A device is disclosed that includes a bone stent positioned within a bony access channel formed within a vertebra. The bony access channel may extends from an outer end of the vertebra through an endplate. The device includes an end cap attached to a proximal end portion of the bone stent and is configured to, post-operatively, open to allow a reintroduction of a material to a spinal intradiscal space or intervertebral disc and to seal access to the spinal intradiscal space or the intervertebral disc after the reintroduction of the material.
