Abstract
This invention provides a method and graft system for aneurysm repair comprising a prosthetic graft with means to draw a distal extremity of the graft over a portion of an expandable anchoring member. Prior to deployment, the graft and the anchoring member do not overlap to reduce the outer diameter of the delivery system. Preferably, the drawing means comprises pull strands connected to the distal extremity of the graft so that the distal extremity of the graft may be pulled over a proximal portion of the anchoring member. Subsequent expansion of the anchoring member seals the overlapped graft against the vessel wall to minimize blood flow-by and secures the graft in the vessel. Securing means may be advanced up each pull strand to abut the anchoring member and further secure the graft to the anchoring member. The graft may also comprise means to guide a second expandable anchoring member to the proximal end of the graft. Preferably, the guiding means comprise guide strands connected to a proximal extremity of the graft. The anchoring member can then be advanced up the guide strands until the graft overlaps the second anchoring member. Expansion of the second anchoring member secures the proximal end of the graft.
