摘要

The present invention relates to a device and method to perform 1) disc fusion, 2) artificial replacement of the nucleus, 3) artificial replacement of the annulus, or 4) artificial replacement of both the nucleus and annulus. The device is designed to be placed into the intervertebral space following discectomy. The invention includes a delivery catheter and an substantially fixed sized mesh loop with a lumen within the mesh loop and a center hole. The mesh loop partially self expands diametrically in diameter upon removal of the introducer sheath and can be further expanded by mechanical means.
