Stent Graft Repair Device
First Claim
1. A stent graft repair device comprising:
- a tubular graft having a proximal end, a distal end, and a passage extending longitudinally therethrough, a second expandable stent disposed on an interior surface and in the passage of the tubular graft, and a first expandable stent attached to at least one of the distal and the proximal ends of the tubular graft and extending longitudinally therefrom and from the passage, the first expandable stent having a first plurality of barbs attached thereto and extending longitudinally therealong and pointing in a first direction toward the other end of the at least one of the distal and the proximal ends of the tubular graft.

Abstract
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.
