providing a tubular member having a curved tip and a lumen extending therethrough; inserting the tip of the tubular member into the annulus; and
inserting the reinforcement member through the lumen of the tubular member and into the annulus.

6. A method as in claim 1, further comprising the steps of:
-
providing one or more implantable bias devices, each having a first vertebral attachment member, a second vertebral attachment member, and a bias force member applying a bias force therebetween while permitting near normal relative motion therebetween;
attaching the first attachment member of each implantable bias device to the first vertebra; and
attaching the second attachment member of each implantable bias device to the second vertebra.

7. A method as in claim 1, wherein the annulus has a peripheral curvature, and wherein the reinforcement member is implanted in a position substantially conforming to the curvature.
-
8. A method as in claim 1, wherein the annulus has a posterior portion with a posterior periphery, and wherein the reinforcement member is implanted in the posterior portion of the annulus in a position substantially aligned with the posterior periphery.
-
9. A method as in claim 1, wherein the reinforcement member applies a force to the annulus.
-
10. A method as in claim 9, wherein the force compresses a portion of the annulus.
-
11. A method as in claim 9, wherein the force is sufficient to deform the annulus.
