A repair device ( 10 ) for affixing a migrating stent graft ( 30 ) to the interior surface of a vessel wall ( 31 ). The repair device includes tubular graft ( 11 ) with a bare or uncovered stent ( 16 ) affixed to the proximal end ( 12 ). The bare stent includes a plurality of distally pointed barbs ( 17 ) for securing the repair device to a vessel wall. A second stent ( 15 ) is positioned in the passage ( 14 ) of the tubular graft to expand the graft against the interior surface of the migrating stent graft ( 30 ). Proximally pointing barbs ( 20 ) are affixed to the struts of the second stent and extend through the graft material for securing the repair device to the migrating stent graft. Biological glue ( 22 ) and other sealing material ( 23 ) can be applied to the tubular graft and/or stents for sealing the repair device against the vessel wall and/or the interior of the migrating stent graft. |
