Abstract

ABSTRACT 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.
