Abstract
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.
