A bioactive / biodegradable implant that repairs the degenerated disc is inflated in the nuclear space to repressurize the nuclear space in the intervertebral disc after the degenerated nucleus is removed. The The implant is filled with a high molecular weight fluid, gel or fluid and elastomer combination, preferably an unhydrated HA hydrogel / growth factor mixture with or without host cells. The graft is produced from a self-sealing valve that is placed between the discs and later allows one-way filling of the graft and a material that allows fiber growth, thereby stabilizing the graft Including. A variety of substances can be incorporated into the implant to promote healing, prevent transmission, or reduce pain. |
