Regulating degradation of surgical implants
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.
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.
