    摘要： Embodiments relate to a spinal nucleus implant with water absorption and swelling capabilities, compositions for producing the spinal nucleus implants, and methods of preparing and using the spinal nucleus implants. The spinal nucleus implant can be created from a composition comprising a mixture of non-hydrogel polymer material and at least one hydrophilic polymer, the weight ratio of non-hydrogel polymer material to the at least one hydrophilic polymer being from about 1:1 to about 19:1.

    摘要： Nucleus pulposus implants that are resistant to migration in and/or expulsion from an intervertebral disc space are provided. In one form of the invention, an implant includes a load bearing elastic body surrounded in the disc space by an anchoring, preferably resorbable, biocompatible material which may be in the form of an outer shell. In certain forms of the invention, the elastic body is surrounded by a supporting member, such as a band or jacket, and the supporting member is surrounded by the outer shell. Kits for forming such implants are also provided. In another form of the invention, an implant is provided that has locking features and optional shape memory characteristics. In yet another aspect of the invention, nucleus pulposus implants are provided that have shape memory characteristics and are configured to allow short-term manual, or other deformation without permanent deformation, cracks, tears, breakage or other damage. Methods of forming and implanting the implants are also described, as are delivery devices and components thereof for delivering the implants.
