There is disclosed herein a self-expanding stent comprising a series of zig-zag stenting rings (A,B,C,D,E,F,D1,D2) connected by connecting links (12,14), the series including a sequence of three such rings A, B, C with the links (12) between any two axially adjacent rings A, B being circumferentially staggered relative to the links (14) between the other two axially adjacent rings B and C, characterized in that the points of infection (16,16',16",26,30,40) at one end of at least one of the rings (A,B,C,D,F) are staggered in their location along the longitudinal axis so as to approximate a wave function of longitudinal position around the circumference of the ring, and wherein each said one ring end formed as a waveform creates, as between itself and the end of any adjacent stenting ring (A,B,C,E,D2) to which it is connected, two or more eyelets (20) around the circumference of the stent between the adjacent stenting rings. |
