Abstract
Abstract Devices for implantation into an intervertebral disc can include a membrane support member to augment a disc having a defect. A defect in the anulus of a disc can be repaired using a prosthesis such as a barrier. The barrier can include a sealant and an enlarger. The barrier can be implanted into the disc using a delivery cannula, an advancer and at least one control filament to control the positioning of the barrier. A stiffening element can be included within the barrier to impart stiffness to the barrier. The support member can also be connected to an anchor.
