Abstract
Systems for minimally invasive disc augmentation include an anulus augmentation implant suited for minimally invasive deployment. A nucleus augmentation component may be included. The anulus augmentation implant shields weakened regions of the anulus fibrosus and/or resists escape of natural nucleus pulposus and/or the augmentation component. Methods and deployment devices are also disclosed. Several embodiments cause or allow fibrosus or bony ingrowth in or around the augmentation.
