Abstract
A spinal disk implant comprises a solid body having four faces arranged to define a right-rectangular solid body and two faces that define the ends of the solid body. The faces that define the right-rectangular body include two opposed side faces and two opposed transverse faces. The transverse faces have a central region with three-dimensional features thereon and an anterior platform region lying along an anterior margin of the transverse faces. The faces defining the ends of the solid body include a convexly curved anterior face and a posterior face. The solid body is made of a biocompatible synthetic material. A kit that may be used by a surgeon includes an implant and an implant delivery tool dimensioned to releasably hold the implant. The delivery tool preferably has a pair of flexible opposed arms extending from a base, separated so that the implant can fit between the arms, and may have a breakable release band extending around the implant to hold it in place until a weak link in the release band is intentionally broken during implantation.
