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. A method of treating an intervertebral disc comprising: identifying a herniated anulus segment protruding outward from a natural border of an intervertebral disc,wherein the herniated anulus segment comprises a defect;implanting a first anchor and a biocompatible support member in the interverteb
1. A method of treating an intervertebral disc comprising: identifying a herniated anulus segment protruding outward from a natural border of an intervertebral disc,wherein the herniated anulus segment comprises a defect;implanting a first anchor and a biocompatible support member in the intervertebral disc;positioning said first anchor such that at least a portion of said first anchor is in contact with an innermost surface of the anulus at a first location adjacent the defect in said anulus;positioning said biocompatible support member such that at least a portion of said biocompatible support member is in contact with the innermost surface of the anulus at a second location adjacent the defect in said anulus;connecting said first anchor and said biocompatible support member with a suture; andapplying tension and tightening said suture, thereby substantially closing said defect and maintaining the natural border of the intervertebral disc. 2. The method of claim 1, wherein said suture comprises woven material. 3. The method of claim 1, wherein said defect comprises a pre-existing hole in said anulus. 4. The method of claim 1, wherein said defect comprises an access hole formed in the herniated anulus segment. 5. The method of claim 1, wherein said suture is coupled with at least one of said first anchor and said biocompatible support member. 6. The method of claim 1, wherein said second location is spaced from the first location. 7. The method of claim 1, further comprising implanting one or more additional anchors in the disc. 8. The method of claim 1, wherein the biocompatible support member is an anchor. 9. The method of claim 1, wherein the first anchor and the biocompatible support member comprise metal. 10. A method of treating an intervertebral disc comprising: identifying a herniated anulus segment protruding outward from a natural border of an intervertebral disc,wherein the herniated anulus segment comprises a defect;providing a support member;providing a fixation device;positioning the support member such that at least a portion of said support member is in contact with an inner surface of an anulus lamella at a first location adjacent the defect in said anulus;positioning the fixation device in anulus tissue at a second location adjacent the defect;connecting the fixation device to the support member with a connection member; andapplying tension and tightening said connection member, thereby substantially closing said defect and constraining the herniated segment to the natural border of the intervertebral disc. 11. The method of claim 10, wherein said support member is a first anchor and wherein said fixation device is a second anchor. 12. The method of claim 10, wherein said support member is a barrier. 13. The method of claim 11, wherein said connection member is a suture. 14. The method of claim 13, wherein the suture comprises woven material. 15. The method of claim 11, wherein said first anchor and said second anchor comprise metal. 16. The method of claim 10, wherein positioning the fixation device in anulus tissue at a second location adjacent the defect comprises positioning the fixation device in contact with the inner surface of the anulus lamella. 17. The method of claim 10, wherein the fixation device and the support member are connected prior to positioning the support member and the fixation device. 18. The method of claim 10, wherein the defect comprises an access hole formed in the herniated anulus segment. 19. The method of claim 10, further comprising positioning a third anchor in contact with the inner surface of the anulus lamella at a third location adjacent the defect in said anulus. 20. The method of claim 19, further comprising positioning a fourth anchor in contact with the innermost surface of the anulus lamella at a fourth location adjacent the defect in said annulus, wherein the fourth location is spaced from the third location.
