1. A method of inserting a graft system to repair a vessel in need of repair comprising the steps of:
inserting a catheter from a vessel access location into a vessel to a deployment location in need of repair, the catheter having a graft system disposed thereon and not covered by a solid outer sheath, the graft system comprising:
a centrally disposed push wire surrounded by a graft;
a non-self-expandable stent disposed in at least part of the graft;
a strippable string extending circumferentially around at least part of the graft, the strippable string being removable to permit expansion of the graft and stent; and
a drawstring extending from the strippable string to the access location, wherein retraction of the drawstring results in the untying and removal of the string;
retracting the drawstring to cause untying and removal of the strippable string;
expanding the stent to anchor the stent and the graft within the vessel; and
removing the catheter.
