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

Abstract: A fixation device for use in securing a cranial bone flap with a cranial bone mass at the location of a burr hole. In one implementation the fixation device includes a closure plate having a substrate with an outer surface and an inner surface and with at least a portion of the inner surface adapted to be applied against the outer face of the outer edges of the cranial bone mass and the cranial bone flap at the location of the burr hole. The closure plate is also adapted with a burr hole fitting coupled to and spaced a distance below the inner surface of the substrate and adapted for being inserted entirely into the burr hole. The fitting may include one or more peripheral portions adapted for being pressed against the inner wall of the burr hole when the fitting is inserted therein. The peripheral portions are endowed with a freedom of movement that enables the fitting to be inserted into the burr hole.

Abstract: A fixation device for the fixation of bone fragments, applicable to the mutual fastening of bone fragments temporarily separated during a surgical operation or as a result of a trauma. The device is also suitable for the fixation of a bone flap in the replacement thereof in a corresponding aperture made in the cranium or cranial bone mass. The device is made of biocompatible material and comprises a flexible strip and fastening means, the strip having a length allowing the formation of a fastening loop tightly fastening the bone fragments to be joined together. The fastening means are provided with at least one opening provided with interlocking means allowing the passage of a free end of the strip and preventing its extraction in the direction opposite to the insertion.

Abstract: An apparatus for securing together first and second bone segments having peripheral surfaces comprising one or more bends. In some implementations the fixation device includes an elongate flexible strap having a proximal end and a distal end, the elongate flexible strap having a plurality of ratchet teeth disposed along an elongate distal portion thereof that function with a ratchet member within a locking head situated at the proximal end to permit the formation of a closed loop about the bone fragments. In some implementations the elongate flexible strap has a first elongate portion situated between the locking head and the elongate distal portion, the first elongate portion of the elongate flexible strap being more flexible than the elongate distal portion of the elongate flexible strap, the first elongate portion configured to extend across at least one of the one or more bends when the apparatus is in a secured state.
