Devices for delivering spinal disc implants

A spinal disc implant delivery device comprising:

• a) a blocking component having opposed distal and proximal ends, the distal end of the blocking component including 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, wherein in the deployed position, the anchor member is configured to prevent extrusion of implant material from the opening of the disc annulus, wherein the anchor member is further configured and adapted for movement from the undeployed position to the deployed position by advancing the anchor member toward the disk annulus;
• and
• b) an implant delivery needle located radially within the blocking component and having opposed proximal and distal ends, the needle being configured to deliver implant material from the distal end thereof to an interior of the disc annulus,
• wherein the anchor member includes a membrane lining the mesh portion to prevent extrusion of implant material through the mesh portion.
