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 memory that stores a set of pre-established posture state definitions for delivery of posture state-responsive therapy to a patient, an external programmer comprising a user interface that receives a request from a user to update the set of pre-established posture state definitions, and a processor that updates the set of pre-established posture state definitions in response to the request.

First claim

The invention claimed is:

1. A method comprising:
storing a set of pre-established posture state definitions for delivery of posture state-responsive neurostimulation therapy to a patient, wherein the set of pre-established posture state definitions define one or more existing posture states;
receiving a posture state definition update request, from the patient via an external programmer, to update the set of pre-established posture state definitions to include a new posture state in addition to the one or more existing posture states, wherein receiving the posture state definition update request comprises receiving, from the patient via the external programmer when the patient assumes a position, an indication of the position as a boundary of the new posture state; and
updating, by at least one processor, the set of pre-established posture state definitions to include the new posture state in response to receiving the posture state definition update request.

2. The method of claim 1 , wherein updating the set of pre-established posture state definitions comprises defining, in response to the request for the new posture state.

3. The method of claim 2 , further comprising receiving, from the patient, a graphical representation of a location of the new posture state within a posture state space.

4. The method of claim 1 , wherein the position is a first position and the boundary is a first boundary, and wherein receiving the posture update definition request further comprises receiving, from the patient via the external programmer when the patient assumes a second position, an indication of the second position as a second boundary of the new posture state within a posture state space, wherein the first boundary and the second boundary at least partially define the new posture state within the posture state space.

5. The method of claim 1 , wherein one or more boundaries of the new posture state within a posture state space are at least one of predefined or defined by an algorithm.

6. The method of claim 1 , further comprising associating one or more therapy parameter values with the new posture state, wherein the one or more therapy parameter values were used to deliver the posture responsive therapy to the patient when the new posture state was defined.

7. The method of claim 1 , further comprising:
associating a set of therapy parameter values with the new posture state;
subsequently detecting the new posture state; and
delivering the posture responsive therapy to the patient according to the set of therapy parameter values associated with the new posture state in response to the detection.

8. The method of claim 1 , further comprising receiving a request to modify a definition of at least one existing posture state of the one or more existing posture states, the set of pre-established posture state definitions comprising the definition of the at least one existing posture state, and wherein updating the set of posture state definitions comprises modifying the definition of the at least one existing posture state in response to the request to modify the at least one existing posture state.

9. The method of claim 8 , wherein modifying the definition of the at least one existing posture state comprises at least one of modifying a location or a boundary of the at least one existing posture state within a posture state space.

10. The method of claim 1 , wherein the external programmer comprises a patient programmer configured to be primarily used by the patient, wherein the patient programmer is different from a clinician programmer configured to be primarily used by a clinician.

11. An external programmer comprising:
a user interface configured to receive a posture state definition update request from a patient to update a set of pre-established posture state definitions to include a new posture state for delivery of posture responsive neurostimulation therapy to the patient, wherein:
the set of pre-established posture state definitions define one or more existing posture states,
the new posture state is in addition to the one or more existing posture states, and
the user interface is configured to receive, from the patient when the patient assumes a position, an indication of the position as a boundary of the new posture state; and

a processor configured to update the set of pre-established posture state definitions to include the new posture state in response to receiving the posture state definition update request.

12. The external programmer of claim 11 , wherein the processor is configured to define, in response to the request for the new posture state, the new posture state.

13. The external programmer of claim 12 , wherein the user interface is configured to receive, from the patient, a graphical representation of a location of the new posture state within a posture state space.

14. The external programmer of claim 11 , wherein the position is a first position and the boundary is a first boundary, and wherein the user interface is configured to receive, from the patient when the patient assumes a second position, an indication of the second position as a second boundary of the new posture state within a posture state space, wherein the first boundary and the second boundary at least partially define the new posture state within the posture state space.

15. The external programmer of claim 11 , wherein one or more boundaries of the new posture state within a posture state space are at least one of predefined or defined by an algorithm.

16. The external programmer of claim 11 , wherein the processor is configured to associate one or more therapy parameter values with the new posture state, and
wherein the one or more therapy parameter values were used to deliver the posture responsive therapy to the patient when the new posture state was defined.

17. The external programmer of claim 11 , wherein the user interface is configured to receive a request to modify a definition of at least one existing posture state of the one or more existing posture states, the set of pre-established posture state definitions comprising the definition of the at least one existing posture state, and wherein the processor is configured to modify the definition of the at least one existing posture state in response to the request to modify the at least one existing posture state.

18. The external programmer of claim 17 , wherein the processor is configured to modify at least one of a location or a boundary of the at least one existing posture state within a posture state space.

19. A system comprising:
a memory configured to store a set of pre-established posture state definitions for delivery of posture state-responsive neurostimulation therapy to a patient, wherein the set of pre-established posture state definitions define one or more existing posture states;
an external programmer comprising a user interface configured to receive a posture state definition update request from the patient to update the set of pre-established posture state definitions to include a new posture state in addition to the one or more existing posture states, wherein the user interface is configured to receive, from the patient when the patient assumes a position, an indication of the position as a boundary of the new posture state; and
a processor configured to update the set of pre-established posture state definitions to include the new posture state in response to receiving the posture state definition update request.
