The present invention relates to a package-type artificial disc nucleus pulposus having an artificial disc nucleus pulposus and the retainer. Packaged artificial disc nucleus pulposus is provided with a hydrogel core to hydrate from the dehydrated state is formed. Further, the artificial disc nucleus pulposus is followed by transplantation into the nucleus pulposus cavity and is configured such that the hydrogel core is hydrated to a final hydrated state. The retainer is selectively embedded in the artificial disc nucleus pulposus. Further, at the time of contact of the hydrated core and, after retaining is configured to allow the hydrogel core to hydrate from the dehydrated state and prevent the hydrogel core to hydrate to a final hydrated state. Thus, the artificial disc nucleus pulposus is limited by the retainer portion in a hydrated state. In a preferred embodiment, an artificial disc nucleus pulposus / retainer combination is sealed to hydrous solution to hydrate the hydrogel core also in the outer shell, such as the internal pouch. In use, an artificial disc nucleus pulposus is removed from the retainer portion is implanted in the hydrated state.
