What is claimed is: 1. A method of intervertebral disc repair for treating a disc having an aperture, weakened, or thin portion in the wall of the annulus fibrosus of said intervertebral disc comprising: providing a fixation device having a first member connected to a second member; placing the first member of the fixation device into, or through, the wall of an annulus in a portion surrounding the aperture, or weakened or thin portion of the wall of said annulus; placing the second member of the fixation device in subannular space; and causing, or allowing, the first member of the fixation device to be drawn in tension to pull together, wholly or partially, the annular tissue surrounding said aperture, weakened, or thin portion of said annulus. 2. A method of claim 1, wherein said fixation device comprises at least one surgical suture. 3. A method of claim 2, wherein said surgical suture material is biodegradable. 4. A method of claim 1, wherein said fixation device comprises at least one anchor portion and at least one band portion. 5. A method of claim 1, wherein said fixation device is formed from biodegradable material or bioabsorbable material. 6. A method of claim 4, wherein said anchor portion comprises at least one T-anchor. 7. A method of claim 4, wherein said anchor portion comprises at least one barb. 8. A method of claim 7, wherein at least one tip of the at least one barb is formed from biodegradable material. 9. A method of claim 4, wherein said at least one band portion is formed from suture material. 10. A method of claim 4, wherein said at least one band portion is formed from at least one wire. 11. A method of claim 10, wherein said at least one wire comprises a nickel titanium alloy or stainless steel. 12. A method of claim 4, wherein a portion of said band that is contiguous with said anchor portion is formed from at least one wire, and a portion of said band spanning said aperture is formed from suture material. 13. A method of claim 12, wherein said suture material is in the form of a mesh tube. 14. A method of claim 12, wherein said suture material has a width greater than its height. 15. A method of claim 1, wherein said fixation device further comprises a knot. 16. A method of claim 15, wherein said knot is pre-formed prior to placement of said fixation device. 17. A method of claim 1, wherein said fixation device further comprises a locking device. 18. The method of claim 1, further including the step of rotating the second member in the subannular space prior to causing or allowing the first member to be drawn in tension. 19. The method of claim 1, wherein said fixation device comprises a biocompatible material.
