A stent comprising at least one individual closed hoop member 1 formed from a resilient material, the hoop 1 having a diametral dimension in a substantially circular configuration that exceeds the diameter of the largest blood vessel into which it will be inserted; and the hoop being resiliently deformable so as to occupy a spatial envelope of reduced diameter for insertion into a lumen, wherein when occupying a spatial envelope of reduced diameter for insertion into a lumen, the closed hoop member 1 has at least two substantially diametrically-opposed generally circumferentially extending regions 2; and at least two regions 3 that extend at least in part generally axially relative to the generally circumferentially extending regions 2, each of said regions 3 that extend at least in part generally axially being disposed between two of said generally circumferentially extending regions 2. |
