摘要 : A biodegradable metallic vascular stent includes: a base body which is tubular with a lumen along a longitudinal axis, wherein the base body has a plurality of circumferential support structures which are successively positioned along the longitudinal axis. The circumferential support structures are each composed of a sequence of repeat units and has two or more connectors, wherein two adjacent circumferential support structures are joined together by at least one of the connectors, and each of the connectors is attached to one of arched elements in the repeat units of the two adjacent circumferential support structures to be connected. The biodegradable metallic vascular stent possesses suited radial pressure, flexibility and fatigue strength. Furthermore, the stent is design for peripheral vascular disease and coronary artery disease treatment as well.
