  • Patent number: 8617247
    Abstract: An implant for an intervertebral space with a shaped body. The implant makes possible rotation of the implant about the longitudinal axis of the body in one direction and prevents such rotation in the opposite direction.
    Type: Grant

  • Patent number: 8133281
    Abstract: An intervertebral implant with a central axis, a top part, a bottom part, a joint comprising a joint part and a joint shell, and a joining means. The top part has a top apposed surface that is suitable for placing it on a vertebra situated above it; The bottom part has a bottom apposed surface, that is suitable for placing it on a vertebra situated below it. One of the two parts is operatively associated with a convex joint part and the other part to a matching joint shell. The joint part and the joint shell are mounted against one another in a sliding manner such that the top part and the bottom part can rotate relative to one another at least about one axis of rotation. The joining means holds the top part and the bottom part together without impairing the capability of the joint to pivot while allowing a clearance between the joint part and the joint shell.

  • Patent number: 8012208
    Abstract: An implant for an intervertebral space with a shaped body. The implant has a top contact surface to be placed on a base plate of a body of the vertebra adjoining the implant from above, a bottom contact surface to be placed on a cover plate of a body of the vertebra adjoining the implant from below, two lateral surfaces, a front lateral and a rear lateral surface as well as a central axis that intersects the two contact surfaces, a longitudinal axis that intersects the front and rear lateral surfaces and a transverse axis that intersects the lateral surfaces. The implant also has a central plane situated between the contact surfaces and at right angles to the central axis of the body. The contact surfaces have a plurality of macroscopic teeth with central axes, where the central axes of the plurality of teeth are inclined relative to the central plane in such a manner, that a rotation of the body of 90° about the longitudinal axis is facilitated in one direction and impeded in the other direction.

  • Patent number: 7704280
    Abstract: An intervertebral implant including a top part, a bottom part and a joint arranged axially between the top part and the bottom part. The top part includes a top surface suitable to be placed on the base plate of a body of the vertebra adjacent and above the site of removal. The bottom part has a bottom surface suitable to be placed on the cover plate of a body of the vertebra adjacent and below the site of removal. The joint includes a convex joint part with a first articular surface and a joint shell matching it, with a second articular surface mounted in a sliding manner on the first articular surface. The intervertebral implant including a temporarily locking mechanism to fix the two parts relative to one another.

  • Patent number: 7637956
    Abstract: An endoprosthesis for a joint, in particular a an intervertebral implant with a central axis, a top part, a bottom part and a joint provided between them, wherein the joint comprises at least two articular surfaces A and B that can slide on one another; the top part has a top apposed surface that intersects the central axis and lateral surfaces; the bottom part has a bottom apposed surface that intersects the central axis and lateral surfaces; and wherein the endoprosthesis comprises at least one channel suitable to convey body fluid, said channel terminating in one of the two articular surfaces A and B and connecting it with the exterior of the endoprosthesis for the joint.

  • Publication number: 20060229724
    Abstract: An intervertebral implant for restoring natural function to a spine following the removal or an intervertebral disk or part thereof. The implant comprises a central axis, a top part, a bottom part and a joint arranged axially between the top part and the bototm part. The top part comprises a top surface, a ventral side surface, a dorsal side surface and two lateral side surfaces, wherein the top surface is suitable to be placed on the base plate of a body of the vertebra adjacent and above the site of removal. The bottom part has a bottom surface, a ventral side surface, a dorsal side surface and two lateral side surfaces; wherein the bottom surface is suitable to be placed on the cover plate of a body of the vertebra adjacent and below the site of removal. The joint comprises a convex joint part with a first articular surface and a joint shell matching it, with a second articular surface mounted in a sliding manner on the first articular surface.
