Implant for intervertebral space
First Claim
1. An implant for an intervertebral space formed between cover plates of adjoining vertebrae, said implant comprising essentially a cuboid-shaped body having a device for gripping a tool wherein said device is adapted to allow for the application of a rotational force on said implant in either rotational direction around a longitudinal axis through said implant and for removable insertion of said tool and further wherein said body comprises a plurality of openings for filling with graft material, said plurality of openings being arranged such that when filled with graft material, said graft material contacts the cover plates when said implant is in position in the intervertebral space.

33. An implant for an intervertebral space formed between cover plates of adjoining vertebrae, said implant comprising essentially a cuboid-shaped body having a substantially rectangular cross section with two rounded sides across a diagonal of the rectangle, posterior and anterior ends wherein the posterior end of the implant is designed such that a second implant can be connected anteriorly to the implant by a connector, and a device for gripping a tool wherein said device is adapted to allow for the application of a rotational force on said implant in either direction around a longitudinal axis through said implant and further wherein said body comprises a plurality of openings for filling with graft material, said plurality of openings being arranged such that when filled with graft material, said graft material contacts the cover plates when said implant is in position in the intervertebral space.

34. An implant for an intervertebral space formed between cover plates of adjoining vertebrae, said implant being designed such that it can be interlocked with a second implant either prior to being implanted or while in situ, and said implant comprising essentially a cuboid-shaped body having a substantially rectangular cross section with two rounded sides across a diagonal of the rectangle, and a device for gripping a tool wherein said device is adapted to allow for the application of a rotational force on said implant in either direction around a longitudinal axis through said implant and further wherein said body comprises a plurality of openings for filling with graft material, said plurality of openings being arranged such that when filled with graft material, said graft material contacts the cover plates when said implant is in position in the intervertebral space.
- 35. An implant for insertion and rotational locking in an intervertebral space formed between cover plates of adjoining vertebrae, said implant comprising a generally cuboid-shaped body having major, minor and median length axes of differing dimensions, said body having external surfaces intersecting said axes, a device for coupling with a tool, said device being located adjoining one of said surfaces of said body intersecting said major axis, wherein said device is adapted to allow for the application of a rotational force on said implant in either rotational direction around said major axis through said implant and for uncoupling of said tool, and at least one opening located in each of said surfaces intersecting said median axis.
