Abstract

Medical devices coupled to a sensor, and systems including such devices, can generate data and analysis based on that data, which may be used to identify and/or address problems associated with the implanted medical device, including incorrect placement of the device, unanticipated degradation of the device, and undesired movement of the device. Also provided are medical devices coupled to a sensor, and devices and methods to address problems that have been identified with an implanted medical device.

First claim

What is claimed is:

1. A base station, comprising:
a housing; and
a base-station circuit disposed in the housing and configured:
to receive, from an implantable prosthesis, a plurality of signals, each signal representative of a movement of the implantable prosthesis at a different time;
to send the plurality of signals to a destination having a data-processing application configured to process each of the plurality of signals to provide a respective motion mode and to process the respective motion modes to determine a change in status of the implantable prosthesis; and
to receive a signal from a source, wherein the signal indicates the change in status of the implantable prosthesis.

2. The base station of claim 1 , wherein the base-station circuit is configured to poll the implantable prosthesis for the plurality of signals.

3. The base station of claim 1 , wherein the base-station circuit is configured to decrypt the plurality of signals before sending the plurality of signals to the destination.

4. The base station of claim 1 , wherein the base-station circuit is configured to encrypt the plurality of signals before sending the plurality of signals to the destination.

5. The base station of claim 1 , wherein the base-station circuit is configured to decode the plurality of signals before sending the plurality of signals to the destination.

6. The base station of claim 1 , wherein the base-station circuit is configured to encode the plurality of signals before sending the plurality of signals to the destination.

7. The base station of claim 1 , wherein the change in the status is indicative of a healing of the tissue surrounding the implantable prosthesis.

8. The base station of claim 1 , wherein the change in the status is indicative of an infection of the tissue surrounding the implantable prosthesis.

9. The base station of claim 1 , wherein the change in the status is indicative of a loosening of the implantable prosthesis within a bone.

10. The base station of claim 1 , wherein the change in status is indicative of wear of the implantable prosthesis.

11. The base station of claim 1 , wherein the change in status is indicative of malalignment of the implantable prosthesis.

12. The base station of claim 1 , wherein the change in status is indicative of a change in alignment of the implantable prosthesis.

13. The base station of claim 1 , wherein the data-processing application is configured to compare the respective motion modes to determine the change in status of the implantable prosthesis.

14. The base station of claim 1 , wherein each respective motion mode is a gait-frequency motion mode derived by filtering the respective signal to obtain a gait-frequency representation of the respective signal.

15. The base station of claim 14 , wherein the implantable prosthesis has a three-dimensional coordinate system, and each gait-frequency representation is based on an amplitude associated with each of the three dimensions of the coordinate system.

16. The base station of claim 1 , wherein each respective motion mode is a non-gait-frequency motion mode derived by filtering the respective signal to obtain a non-gait-frequency representation of the respective signal.

17. The base station of claim 16 , wherein the implantable prosthesis has a three-dimensional coordinate system, and each non-gait-frequency representation is based on an amplitude associated with each of the three dimensions of the coordinate system.

18. The base station of claim 1 , wherein each respective motion mode is a discontinuity motion mode based on a detection of a discontinuity in the respective signal.

19. The base station of claim 1 wherein the different times of the movement occur over a time period, wherein the total number of different times over the time period corresponds to a frequency that is related to a telemedicine code.

20. The base station of claim 1 wherein the different times of the movement occur over a time period, wherein the total number of different times over the time period corresponds to a frequency that allows a doctor to qualify for payment under a telemedicine insurance code.

21. The base station of claim 1 wherein the different times of the movement occur over a time period, wherein the total number of different times over the time period corresponds to a frequency that allows a doctor to qualify for full payment under a telemedicine insurance code.
