摘要：
A reinforcing and marker ring (60) for a stent graft is disclosed. The reinforcing and marker ring comprises a plurality of turns of a substantially inextensible resilient wire (71) in a circular shape and terminal ends (72, 78) at each end of the wire. The terminal ends each comprise a loop, each loop attachable to a stent graft (10) having an opening or a fenestration (24) so as to substantially lock a peripheral length of the circular shape. A marker winding (80) is wound helically around the reinforcing wire, the marker winding being viewable on an image display system employing electromagnetic radiation so as to indicate the location of a periphery of the fenestration. The circular shape of the resilient wire, with the marker winding wound around it, is collapsible under radial pressure to form a squashed circular shape for loading into a delivery device, the squashed circular shape self - expandable back to a substantially circular shape upon release from the delivery device.
