A nuclear disc implant includes an inner fillable enclosure and an outer fillable enclosure. After insertion into a enucleated disc cavity, the inner enclosure is filled with a fluid and the outer fillable enclosure is filled with a curable material. The curable material is allowed to cure and the fluid is removed from the inner enclosure to leave an inner enclosure surrounded by an cured outer enclosure. A reinforcing band may be provided around the nuclear disc implant. An inflation tool to fill the nuclear disc implant is provided.
