The present disclosure describes a system and method for forming a stent or stent-graft for use in the vasculature of a human patient. The system comprises a mandrel and a collar configured to slide and rotate in relation to the mandrel. The mandrel includes at least one groove that corresponds to the desired shape of a stent or stent-graft. The stent or stent-graft is formed by sliding and rotating the collar along the surface of the mandrel, which forces a wire to conform to the shape of the groove.
