Abstract:
1. A stent system for use within a body lumen, the system comprising: an interior stent component having a proximal end, a distal end, and a generally tubular cylindrical body defining a central flow lumen there through; and an exterior stent component including a plurality of longitudinally-extending connectors, wherein the proximal and distal ends of the interior stent component are attached to the exterior stent component such that the longitudinally-extending connectors are radially positioned around the tubular body of the interior stent component, wherein when the stent system is in an expanded configuration the longitudinally-extending connectors of the exterior stent component bow radially outward away from the tubular body of the interior stent component to contact a vessel wall of the body lumen while the interior stent component remains radially centered within the longitudinally-extending connectors, and wherein foreshortening of the interior stent component reduces a length of the interior stent component between an unexpanded configuration and the expanded configuration of the stent system whereby proximal ends and distal ends of the longitudinally-extending connectors move closer together to bow the longitudinally-extending connectors radially outward.
