Patent ID: 8568482

Claim:
An implant kit, comprising: a height-adjustable implant for insertion between vertebral bodies, comprising: a first sleeve part having an outwardly facing surface with a bore formed thereon, the first sleeve part extending longitudinally from a proximal end to a distal end; a second sleeve part having a longitudinal portion with an external thread, the longitudinal portion at least partially lying in the first sleeve part so that the second sleeve part is prevented from rotating relative to the first sleeve part but is axially displaceable relative to the first sleeve part, the longitudinal portion of the second sleeve part having an inside surface bounding an internal cavity; a nut having a first toothed ring and an internal thread, the internal thread of the nut engaging with the external thread of the second sleeve part distal of the distal end of the first sleeve part; an end plate releasably fixed to an end face of the first sleeve part or the second sleeve part intended to be placed against a vertebral body, the end plate being secured to the end face; and a manipulating tool comprising: a rod extending into the bore on the outwardly facing surface of the first sleeve part and being removably fixed to the first sleeve part without passing through the internal cavity of the second sleeve part; and a second toothed ring rotatably encircling the rod and releasably engaging the first toothed ring so that rotation of the second toothed ring while the rod is fixed to the first sleeve part facilitates rotation of the nut.
