Abstract
Described are various embodiments of an improved endoprosthesis that includes a generally tubular graft, a plurality of independent stent hoops connected to the graft and at least one suture. The at least one suture connects one apex of one stent hoop to two apices of another stent hoop to reduce a predetermined distance between distinct stent hoops so that in a released configuration in a body vessel, the stent-graft is curved away from the longitudinal axis to conform to the body vessel and reduce formation of a gap between one end of the stent-graft with an inner surface of the body vessel.
