ABSTRACT:
A system for repairing a vertebral disc defect, such as hernia or bulge, a full or partial tear in the annulus, or a weakened annulus wall as a result of an excision procedure. The system introduces a treatment device arranged to repair the defect, and may prevent the leakage of fluid from the nucleus. The components of the device may be resorbable materials, and may induce the ingrowth of cellular material into the components. The system may feature a locating device to ensure proper placement of the treatment device.
