HERNIATED DISC REPAIR
Systems for minimally invasive disc augmentation include an anulus augmentation component and a nucleus augmentation component. Both are suited for minimally invasive deployment. The nucleus augmentation component restores disc height and/or replaces missing nucleus pulposus. The anulus augmentation component shields weakened regions of the anulus fibrosis and/or resists escape of natural nucleus pulposus and/or the augmentation component. Methods and deployment devices are also disclosed. Method of supporting and augmenting a nucleus pulposus by inserting a flexible biocompatible material into the disc space using an anchoring means are also provided.
1 . (canceled)
2 . An intervertebral disc system comprising:
an anulus augmentation device;
a nuclear augmentation material;
wherein the anulus augmentation device is configured to resist migration within a disc region bounded by the anulus and vertebral body endplates without depending on the nuclear augmentation material,
wherein the anulus augmentation device is independent of the nuclear augmentation material,
wherein the annulus augmentation device comprises a biocompatible support member, and
wherein said nuclear augmentation material comprises a fluid that remains fluid after said nuclear augmentation material is implanted or infused in an intervertebral disc; and
an anchor adapted to be coupled to the biocompatible support member.
3 . The system of claim 2 , wherein said anchor is a bone anchor.
4 . The system of claim 2 , wherein said biocompatible support member comprises a flexible patch.
5 . The system of claim 2 , wherein said biocompatible support member comprises a frame and a membrane.
