Abstract

Apparatus, system, and method are disclosed herein for controlling movement of an orthopedic joint prosthesis in a mammalian subject. The apparatus, system, or method includes an orthopedic brace configured to control movement of an orthopedic joint prosthesis. The apparatus, system, or method includes one or more sensors and one or more controllers in communication with the one or more sensors. The one or more sensors are configured to be remote from the orthopedic joint prosthesis, wherein the one or more sensors in communication with the one or more controllers are configured to detect and control one or more alignment orientations of the orthopedic joint prosthesis.

Claims

1. An apparatus comprising:

an orthopedic brace adapted to be external to and adapted to contact a subject'"'"'s body and including a first member and a second member, wherein the first member is configured to control movement of a first component of an internal orthopedic joint prosthesis relative to the second member and the second member is configured to control movement of a second component of the internal orthopedic joint prosthesis;

one or more sensors remote from the internal orthopedic joint prosthesis, wherein at least one of the one or more sensors are configured to detect one or more alignment orientations of the first component relative to the second component of the internal orthopedic joint prosthesis, the at least one of the one or more sensors configured to transcutaneously detect at least one portion of at least one of the first component and the second component of the internal orthopedic joint prosthesis;

one or more controllers in communication with the one or more sensors and operably connected with one or more actuators of the orthopedic brace, and wherein the actuators are configured to adjust the one or more alignment orientations of the internal orthopedic joint prosthesis.

2. The apparatus of claim 1, wherein the controller permits unrestrained motion of the internal orthopedic joint prosthesis under a first set of alignment orientations, and restrained motion of the orthopedic joint prosthesis under a second set of alignment orientations.

3. The apparatus of claim 2, wherein the second set of alignment orientations include separation of the first component relative to the second component of the orthopedic joint prosthesis.

4. The apparatus of claim 2, wherein the restrained motion further includes a motion from the second set of alignment orientations towards the first set of alignment orientations.

5. The apparatus of claim 2, wherein the restrained motion further includes a reduction of one or more alignment differences between the second set of alignment orientations and the first set of alignment orientations.

6. The apparatus of claim 1, wherein the controller permits unrestrained motion of the internal orthopedic joint prosthesis under a first set of alignment orientations, and stops motion of the orthopedic joint prosthesis under a second set of alignment orientations.

7. The apparatus of claim 1, wherein the one or more actuators are configured to control movement of the first member relative to the second member of the orthopedic brace, in response to the one or more controllers.

8. The apparatus of claim 7, wherein the one or more controllers are configured to control application of force to the internal orthopedic joint prosthesis by the one or more actuators of the orthopedic brace.

9. The apparatus of claim 7, wherein the one or more actuators are configured to exert force on the first component relative to the second component of the internal orthopedic joint prosthesis.

10. The apparatus of claim 9, wherein the one or more actuators are configured to exert linear force or rotational force on the orthopedic joint prosthesis.

11. The apparatus of claim 1, wherein the one or more sensors are configured to be located within the orthopedic brace.

12. The apparatus of claim 1, wherein the one or more sensors are configured to determine a separation between the first component and the second component of the internal orthopedic joint prosthesis.

13. The apparatus of claim 1, wherein the one or more sensors are configured to determine a movement between the first component and the second component of the internal orthopedic joint prosthesis.

14. The apparatus of claim 1, wherein the one or more sensors are configured to detect one or more of angle, motion, flexion, extension, position, speed, or acceleration of the internal orthopedic joint prosthesis.

15. The apparatus of claim 1, further including a power source.

16. The apparatus of claim 1, further including the one or more controllers configured to use information from a model of one or more of a limb or a joint of the mammalian subject, wherein the one or more controllers are configured to predict future actions or consequences of movement of the orthopedic brace.

17. The apparatus of claim 1, wherein the one or more actuators include a damper mechanism.

19. The system of claim 14, wherein the controller permits unrestrained motion of the orthopedic joint prosthesis under a first set of alignment orientations, and restrained motion of the orthopedic joint prosthesis under a second set of alignment orientations.

18. A system comprising:

an orthopedic brace adapted to be external to and adapted to contact a subject'"'"'s body and including a first member and a second member, wherein the first member is configured to control movement of a first component of an internal orthopedic joint prosthesis relative to the second member which is configured to control movement of a second component of the internal orthopedic joint one or more sensors remote from the internal orthopedic joint prosthesis, wherein the one or more sensors are configured to detect one or more alignment orientations of the first component relative to the second component of the internal orthopedic joint prosthesis, the one or more sensors configured to transcutaneously detect at least one portion of at least one of the first component and the second component of the internal orthopedic joint prosthesis;

one or more controllers in communication with the one or more sensors, and operably connected with one or more actuators of the orthopedic brace, and wherein the one or more actuators of the orthopedic brace are configured to adjust the internal orthopedic joint prosthesis.

20. The system of claim 18, wherein the one or more actuators include a damper mechanism.

21. An apparatus comprising:

an orthopedic brace adapted to be external to and adapted to contact a subject'"'"'s body and including a first member and a second member, wherein the first member is configured to control movement of a first component of an internal orthopedic joint prosthesis and the second member is configured to control movement of a second component of the internal orthopedic joint prosthesis;

one or more sensors remote from the internal orthopedic joint prosthesis, wherein the one or more sensors are configured to detect one or more alignment orientations of the first component relative to the second component of the internal orthopedic joint prosthesis, the one or more sensors configured to transcutaneously detect at least one portion of at least one of the first component and the second component of the internal orthopedic joint prosthesis, wherein alignment orientations includes at least one of a change in distance or angle between the first component and the second component;

one or more controllers in communication with the one or more sensors and operably connected with one or more actuators of the orthopedic brace, and wherein the actuators are configured to adjust the one or more alignment orientations of the internal orthopedic joint prosthesis.
