Abstract

Embodiments of an implant that is configured with materials to prevent degradation or corrosion. The implant can comprise an elongate body and a degradation-delaying element disposed thereon, where the degradation-delaying element can be configured to reduce or retard corrosion of the elongate body.

First claim

What is claimed is:

1. An implant, comprising:
a body having a proximal end and a distal end, the distal end forming a tip with a cutting edge;
a suture retaining member having a first part and a second part, the first part forming an aperture set apart from the proximal end and the second part extending into the body; and
a coating disposed on the suture retaining member to slow a rate of corrosion of the first part relative a rate of corrosion of the body,
wherein the coating forms a first area on the suture retaining member and a second area on the body, each of the first area and the second area of different thickness.

2. The implant of claim 1 , wherein the second part is wholly surrounded by the first part.

3. The implant of claim 1 , wherein the first part and the second part comprise a single, unitary structure.

4. The implant of claim 1 , wherein the second part comprises Mg-alloy.

5. The implant of claim 1 , wherein the body comprises a polymer.

6. The implant of claim 1 , wherein the body comprises a polymer and the second part comprises MG-alloy.

7. The implant of claim 1 , wherein the body comprises threads disposed between the proximal end and the tip with the cutting edge.

8. The implant of claim 1 , wherein the second part extends from the proximal end to the distal end.

9. An implant, comprising:
a body having a proximal end and a distal end, the distal end forming a tip with a cutting edge;
a suture retaining member having a first part and a second part, the first part forming an aperture set apart from the proximal end and the second part extending into the body; and
a coating disposed on the suture retaining member to slow a rate of corrosion of the first part relative a rate of corrosion of the body,
wherein the coating forms a first area on the suture retaining member and a second area on the body, the second area varying in thickness between the proximal end and the distal end of the body.

10. The implant of claim 9 , wherein the second part is wholly surrounded by the first part.

11. The implant of claim 9 , wherein the first part and the second part comprise a single, unitary structure.

12. The implant of claim 9 , wherein the second part comprises Mg-alloy.

13. The implant of claim 9 , wherein the body comprises a polymer.

14. The implant of claim 9 , wherein the body comprises a polymer and the second part comprises MG-alloy.

15. The implant of claim 9 , wherein the body comprises threads disposed between the proximal end and the tip with the cutting edge.

16. The implant of claim 9 , wherein the second part extends from the proximal end to the distal end.

17. An implant, comprising:
a body having a proximal end and a distal end, the distal end forming a tip with a cutting edge;
a suture retaining member having a first part and a second part, the first part forming an aperture set apart from the proximal end and the second part extending into the body; and
a coating disposed on the suture retaining member to slow a rate of corrosion of the first part relative a rate of corrosion of the body,
wherein the coating forms a first area on the first part and a second area on the body, the second area reducing in thickness from the proximal end to the distal end.

18. The implant of claim 17 , wherein the second part is wholly surrounded by the first part.

19. The implant of claim 17 , wherein the first part and the second part comprise a single, unitary structure.

20. The implant of claim 17 , wherein the body comprises threads disposed between the proximal end and the tip with the cutting edge.
