A containment structure for use with a workpiece vascular graft may include a sheath having two lateral edges； holes defined through the sheath in proximity to the lateral edges of the sheath, wherein longitudinally-adjacent holes are spaced longitudinally from one another； and a pull wire extending through the holes. A medical apparatus may include a vascular graft self-expandable from an insertion state to a deployed state； and a suture cuff located at one end of the vascular graft. A deployment tool may include a mandrel； a vascular graft placed about the mandrel, and a sheath wrapped about the vascular graft, wherein the sheath compresses the vascular graft to an insertion diameter. A hybrid graft may include a graft and a stent, where an end of the graft is affixed to an end of the stent.
