Anchored anulus method
First Claim
1. A method of closing a defect in an anulus fibrosus of an intervertebral disc, comprising:
- inserting a barrier through an opening into a disc;
positioning said baiter relative to said defect, wherein said barrier obstructs passage of material from the interior of said disc into said defect;
inserting a straight fixation delivery apparatus operable to deliver a fixation means into said anulus on a first side of said defect,passing a first fixation means through said anulus and into said barrier;
inserting said straight fixation delivery apparatus into said anulus on a second side of said defect; and
passing a second fixation means through said anulus and into said barrier, thereby securing said barrier in two different locations to said anulus.

Abstract
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 nucleus augmentation component. Methods and deployment devices are also disclosed. Methods of repairing a herniated disc by displacing at least a portion of the herniated segment to within the pre-herniated borders of the disc and anchoring at least a portion of the displaced herniated segment to a site within the disc are also provided.
