Abstract

Claims (42)

1. An implant device for humans or mammals comprises:

a body structure having an exposed surface;

one or more portions of the exposed surface having a bone formation enhancing 3-dimensional pattern; the 3-dimensional pattern forms a continuous network having voids having a void to solid ratio mimicking the void to solid ratio of a pre-natal cancellous bone in a human or mammal and the pattern mimics a marine or sea mammal bone structure; and

wherein the bone pattern exhibits the following characteristics;

2. The implant device for humans or mammals of claim 1 wherein the exposed surface is on exterior portions of the body structure or internal portions of the body structure or both.

3. The implant device for humans or mammals of claim 2 wherein the one or more portions of the exposed portions having the bone formation enhancing 3-dimensional patterns are in the external exposed surfaces or in the internal exposed surfaces or both internal and external exposed surfaces.

4. The implant device for humans or mammals of claim 1 wherein the voids in the 3-dimensional pattern have a medium width of 30-300 microns.

5. The implant device for humans or mammals of claim 1 wherein at least 10 percent of said voids in the 3-dimensional pattern have a dimension of at least 3 microns.

6. The implant device for humans or mammals of claim 1 wherein the voids in the 3-dimensional pattern have a depth into the surface of 150 microns or less.

7. The implant device for humans or mammals of claim 1 wherein the body structure is made of an implantable plastic or polymer.

8. The implant device for humans or mammals of claim 7 wherein the plastic material can be any implantable grade material such as PEEK (polyether ether ketone), PEKK (polyether ketone ketone), polyethylene, ultra high molecular weight polyethylene, polyphenylsulfone, polysulfone, polythermide, acetal copolymer, polyester woven or solid or implantable grade lennite UHME-PE.

9. The implant device for humans or mammals of claim 1 wherein the body structure is made of a metal suitable for implanting in a human or mammal.

10. The implant device for humans or mammals of claim 9 wherein the metal is titanium or a titanium alloy.

11. The implant device for humans or mammals of claim 9 wherein the metal is stainless steel or a stainless steel alloy.

12. The implant device for humans or mammals of claim 7 wherein the plastic is PEEK.

13. The implant device for humans or mammals of claim 1 may include anchoring holes to secure the device to the skeletal structure with fasteners or alternatively can simply be held in place by and between adjacent skeletal structures.

14. The implant device for humans or mammals of claim 1 wherein the sea or marine mammal is a whale.

15. The implant device for humans or mammals of claim 1 wherein the sea or marine mammal is a dolphin.

16. The implant device for humans or mammals of claim 1 wherein the implant has the one or more portions having the bone formation 3-dimensional pattern exhibita stress neutral isotropic structure for enhancing bone formation.

17. The implant device for humans or mammals of claim 1 wherein the voids have a medium width of 500-800 microns in any open marrow regions of the implant device when formed as a trabecular bone structure.

18. The implant device for humans or mammals of claim 1 wherein the pattern also mimics the bone structure of a reduced low or zero gravity exposure or buoyant water supported marine mammal.
