  • providing a self-expanding stent-graft in a folded configuration and maintained in said folded configuration by a removable, longitudinally positioned slip line attached along a longitudinal fold edge, said graft comprising a collagen material;

    introducing said folded self-expanding stent-graft to a selected site in a lumen; and
