Abstract

An implant may include a first body member and a second body member, at least one bone contacting arched member, and a first external element extending from the first body member to the second body member, wherein the first external element has an undulating planar geometry in which the first external element undulates in a single plane.

Claims (35)

1. An implant, comprising:

a first body member and a second body member;

at least one bone contacting arched member extending between the first body member and the second body member; and

a first peripheral bone contacting element extending from the first body member to the second body member on a first lateral side of the implant;

a second peripheral bone contacting element extending from the first body member to the second body member on a second lateral side of the implant; and

a central bone contacting element that extends between the first peripheral bone contacting element and the second peripheral bone contacting element;

wherein the at least one bone contacting arched member bridges from the first body member to the central bone contacting element and bridges from the central bone contacting element to the second body member.

2. The implant according to claim 1 , wherein the central bone contacting element has an undulating planar geometry.

3. The implant according to claim 2 , wherein the central bone contacting element undulates in a substantially horizontal plane.

4. The implant according to claim 2 , wherein the central bone contacting element having an undulating planar geometry has a substantially rectangular cross-sectional shape.

5. The implant according to claim 1 , wherein the bone contacting arched member is a superior bone contacting element.

6. The implant according to claim 1 , wherein the first body member is located on an anterior side of the implant, and wherein the second body member is located on a posterior side of the implant.

7. The implant according to claim 1 , wherein a portion of the bone contacting arched member includes a portion that is aligned with a portion of the central bone contacting element.

8. The implant according to claim 7 , further including a second bone contacting arched member;

wherein a portion of the second bone contacting arched member is aligned with a portion of the central bone contacting element.

9. The implant according to claim 7 , wherein the bone contacting arched member is attached to the central bone contacting element in a region in which portions of the bone contacting arched member and the central bone contacting element are aligned.

10. The implant according to claim 1 , wherein the central bone contacting element, the first peripheral bone contacting element, and the second peripheral bone contacting element are all aligned in a common plane.

11. The implant according to claim 10 , wherein the central bone contacting element, the first peripheral bone contacting element, and the second peripheral bone contacting element are all aligned in a transverse plane of the implent.

12. An implant, comprising:

a first body member and a second body member;

at least one bone contacting arched member; and

an external element extending from the first body member to the second body member;

wherein the external element has an undulating planar geometry in which the external element undulates in a single plane;

wherein the external element forms a first peripheral bone contacting element extending from the first body member to the second body member on a first lateral side of the implant; and

wherein the at least one bone contacting arched member extends between the first body member and the second body member independently from the first external element.

13. The implant according to claim 12 , wherein the first external element having an undulating planar geometry has a circular cross-sectional shape.

14. The implant according to claim 12 , wherein the first external element having an undulating planar geometry has a substantially rectangular cross-sectional shape.

15. The implant according to claim 12 , wherein the bone contacting arched member is a superior bone contacting element.

16. The implant according to claim 12 , wherein the first body member is located on an anterior side of the implant, and wherein the second body member is located on a posterior side of the implant.

17. The implant according to claim 12 , wherein the implant includes a second external element extending from the first body member to the second body member; and

wherein the second external element is disposed on an opposite side of the implant from the first external element.

18. The implant according to claim 17 , further including a central bone contacting element extending from the first external element to the second external element.

19. The implant according to claim 18 , wherein the bone contacting arched member is attached to the central bone contacting element.

20. The implant according to claim 12 , wherein the bone contacting arched member is formed by a bone contacting element including a plurality of arched members;

wherein the plurality of arched members includes at least two arched members extending substantially parallel to and offset with respect to one another.
