Abstract
Methods and apparatuses for compressing and holding a bulging or herniated intervertebral disc. A number of fastener embodiments are disclosed, including a resiliently curved fastener, suture, screw, staple, tack and others. The curved fastener is resiliently straightened and loaded into a needle for delivery and deployment. In the intervertebral disc, the deployed fastener resumes the curvature to grip and hold the bulge. Alternatively, the suture is anchored and used to tie down the bulging tissue. The screw, staple or tack can also be used to securely fasten, compress and hold the bulge from impinging upon adjacent nerves or tissues.
