Abstract

An implant for use in a spine includes a body and a plurality of structural members. The superior and inferior surfaces each include a ring and structural members arranged in a web-like pattern around the ring. Bone contacting members are arranged radially away from the ring and support members are arranged in a circumferential direction around the ring.

First claim

What is claimed is:

1. An implant, comprising:
a body including a ring, the ring further defining an opening;
the body defining a transverse plane dividing the implant into a superior half and an inferior half;
the ring defining a radial direction and a circumferential direction;
a outer member attached to the ring, wherein the outer member extends radially from the ring;
wherein the outer member has a generally helical geometry; and
wherein the ring further defines a central channel extending through the implant.

2. The implant according to claim 1 , wherein the central channel extends from a superior side to an inferior side of the implant.

3. The implant according to claim 1 , wherein the ring is located in a central region of the implant.

4. The implant according to claim 1 , wherein the body includes a peripheral frame portion that defines an outer periphery of the implant; and wherein the outer member extends from the ring to the peripheral frame portion.

5. The implant according to claim 1 , wherein the outer member is a first outer member, and wherein the implant further includes a second outer member having a generally helical geometry.

6. The implant according to claim 5 wherein the implant further includes a third outer member and a fourth outer member.

7. The implant according to claim 6 , wherein the first outer member and the second outer member extend from a first side of the ring to a first end of the implant, and wherein the third outer member and the fourth outer member extend from a second side of the ring to a second end of the implant.

8. The implant according to claim 7 , wherein the implant further includes a plurality of supports, wherein each of the plurality of supports are attached to at least one outer member, and wherein each of the plurality of supports extend in the circumferential direction.

9. The implant according to claim 8 , wherein the first outer member, the second outer member, the third outer member, the fourth outer member and the plurality of supports are arranged in a web-like pattern.

10. The implant according to claim 9 , wherein the web-like pattern is disposed in the superior half of the implant, and wherein the implant has another web-like pattern formed of outer members and supports disposed in the inferior half of the implant.

11. The implant according to claim 1 , further including a support attached to the outer member at an attachment region, wherein the support extends in the circumferential direction.

12. The implant according to claim 11 , wherein at the attachment region the support is disposed closer to the transverse plane than the outer member is to the transverse plane.

13. An implant, comprising:
a body;
the body defining a transverse plane dividing the implant into a superior half and an inferior half;
a first outer member attached to the body and disposed within the superior half of the implant;
a first support attached to the first outer member, the first support being disposed within the superior half of the implant;
a second outer member attached to the body and disposed within the inferior half of the implant;
a second support attached to the second outer member, the second support being disposed within the inferior half of the implant;
wherein an end of the first support is attached to an end of the second support; and
wherein the first outer member and the second outer member each have a generally helical geometry;
wherein the implant includes a first ring disposed in the superior half, wherein the first outer member is attached to the first ring;
the implant includes a second ring disposed in the inferior half, wherein the second outer member is attached to the second ring;
wherein the first ring and the second ring define a central channel extending through the implant.

14. The implant according to claim 13 , wherein the first ring is joined to the second ring by additional supports extending through the transverse plane, such that the first ring and the second ring define openings for the central channel extending through the implant.

15. The implant according to claim 13 , wherein the central channel extends from a superior side to an inferior side of the implant.

16. The implant according to claim 13 , wherein the first ring and the second ring are located in a central region of the implant.

17. An implant, comprising:
a body;
the body defining a transverse plane dividing the implant into a superior half and an inferior half;
a plurality of outer members disposed within the superior half of the implant and extending from a central region of the body to a periphery of the body; and
wherein each of the outer members in the plurality of outer members extend radially away from the central region of the body;
wherein each of the plurality of outer members have a generalized helical geometry; and
wherein the implant includes at least one ring disposed in the central region of the body and defining a central channel extending through the implant from a superior side to an inferior side of the body.

18. The implant according to claim 17 , wherein the implant includes three or more outer members.

19. The implant according to claim 17 , wherein the body includes a peripheral frame portion that defines an outer periphery of the implant; and
wherein the outer members extend from the at least one ring to the peripheral frame portion.

20. The implant according to claim 17 , wherein the implant further includes a plurality of supports, wherein each of the plurality of supports are attached to at least one outer member, and wherein each of the plurality of supports extend in a circumferential direction defined by the at least one ring.
