Abstract: Disclosed are tools and devices for use in repairing an intervertebral disc. The devices include an anchor configured to be secured in a vertebra adjacent the intervertebral disc and a prosthesis having an active part that is configured for placement inside the nucleus of the disc. The tools include an anchor placement tool that includes a chisel for carving the vertebra and a rotatable part that is used for engaging with and screwing the anchor into the vertebra. The tools also include a prosthesis placement tool that is configured to support and facilitate an attachment of the prosthesis to the anchor and to deploy the active part of the prosthesis in the nucleus of the disc. According to one embodiment the prosthesis placement tool is equipped with electronics for the purpose of verifying a corrected attachment of the prosthesis to the anchor. According to other embodiments, the electronics are included in a separate checker tool.

Abstract: A device (1, 100) for repairing an intervertebral disc comprising an anchoring body (2, 102), suitable for being advanced into and secured in one of the vertebrae adjacent the intervertebral disc; and a prosthesis (3, 103, 203, 303) attachable in a secure coupling position to the anchoring body (2, 102) and adapted for retaining or replacing the nucleus pulposus in an interior space of an outer annulus of the intervertebral disc, the anchoring body supporting and arranging in the cited coupling position the prosthesis such that the prosthesis is oriented to in a direction toward and through a hole in the outer annulus, the prosthesis comprising at least one active portion (4) adapted to assume and maintain a first placement shape (A) suitable for permitting the active portion to be inserted into and through the hole in the outer annulus during a placement thereof into the interior space of the outer annulus, and at least a second operative shape (B) suitable for at least partially occluding the hole in the ou
