Abstract

A metal surgical implant has a first antenna wrapped around an elongated portion, the first antenna electrically coupled with circuitry, all tuned to a frequency below 450 kilohertz. The assembly is substantially sterile. A second antenna may also be wrapped around the elongated portion, also electrically coupled with the circuitry. The implant may be a hip implant.

Claims

1. A metal surgical implant assembly comprising:

a metal surgical implant with at least one elongated portion;

a first antenna wrapped around the at least one elongated portion;

the first antenna electrically coupled with circuitry;

the first antenna and circuitry tuned to a frequency below 450 kilohertz;

the assembly substantially sterile.

2. The assembly of claim 1 wherein the surgical implant comprises a hip implant.

3. The assembly of claim 1 wherein the surgical implant is stainless steel.

4. The assembly of claim 1 wherein the surgical implant is titanium.

5. The assembly of claim 1 further comprising a second antenna also wrapped around the at least one elongated portion;

the second antenna also electrically coupled with the circuitry;

the second antenna and circuitry tuned to a frequency below 450 kilohertz.

6. The assembly of claim 5 wherein the frequency to which the second antenna and circuitry is tuned is different from the frequency to which the first antenna and circuitry is tuned.

7. A metal tool comprising:

a metal tool with at least one elongated portion;

a first antenna wrapped around the at least one elongated portion;

the first antenna electrically coupled with circuitry;

the first antenna and circuitry tuned to a frequency below 450 kilohertz.

8. The assembly of claim 7 wherein the tool comprises a wrench.

9. The assembly of claim 7 wherein the tool is steel.

10. The assembly of claim 7 further comprising a second antenna also wrapped around the at least one elongated portion;

the second antenna also electrically coupled with the circuitry;

the second antenna and circuitry tuned to a frequency below 450 kilohertz.

11. The assembly of claim 10 wherein the frequency to which the second antenna and circuitry is tuned is different from the frequency to which the first antenna and circuitry is tuned.
