Abstract
A stent for a stent-graft includes: a first ring; a second ring; and spring elements coupling the first ring to the second ring, wherein the first ring, the second ring and the spring elements are integral. During maneuvering of the stent-graft through the tortuous human anatomy, the first ring is bent or flexed relative to the second ring. However, the spring elements are distorted to accommodate this bending. Further, since the stent is integral, a graft material only has to be sewn to the second ring minimizing the delivery profile of the stent-graft.
