Abstract

A scaffolded stent-graft includes a graft material comprising an inner surface and an outer surface. The inner surface defines a lumen within the graft material. The scaffolded stent-graft further includes a scaffold comprising a mesh coupled to the graft material at the outer surface. The scaffold is configured to promote tissue ingrowth therein. In this manner, the scaffold enhances tissue integration into the scaffolded stent-graft. The tissue integration enhances biological fixation of the scaffolded stent-graft in vessels minimizing the possibility of endoleaks and migration.
