1. A ring for use in surgical operations, the ring corresponding to a ring design specifying, for each of a plurality of locations of the ring, a target width and a target height of the ring at the location, wherein the ring, when cut from a cylindrical medium, comprises an actual height and an actual width for at least a first location of the plurality of locations that differ from the target width and the target height at the first location such that an actual cross-sectional area of the ring at the first location is substantially similar to a target cross-sectional area of the ring, wherein the actual cross-sectional area of the ring at the first location is determined based on the actual height and actual width of the ring at the first location and wherein the target cross-sectional area of the ring at the first location is determined based on the target height and the target width of the ring at the first location.
