An endovascular self-expanding stent system that can include a braid with a proximal end, a distal end, and a lumen formed therebetween. The braid can be formed from one or more wires woven to comprise interstices. A first expansion ring can be connected to the proximal end of the braid. A second expansion ring can be connected to the distal end of the braid. Each expansion ring can include a frame that imparts an outwardly expanding radial force to the braid. The frame can include a plurality of elongate members interconnected by one or more intersections.
