A spinal disc implant delivery device includes a blocking component having opposed distal and proximal ends. The proximal end of the blocking component includes an anchor member configured and adapted for movement between an undeployed position in which the anchor member can pass into and out of an opening in a disc annulus, and a deployed position in which the anchor member anchors the blocking component to the opening of the disc annulus. In the deployed position, the anchor member is configured to prevent extrusion of implant material from the opening of the disc annuls. An implant delivery needle is located radially within the blocking component and has opposed proximal and distal ends. The needle is configured to deliver implant material from the distal end thereof to an interior of a disc annulus.
