A bioactive/biodegradable nucleus implant for repairing degenerated intervertebral discs that is inflated inside the nucleus space after the degenerated nucleus has been removed to re-pressurize the nuclear space within the intervertebral disc. The implant is inflated with a high molecular weight fluid, gel or combination of fluid and elastomer, preferably an under-hydrated HA hydrogel/growth factor mixture with or without host cells. The implant includes an internal, integral, self-sealing valve that allows one-way filling of the implant after it is placed within the disc, and is made from a material that allows fibrous in growth thereby stabilizing the implant. A variety of substances can be incorporated into the implant to promote healing, prevent infection, or arrest pain.
A stent for facilitating regeneration of an intervertebral nucleus, said intervertebral nucleus bounded at its upper and lower extremities by opposing vertebral endplates of adjacent vertebrae, and at its periphery by annulus fibrosus, comprising:
A method for facilitating regeneration of the intervertebral disc, the intervertebral disc having a region of nucleus pulposus tissue surrounded by annulus fibrosus, the intervertebral disc disposed between vertebral endplates of adjacent vertebrae, comprising:
A method for treating an intervertebral disc, the intervertebral disc having a region of nucleus pulposus tissue surrounded by annulus fibrosus, the intervertebral disc disposed between vertebral endplates of adjacent vertebrae, comprising:
