Abstract
A single-set anti-extrusion ring has a plurality of ring segments with a mating face on each end. Each mating face has a 3-dimensionally curved topology and the first mating face is a mirror image of the second mating face so the ring segments fit together to form and anti-extrusion ring without gaps in an unexpanded condition, and no straight path through the anti-extrusion ring in an expanded condition.
