Abstract

In general, the disclosure relates to the delivery of therapy according to a detected posture state of a patient. The disclosure contemplates a variety of techniques for managing therapy delivered to a patient, including patient and clinician interaction with a medical device configured to deliver therapy according to posture state. In one example, the disclosure relates to a technique including delivering a first therapy to a patient via a medical device, the first therapy associated with a first posture state of the patient; receiving an indication from a user indicating that a second therapy should be delivered, the second therapy associated with a second posture state of the patient; and delivering the second therapy to the patient instead of the first therapy based on the indication.

Claims

1. A method comprising:

delivering a first therapy to a patient via a medical device while the patient occupies a first posture state, wherein the first therapy is defined for the first posture state of the patient;

determining the patient transitioned from the first posture state to a second posture state;

receiving a selection of a third posture state from a user via an external device while the patient occupies the second posture state, wherein a second therapy is defined for the third posture state of the patient; and

delivering, while the patient occupies the second posture state and not the third posture state, the second therapy to the patient based on the received selection, wherein at least one of the delivery of the first therapy, determination, receipt, and delivery of the second therapy are performed via one or more processors.

2. The method of claim 1, wherein delivering the second therapy to the patient comprises temporarily overriding delivery of a third therapy defined for the second posture state with delivery of the second therapy.

3. The method of claim 2, further comprising detecting an override termination action.

4. The method of claim 3, wherein the override termination action comprises at least one of expiration of a time period, detection of a patient posture state transition, or a patient input.

5. The method of claim 1, further comprising

delivering the first therapy to the patient while in the second posture state prior to receiving the selection from the user.

6. The method of claim 5, further comprising determining that the patient is in the first posture state, wherein delivering the first therapy to the patient comprises delivering the first therapy to the patient according to the determination that the patient is in the first posture state.

7. The method of claim 5, wherein the first posture state comprises a defined posture state and the second posture state comprises an undefined posture state.

8. The method of claim 1, further comprising delivering, prior to receiving the selection from the user, a third therapy to the patient based on the determination that the patient has transitioned to the second posture, wherein the third therapy is defined for the second posture state.

9. The method of claim 1, wherein the selection from the user selecting the third posture state is inputted with regard to a graphical representation of the third posture state presented via an user interface of the external device.

10. The method of claim 9, wherein the graphical representation of the third posture state comprises a textual representation of the third posture state.

11. A system comprising:

a therapy delivery module configured to deliver therapy to a patient; and

at least one processor configured to control the therapy module to deliver a first therapy to the patient, while the patient occupies a first posture state, wherein the first therapy is defined for the first posture state of the patient, determine the patient transitioned from the first posture state to a second posture state;

receive a selection of a third posture state from a user via an external device while the patient occupies the second posture state, wherein a second therapy is defined for the third posture state of the patient, and control the therapy module to deliver, while the patient occupies the second posture state and not the third posture state, the second therapy to the patient based on the received selection.

12. The system of claim 11, wherein the processor is configured to temporarily override delivery of a third therapy defined for the second posture state with delivery of the second therapy.

13. The system of claim 12, wherein the processor is further configured to detect an override termination action.

14. The system of claim 13, wherein the override termination action comprises at least one of expiration of a time period, a patient posture state transition, or a patient input.

15. The system of claim 11, wherein the processor controls the therapy module to deliver the first therapy to the patient while in the second posture state prior to receiving the selection from the user.

16. The system of claim 15, wherein the processor is further configured to determine that the patient is in the first posture state, wherein controlling the therapy module to deliver the first therapy to the patient includes controlling the therapy module to deliver the first therapy to the patent according to the determination that the patient is in the first posture state.

17. The system of claim 15, wherein the first posture state comprises a defined posture state and the second posture state comprises an undefined posture state.

18. The system of claim 11, further comprising a user interface configured to present a list of one or more posture states to the patient, the one or more posture states including the third posture state, and receive input from the user selecting the third posture state from the list.

19. The system of claim 11, further comprising a user interface configured to present an indicator indicating that an undefined posture state is detected based on detection of an undefined posture, and receive an input from the user indicating whether the user would like to select a defined posture state to define therapy delivered to the patient via the therapy delivery module.

20. The system of claim 11, wherein the processor controls the therapy module, prior to receiving the selection from the user, to deliver a third therapy to the patient based on the determination that the patient has transitioned to the second posture state, wherein the third therapy is defined for the second posture state.

21. The system of claim 11, wherein the selection from the user selecting the third posture state is inputted with regard to a graphical representation of the third posture state presented via a user interface of the external device.

22. The system of claim 21, wherein the graphical representation of the third posture state comprises a textual representation of the third posture state.

23. A system comprising:

means for delivering a first therapy to a patient via a medical device while the patient occupies a first posture state, wherein the first therapy is defined for the first posture state of the patient;

means for determining the patient transitioned from the first posture state to a second posture state;

means for receiving a selection of a third posture state from a user via an external device while the patient occupies the second posture state and not the third posture state, wherein a second therapy is defined for the third posture state of the patient; and

means for delivering, while the patient occupies the second posture state, the second therapy to the patient based on the received selection.

24. A non-transitory computer-readable storage medium comprising instructions for causing one or more processors to:

deliver a first therapy to a patient via a medical device while the patient occupies a first posture state, wherein the first therapy is defined for the first posture state of the patient;

determine the patient transitioned from the first posture state to a second posture state;

receive a selection of a third posture state from a user via an external device while the patient occupies the second posture state, wherein a second therapy is defined for the third posture state of the patient; and

control the therapy module to deliver, while the patient occupies the second posture state and not the third posture state, the second therapy to the patient based on the received selection.
