Abstract

A porous coating for a medical implant, wherein the porous coating comprises a porous, shape memory material.

Claims (28)

1. A method for providing therapy to a patient, the method comprising:

inserting a medical implant into a patient, wherein the medical implant comprises a dynamic porous material that comprises a porous structure formed of a shape memory alloy, wherein the porous structure comprises a honeycomb cellular structure that includes elements having a staggered orientation relative to other elements, wherein the dynamic porous material conforms to an adjacent bone to create an interference fit between the medical implant and the adjacent bone.

2. The method according to claim 1 wherein the porous structure comprises a regular repeating pattern.

3. The method according to claim 1 wherein the therapy provided by the outward force applied by the dynamic porous coating is bone remodeling.

4. The method according to claim 1 wherein the implant has a modulus between 1 and 20 GPa.

5. The method according to claim 1 wherein the porous structure comprises a dodecahedron cellular structure.

6. The method according to claim 1 wherein the implant comprises a singular structure.

7. The method according to claim 6 wherein the implant has a non-dynamic core and a dynamic surface.

8. The method according to claim 7 wherein the singular structure has a structural or material gradient.

9. The method according to claim 1 wherein the dynamic porous material is coated with a bone-promoting agent.

10. The method according to claim 1 wherein the dynamic porous material includes a first surface and a second surface that is different from the first surface.

11. The method according to claim 1 wherein the dynamic porous material has a gradient structure including stating regions and elastic regions.

12. The method according to claim 1 wherein the elements are hexagonal elements.

13. The medical implant comprising:

a dynamic porous material comprising a porous structure formed of a shape memory material, the medical implant being configured for insertion into a patient, wherein the porous structure comprises a honeycomb cellular structure that includes elements having a staggered orientation relative to other elements.

14. The implant according to claim 13 wherein the porous structure comprises a regular repeating pattern.

15. The implant according to claim 13 wherein the therapy provided by the outward force applied by the dynamic porous coating is bone remodeling.

16. The implant according to claim 13 where in the implant is a bone void filler.

17. The implant according to claim 13 wherein the implant is a bone augmentation device.

18. The implant according to claim 13 wherein the implant has a modulus between 1-20 GPa.

19. The implant according to claim 13 wherein the porous structure comprises a dodecahedron cellular structure.

20. The implant according to claim 13 wherein the implant comprises a singular structure.

21. The implant according to claim 20 wherein the implant has a non-dynamic core and a dynamic surface.

22. The implant according to claim 21 wherein the singular structure has a structural or material gradient.

23. The implant according to claim 13 wherein the dynamic porous material is coated with a bone-promoting agent.

24. The implant according to claim 13 wherein the dynamic porous material includes a first surface and a second surface that is different from the first surface.

25. The implant according to claim 13 wherein the dynamic porous material has a gradient structure including stating regions and elastic regions.

26. The implant according to claim 13 wherein the elements are hexagonal elements.
