Stent graft adaptor

摘要

A stent graft adaptor (10) has an outer graft tube (12) and an inner graft tube (14) with the inner graft (14) tube substantially concentric with and within the outer graft tube (12). A joining member (16) extends between the inner graft tube (14) and the outer graft tube (12). The joining member (16) can be a continuous fold of graft material extending from a proximal end of the outer tube (12) to a proximal end of the inner tube (14). The inner graft tube (14) has at least one self-expanding stent (24) on an outer surface thereof and the outer graft tube has at least one self-expanding stent (18) on an inner surface. The outer surface of the outer graft tube (12) provides a sealing surface to engage against the wall of a vessel and the inner tube (14) provides a sealing surface (26) to engage with a corresponding sealing surface of a stent graft deployed through it. The outer sealing surface can include barbs (22) to engage with the vasculature.
