Abstract

An implantable medical device delivers neurostimulation therapy to a patient according to a parameter set. A parameter set may consist of a number of programs that are delivered substantially simultaneously. When programming the implantable medical device for the patient, a clinician programmer may maintain a session log for the patient that includes a listing of programs delivered to the patient and rating information provided by a clinician and the patient for programs of the list. The listing may be ordered according to the rating information in order to facilitate the selection of programs for a parameter set. A program library that may include particularly effective programs organized according to a directory structure may be stored in a memory. One or both of the implantable medical device and a patient programmer may store usage information that provides an objective assessment of therapy use by the patient, and allows a clinician to later improve the therapy based on the usage information.

Claims

1. A device comprising:

a processor that receives subjective rating information relating to at least one of effectiveness of delivery of neurostimulation therapy according to the parameter sets in treating symptoms of the patient or side effects experienced by the patient due to the delivery of neurostimulation therapy according to the parameter sets, stores the rating information and information relating to use of the neurostimulation therapy parameter sets to control the delivery of therapy within the memory in association with the respective parameter sets, and provides the stored information to a user,

wherein the information relating to use of the neurostimulation therapy parameters sets to control the delivery of therapy comprises information relating to at least one of a number of times or an amount of time that the neurostimulation therapy parameter sets have been used to control the delivery of the therapy.

2. The device of claim 1, wherein the processor receives adjustments made by a patient to the neurostimulation therapy parameters, stores information relating to the adjustments within the memory, and provides the information relating to the adjustments to the user.

3. The device of claim 1, wherein the processor sends the stored information to a programming device associated with the user.

4. The device of claim 1, wherein the rating information includes information relating to a plurality of metrics for rating the parameter set.

5. The device of claim 4, wherein the rating information includes numerical values for at least some of the metrics.

6. The device of claim 1, wherein the rating information comprises an overall rating for a parameter set calculated based on a number of metrics.

7. The device of claim 1, further comprising a display.

8. The device of claim 7, wherein the processor generates a histogram that illustrates percentages of a period of time that each of the parameter sets was used to provide neurostimulation therapy to the patient, and displays the histogram via the display.

9. The device of claim 7, wherein the processor generates a diagram that illustrates which of the parameter sets was being used to provide neurostimulation therapy at various times throughout a day, and displays the diagram via the display.

10. The device of claim 7, wherein the processor receives recorded information relating to neurostimulation therapy activation and deactivation, generates a diagram that illustrates the overall usage of neurostimulation therapy during consecutive time periods based on the activation and deactivation information, and displays the diagram via the display.

11. The device of claim 10, wherein the processor generates a depiction of a calendar, the time periods include at least one of days or weeks, and the processor displays the calendar via the display.

12. The device of claim 7, wherein the processor generates a trend diagram of a value of a neurostimulation program parameter over time based on the recorded information, and displays the trend diagram via the display.

13. A device comprising:

a display; and

a processor that receives recorded information relating to use of a plurality of previously defined neurostimulation therapy parameter sets by an implanted medical device to deliver neurostimulation therapy to a patient, and provides the recorded information to a user via the display, wherein each of the parameter sets includes at least one program, and each of the programs includes a plurality of neurostimulation therapy parameters,

wherein the processor receives the recorded information from at least one of an implantable medical device or a programming device associated with the patient,

wherein the processor analyzes the recorded information relating to use of the plurality of previously defined neurostimulation therapy parameter sets, and suggests neurostimulation therapy options to the user based on the analysis, and

wherein the recorded information comprises information relating to at least one of a number of times or an amount of time that the plurality of previously defined neurostimulation therapy parameter sets have been used by the implanted medical device to deliver the neurostimulation therapy to the patient.

14. The device of claim 13, wherein the processor generates a histogram that illustrates percentages of a period of time that each of the parameter sets was used to provide neurostimulation therapy to the patient, and displays the histogram via the display.

15. The device of claim 13, wherein the processor generates a diagram that illustrates which of the parameter sets was being used to provide neurostimulation therapy at various times throughout a day, and displays the diagram via the display.

16. The device of claim 13, wherein the processor receives recorded information relating to neurostimulation therapy activation and deactivation, generates a diagram that illustrates the overall usage of neurostimulation therapy during consecutive time periods based on the activation and deactivation information, and displays the diagram via the display.

17. The device of claim 16, wherein the processor generates a depiction of a calendar, the time periods include at least one of days or weeks, and the processor displays the calendar via the display.

18. The device of claim 13, wherein the processor generates a trend diagram of a value of a neurostimulation program parameter over time based on the recorded information, and displays the trend diagram via the display.

19. The device of claim 13, wherein the processor identifies a frequently used parameter set based on the recorded information, and suggests an additional program that is similar to a program of the frequently used parameter set.

20. The device of claim 19, wherein the processor compares programs of the frequently used parameter set to programs identified by at least one of a session log that includes information identifying programs tested on the patient during a programming session or a program library that stores programs according to a set of hierarchical categories, wherein each of the categories is related to a characteristic of at least one of the programs.

21. The device of claim 13, wherein the processor identifies an infrequently used parameter set, generates a list of parameter sets used to provide neurostimulation therapy to the patient that includes the infrequently used parameter set, displays the list via the display, and marks the infrequently used parameter set for removal from the list.

22. The device of claim 13, wherein the device comprises a programming device associated with the user.

23. A device comprising:
