Abstract

An intervertebral implant may include an anterior plate forming a first monolithic structure defining a first end of the implant, and including at least two screw holes each configured to receive a bone screw; and a plurality of coils extending from the anterior plate about a periphery of the implant. The screw holes may be angled such that, when the implant is inserted between two adjacent vertebrae, bone screws are guided into the adjacent vertebrae.

First claim

We claim:

1. An intervertebral implant comprising:
an anterior plate forming a first monolithic structure defining a first end of the implant, and including at least two screw holes each configured to receive a bone screw;
a plurality of coils extending from the anterior plate about a periphery of the implant; and
wherein the screw holes are angled such that, when the implant is inserted between two adjacent vertebrae, bone screws are guided into the adjacent vertebrae; and
wherein the implant includes a vertical opening extending completely through a center region of the implant through the plurality of coils.

2. The implant of claim 1 , wherein the plurality of coils includes multiple levels of coils stacked in a superior-inferior direction.

3. The implant of claim 2 , wherein the plurality of coils includes six levels of coils.

4. The implant of claim 1 , wherein the plurality of coils includes multiple coils concentrically arranged about a periphery of the implant.

5. The implant of claim 4 , wherein the plurality of coils includes three concentric coils.

6. The implant of claim 1 , wherein the plurality of coils includes sets of coils, each set including two congruent coils.

7. The implant of claim 6 , wherein the plurality of coils includes multiple levels of coils sets, each level including three sets of coils arranged concentrically about the periphery of the implant.

8. The implant of claim 1 , wherein the at least two screw holes includes:
a first screw hole angled superiorly and disposed on a first side of a vertically oriented center line of the anterior plate; and
a second screw hole angled inferiorly and disposed on a second side of the center line of the anterior plate.

9. The implant of claim 8 , wherein the first screw hole is angled slightly laterally away from the center line of the anterior plate; and
wherein the second screw hole is angled slightly laterally away from the center line of the anterior plate.

10. An intervertebral implant comprising:
an anterior plate forming a first monolithic structure defining a first end of the implant, and including at least two screw holes each configured to receive a bone screw;
a plurality of coils extending from the anterior plate about a periphery of the implant; and
wherein the plurality of coils includes multiple levels of coils stacked in a superior-inferior direction.

11. The implant of claim 10 , wherein the plurality of coils includes six levels of coils.

12. The implant of claim 11 , wherein each of the six levels of coils includes sets of coils, each set including two congruent coils.

13. The implant of claim 10 , wherein the plurality of coils includes multiple coils concentrically arranged about a periphery of the implant.

14. The implant of claim 13 , wherein the plurality of coils includes three concentric coils.

15. The implant of claim 10 , wherein the plurality of coils includes sets of coils, each set including two congruent coils.

16. The implant of claim 15 , wherein the plurality of coils includes multiple levels of coils sets, each level including three sets of coils arranged concentrically about the periphery of the implant.

17. The implant of claim 10 , wherein the at least two screw holes includes:
a first screw hole angled superiorly and disposed on a first side of a vertically oriented center line of the anterior plate; and
a second screw hole angled inferiorly and disposed on a second side of the center line of the anterior plate.

18. The implant of claim 17 , wherein the first screw hole is angled slightly laterally away from the center line of the anterior plate; and
wherein the second screw hole is angled slightly laterally away from the center line of the anterior plate.

19. The implant of claim 10 , wherein the implant includes a vertical opening extending completely through a center region of the implant through the plurality of coils.
