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.
