Claim:
1. A prosthesis for implantation within a body lumen, the prosthesis comprising: a tubular graft of a graft material; a stent comprised of a plurality of crowns and a plurality of struts with each crown being formed between a pair of opposing struts, the stent being coupled to the graft material proximate to an end of the tubular graft so as to have a first set of crowns adjacent to the end of the tubular graft and a second set of crowns distant from the end of the tubular graft relative to the first set of crowns; a pair of stoppers coupled adjacent to each crown of the first set of crowns, wherein each stopper has a tubular configuration and is attached to a respective one of the pair of opposing struts that the crown is formed between; and at least one stitch made adjacent to each end of each stopper, wherein the stitches abut against and contact an end face of each stopper in order to secure a longitudinal position of the graft material relative to each stopper and the strut it is attached to such that the first set of crowns are covered by and free of direct attachment to the graft material of the tubular graft.
