Stent and method of manufacturing same

摘要

A stent including a substantially radially expandable scaffold including interlinked struts, the scaffold being configurable into both a retracted and an expanded configuration. In the retracted configuration, the diameter of the scaffold along at least a portion thereof is smaller than the diameter of the scaffold the expanded configuration. The stent further includes a sheath mounted to the scaffold so that at least some of the struts are embedded into the sheath. The sheath allows a substantially radial movement of the struts between the expanded and the retracted configurations with the at least some of the struts remaining embedded in the sheath during the substantially radial movement.
