Abstract

The disclosure is directed towards posture-responsive therapy. To avoid interruptions in effective therapy, an implantable medical device may include a posture state module that detects the posture state of the patient and automatically adjusts therapy parameter values according to the detected posture state. A system may include a user interface that receives user input linking a plurality of posture states of a patient, and selecting a set of therapy parameter values for delivery of therapy to the patient for each of a linked posture states, a processor that defines the therapy to be delivered to the patient for each of the linked posture states based on the selection, and an implantable medical device that delivers the therapy to the patient for each of the linked posture states based on the selection.

First claim

The invention claimed is:

1. A method comprising:
selecting a plurality of posture states of a patient as linked posture states;
selecting a set of one or more therapy parameter values for delivery of therapy to the patient by an implantable medical device for all of the linked posture states, the set of one or more therapy parameter values being the same for all of the linked posture states;
associating, by at least one processor, the set of one or more therapy parameter values with all of the linked posture states based on the selection; and
defining the therapy to be delivered to the patient by the implantable medical device for all of the linked posture states based on the association.

2. The method of claim 1 , further comprising:
detecting one of the linked posture states; and
delivering therapy to the patient according to the therapy defined for the linked posture states in response to the detection.

3. The method of claim 1 , further comprising:
adjusting the selected set of therapy parameter values; and
automatically defining the therapy to be delivered to the patient for all of the linked posture states based on the adjusted set of therapy parameter values.

4. The method of claim 1 , wherein selecting the plurality of posture states of the patient as linked posture states comprises selecting, according to user input selecting the plurality of posture states from a list of posture states presented via a user interface, the posture states of the patient as the linked posture states.

5. The method of claim 1 , wherein selecting the plurality of posture states comprises selecting at least some of the posture states as the linked posture states automatically.

6. The method of claim 1 , wherein selecting the set of therapy parameter values comprises selecting one of a plurality of therapy program groups comprising one or more programs that include the set of therapy parameter values.

7. The method of claim 6 , wherein selecting the posture states comprises selecting the posture states as linked posture states for one of the therapy program groups.

8. The method of claim 6 , further comprising selecting the one of the therapy program groups for posture responsive therapy.

9. The method of claim 8 , further comprising selecting the linked posture states for posture responsive therapy.

10. The method of claim 8 , wherein posture responsive therapy comprises:
detecting a change from a first posture state to a second posture state; and
responsive to the detection, automatically changing from a first set of stimulation parameters associated with the first posture state to a second set of stimulation parameters associated with the second posture state; and
delivering therapy to the patient as defined by the second set of stimulation parameters.

11. The method of claim 6 , wherein selecting the posture states comprises selecting the posture states as linked posture states for a plurality of the therapy program groups.

12. The method of claim 6 , further comprising presenting a user interface that permits a user to link all of the posture states simultaneously.

13. The method of claim 1 , wherein the therapy comprises electrical stimulation therapy, the method further comprising delivering the electrical stimulation therapy via electrodes.

14. The method of claim 1 , further comprising at least one of enabling or disabling at least one therapy delivery feature based on the linking of the plurality of posture states of the patient.

15. The method of claim 1 , wherein the plurality of linked posture states of the patient is a subset of all posture states of the patient.

16. An external programmer for an implantable medical device, the programmer comprising:
a user interface configured to receive user input selecting a plurality of posture states of a patient as linked posture states, and select a set of one or more therapy parameter values for delivery of therapy to the patient by the implantable medical device for all of the linked posture states, the set of one or more therapy parameter values being the same for all of the linked posture states; and
a processor configured to associate the set of one or more therapy parameter values with all of the linked posture states based on the selection and define the therapy to be delivered to the patient by the implantable medical device for all of the linked posture states based on the association.

17. The programmer of claim 16 , wherein the processor is configured to program the implantable medical device to detect one of the linked posture states, and deliver therapy to the patient according to the therapy defined for the linked posture states in response to the detection.

18. The programmer of claim 16 , wherein the user interface is configured to receive user input adjusting the selected set of therapy parameter values, and the processor is configured to automatically define the therapy to be delivered to the patient for all of the linked posture states based on the adjusted set of therapy parameter values.

19. The programmer of claim 16 , wherein the processor is configured to select, according to user input selecting the plurality of posture states from a list of posture states presented via the user interface, at least some of the posture states as the linked posture states.

20. The programmer of claim 16 , wherein the selected set of therapy parameter values is defined by one of a plurality of therapy program groups comprising one or more programs that include the selected set of therapy parameter values.

21. The programmer of claim 20 , wherein the posture states are linked for one of the therapy program groups.

22. The programmer of claim 21 , wherein the user interface is configured to receive user input selecting the one of the therapy program groups for posture responsive therapy.

23. The programmer of claim 22 , wherein the linked posture states are selected for posture responsive therapy.

24. The programmer of claim 20 , wherein the posture states are linked for a plurality of the therapy program groups.

25. The programmer of claim 16 , wherein the user interface is configured to permit a user to link all of the posture states simultaneously.

26. The programmer of claim 16 , wherein the therapy comprises electrical stimulation therapy.

27. The programmer of claim 16 , wherein the processor is configured to at least one of enable or disable at least one therapy delivery feature based on the selecting of the plurality of posture states of the patient as linked posture states.

28. A system comprising:
a user interface configured to receive user input selecting a plurality of posture states of a patient as linked posture states, and select a set of one or more therapy parameter values for delivery of therapy to the patient for all of the linked posture states, the set of one or more therapy parameter values being the same for all of the linked posture states;
a processor configured to associate the set of one or more therapy parameter values with all of the linked posture states based on the selection and define the therapy to be delivered to the patient for all of the linked posture states based on the association; and
an implantable medical device configured to deliver the therapy to the patient for all of the linked posture states based on the association.
