A self expanding stent ( 10 ) formed from a resilient wire. The resilient wire comprises a zig zag form including an odd number of struts ( 12 ) such as seven struts and a bend ( 14 ) between each strut. There is first loop ( 18 ) of the resilient wire at the terminal end of a first strut and a second loop ( 18 ) of the resilient wire at the terminal end of a last strut. The stent as formed is substantially planar but in use is formed into a substantially cylindrical form ( 20 ) by being stitched onto a tubular body of a biocompatible graft material with at least the first strut and the last strut overlapping. |
