Abstract: A stent includes a tubular support structure extending from a distal end to a proximal end, the tubular support structure including an inner surface and an outer surface. A retractable anchor system is disposed relative to the tubular support structure and includes a frame member and a plurality of retractable anchors secured to the frame member. The plurality of retractable anchors are biased to a deployed configuration in which the plurality of retractable anchors extend radially outward from the outer surface of the tubular support structure but are radially inwardly compressible into a delivery configuration.
