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 annulus 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.
Claims18
A method of inserting a membrane into an intervertebral disc, comprising:
- providing a membrane on an insertion device;
- inserting the insertion device into the intervertebral disc along a first axis;
- and
- deploying the membrane laterally from the insertion device within the intervertebral disc between the nucleus pulposus and the annulus fibrosis along a second axis which is transverse to the first axis.
A method of inserting a membrane into an intervertebral disc, comprising:
- providing a membrane on an insertion device;
- inserting the insertion device into the intervertebral disc along a first axis, at a point located a distance away from a defect in the annulus fibrosis of the intervertebral disc and advancing the membrane across the defect;
- and
- deploying the membrane laterally from the insertion device within the intervertebral disc along a second axis which is transverse to the first axis.
