Devices and methods for treating a damaged intervertebral disc to reduce or eliminate associated back pain. The present invention provides disc reinforcement therapy (DRT) which involves implanting one or more reinforcement members in and preferably around the annulus of the disc. The reinforcement members may be used to stabilize the annulus and/or compresses a portion of the annulus so as to reduce a bulge and/or close a fissure. The implantable devices and associated delivery tools may incorporate heating capabilities to thermally treat the annular tissue. Alternatively or in combination, other devices may be specifically employed for such thermal treatment.

What is claimed is: 1. A method of treating an intervertebral disc having an annulus and a nucleus, comprising: providing a first elongate member having a proximal end and a sharp tissue penetrating distal end; inserting the distal end of the first member into the annulus tissue, including piercing the annulus tissue with the sharp tissue penetrating distal end; providing a second elongate member having a proximal end and a distal portion configured to receive the first elongate member; positioning the distal receiving portion of the second member proximate the disc; passing the distal end of the first member through disc tissue; and receiving the first member in the distal receiving portion of the second member. 2. A method as in claim 1, wherein the distal receiving portion of the second member is inserted into the disc prior to receiving the first member. 3. A method as in claim 1, wherein the distal receiving portion receives a distal portion of the first member. 4. A method as in claim 1, wherein the distal receiving portion receives the distal end of the first member. 5.

A method as in claim 18, wherein the curved path is aligned with the receiving portion of the second member. 20. A method as in claim 1, wherein the first member enters the disc along a first path defined by the first member and exits the disc along a second path defined by the second member. 21. A method as in claim 1, wherein the first member enters and exits the disc along a path defined by the second member. 22. A method as in claim 1, wherein the first member comprises a stylet. 23. A method as in claim 1, wherein the first member comprises a hollow stylet. 24. A method as in claim 1, wherein the second member includes two lumens. 25. A method as in claim 1, wherein the first member is delivered via a hollow guide tube. 26. A method of treating an intervertebral disc having an annulus and a nucleus, comprising: providing a first elongate member having a proximal end, a curved distal portion defining a curvature, and a sharp tissue penetrating distal end; inserting the distal end of the first member into the annulus tissue, including piercing the annulus with the sharp tissue penetrating distal end; providing a second elongate member having a proximal end and a distal portion configured to receive the first elongate member; positioning the distal receiving portion of the second member proximate the disc in alignment with the curvature of the first member; passing the distal end of the first member through disc tissue along a curved path; and receiving the distal end of first member in the distal receiving portion of the second member. 27. A method as in claim 26, wherein the distal receiving portion of the second member is inserted into the disc prior to receiving the first member. 28. A method as in claim 26, wherein the receiving portion includes an opening sized to accommodate the first member. 29. A method as in claim 28, wherein the receiving portion includes a lumen sized to accommodate the first member. 30. A method as in claim 26, wherein the first member is advanced through the lumen of the second member. 31. A method as in claim 26, further comprising a flexible elongate line connected to a proximal portion of the first member. 32. A method as in claim 31, wherein the flexible elongate line comprises a suture. 33. A method as in claim 31, wherein the line passes through disc tissue. 34.
