Controlling the degradation of bioresorbable metal implants
View Patent ↗A degradation controlled metal implant and methods of controlling the degradation of the implant. In one embodiment, the implant includes a body, one or more apertures, and one or more fastener blanks fixed within one or more apertures. In another embodiment, the implant includes a body of a first material and a second material plated in various patterns over the first material.
1. An implant system comprising:
a plate consisting essentially of a first material and having a plurality of apertures;
a fastener configured to be disposed within at least one of the plurality of apertures and capable of securing the plate to a tissue; and
a fastener blank configured to be disposed within at least one aperture and to substantially fill the aperture without protruding from the plate, the fastener blank consisting essentially of a second material that is less noble than the first material.
2. The implant system of claim 1 , wherein the fastener blank comprises a screw head.
3. The implant system of claim 1 , wherein the first material and second material are metallic.
4. The implant system of claim 3 , wherein the tissue comprises bone.
5. The implant system of claim 1 , wherein the tissue comprises bone.
6. The implant system of claim 1 , wherein the fastener blank has a head that is press-fit into the apertures.
7. The implant system of claim 1 , wherein the fastener blank has a head that snaps into the apertures.
8. The implant system of claim 1 , wherein the fastener blank has a head with no shank.
9. The implant system of claim 1 , wherein the fastener blank is a wire.
10. The implant system of claim 1 , wherein the fastener blank has a threaded head threaded into the aperture.
11. The implant system of claim 1 , wherein the plate and the fastener do not include a coating layer.
12. The implant system of claim 1 , wherein the first metallic material is magnesium and the second metallic material is a magnesium alloy.
13. An implant system comprising:
a plate consisting of a first material and having a plurality of apertures;
a fastener configured to be disposed within at least one of the plurality of apertures and capable of securing the plate to a tissue; and
a fastener blank configured to be disposed within at least one aperture and to substantially fill the aperture without protruding from the plate, the fastener blank consisting of a second material that is less noble than the first material.
