First Claim
Patent Images
1. A method of performing a procedure on an intervertebral disc of a functional spine unit comprising:
- advancing at least a portion of a distal end of an implantation instrument into disc tissue,wherein said implantation instrument comprises a probe;
wherein said probe is releasably coupled to an implant;
wherein the implant is coupled to an anchor;
wherein said anchor is configured to penetrate a portion of a vertebral body adjacent the intervertebral disc;
retracting at least a portion of the implantation instrument such that at least a portion of the implant is placed between an anulus lamella and a portion of a nucleus of the intervertebral disc; and
implanting at least a portion of said anchor in the adjacent vertebral body.

7. A method of performing a procedure on an intervertebral disc of a functional spine unit comprising:
-
identifying an anulus of an intervertebral disc, wherein the anulus comprises a defect; advancing at least a portion of a distal end of a delivery device comprising a distal intradiscal component located at the distal end of said delivery device into a portion of the intervertebral disc; wherein the distal intradiscal component is releasably coupled to an implant comprising an anchor; wherein said anchor is configured to penetrate a portion of a vertebral body adjacent to the intervertebral disc; positioning at least a portion of said implant between the anulus and a portion of a nucleus of the intervertebral disc; and positioning at least a portion of said anchor the adjacent vertebral body. - View Dependent Claims (8, 9, 10, 11, 12)
