Abstract
Instruments and methods are provided for implanting nucleus replacement material in an intervertebral disc nucleus space employing an inserter having proximal and distal end regions and a passageway effective for passing the material therethrough. The distal end region of the inserter includes a conical-shaped outer surface, and the passageway exits through a side surface of the inserter in the distal end region at other than the apex of the conical-shaped outer surface. The nucleus replacement material passing through the inserter exits into an intervertebral disc nucleus space when the passageway exit in the side surface at the distal end region is disposed in the nucleus space. The instrument may also include a cover locking mechanism having pivotally connected first and second cover plates with a latching tab and landing sized and configured to mate and lock the cover plates automatically when the inserter assumes an implanting configuration.
