Abstract

The present invention provides methods and devices for annulus disc repair with and without the use of a patch or stent. The methods and devices are particularly suited to the repair and/or reconstruction of the spinal disc wall (annulus) after surgical invasion or pathologic rupture, with reduced failure rate as compared to conventional surgical procedures.
