft component and is in the eversed configuration upon the male stent-graft component prior to deployment within said female stent-graft component to lock said male stent-graft component to an inner surface of said female stent-graft component with an outward force exerted by the self-expanding stent and the eversed stent extension attempting to return to a non-eversed configuration, said male stent-graft component having a covering attached thereto, and said eversed stent extension being uncovered, wherein the eversed stent extension contacts the covering in the eversed configuration.
