Abstract

A therapy program for peripheral nerve field stimulation (PNFS) may be selected based on user input indicating a desired therapeutic effect for a user-specified region in which a patient feels pain. In other examples, PNFS may be programmed based on input from a user selecting at least one region from among a plurality of regions in which the patient experiences pain. In addition, the PNFS may be programmed based on user input defining an aspect of PNFS for the selected region, such as a relative intensity of PNFS delivered to at least two selected regions, a balance of PNFS between at least two regions, a desired shift in PNFS from a first region to a second region, or an extent to which a first stimulation field within a first region overlaps with a second stimulation field in a second region.

Claims

1. A method comprising:

presenting, via a user interface, a list of predetermined therapeutic effects for peripheral nerve field stimulation that is delivered to a region of a body of a patient in which the patient experiences pain via at least one electrode implanted in the region;

receiving, via a user interface, input indicating a desired therapeutic effect for the region of the body, the input selecting the desired therapeutic effect from the list of predetermined therapeutic effects; and

determining, with a processor, a therapy program for delivering the peripheral nerve field stimulation to the region based on the input.

2. The method of claim 1, wherein a programmer comprises the processor, further comprising transmitting, with the programmer, the therapy program to a medical device that delivers the peripheral nerve field stimulation to the region of the body of the patient.

3. The method of claim 1, further comprising delivering, by a medical device, the peripheral nerve field stimulation to the patient according to the therapy program.

4. The method of claim 1, wherein the list of predetermined therapeutic effects comprises a muscle activation effect, a production of endorphins effect or a paresthesia effect.

5. The method of claim 1, wherein determining a therapy program comprises determining a stimulation frequency range to produce the desired therapeutic effect, and wherein the stimulation frequency range is determined on per-patient basis.

6. The method of claim 1, wherein receiving the input indicating the desired therapeutic effect comprises receiving input selecting a stimulation frequency range for the peripheral nerve field stimulation.

7. The method of claim 6, wherein the stimulation frequency range is selected from at least a first range of about less than about 10 Hertz, a second range of about 10 Hertz to about 30 Hertz, and a third range of greater than about 30 Hertz.

8. The method of claim 1, wherein the input comprises a first input indicating a first desired therapeutic effect for the region of the body and determining a therapy program comprises determining a first therapy program based on the first input, the method further comprising receiving a second input indicating a second desired therapeutic effect for the region of the body that is different than the first desired therapeutic effect, and determining a second therapy program based on the second input, wherein the second therapy program defines at least one therapy parameter value that differs from the first therapy program.

9. The method of claim 8, further comprising controlling a medical device to deliver peripheral nerve field stimulation to the region of the body of the patient according to the first therapy program and the second therapy program by at least interleaving delivery of stimulation signals defined by the first therapy program with the delivery of stimulation signals defined by the second therapy program.

10. The method of claim 8, further comprising controlling a medical device to deliver peripheral nerve field stimulation to the region of the body of the patient according to the first and second therapy programs substantially simultaneously.

11. The method of claim 1, wherein determining the therapy program comprises selecting the therapy program from a plurality of stored therapy programs based on the input indicating the desired therapeutic effect.

12. The method of claim 1, further comprising receiving, via the user interface, a stimulation vector input that indicates a direction of the peripheral nerve field stimulation, wherein determining the therapy program comprises selecting the therapy program from a plurality of stored therapy programs based on the input indicating the desired therapeutic effect and the stimulation vector input.

26. The method of claim 1, wherein the list of predetermined therapeutic effects comprises at least one of a muscle activation effect or a production of endorphins effect.

13. A system comprising:

a user interface; and

a processor configured to present, via the user interface, a list of predetermined therapeutic effects for peripheral nerve field stimulation that is delivered to a region of the body of a patient in which the patient experiences pain via at least one electrode implanted in the region, and receive input via the user interface, wherein the input indicates a desired therapeutic effect for the region of the body, the input selecting the desired therapeutic effect from the list of predetermined therapeutic effects wherein the processor is configured to determine a therapy program for delivering peripheral nerve field stimulation to the region based on the input.

14. The system of claim 13, further comprising a medical device programmer that comprises the processor and the user interface.

15. The system of claim 13, further comprising a medical device programmer that comprises the user interface and a medical device that comprises the processor, wherein the medical device is configured to deliver the peripheral nerve field stimulation to the region of the body of the patient.

16. The system of claim 13, wherein the list of predetermined desired therapeutic effects comprises at least one of a muscle activation effect, a production of endorphins effect or a paresthesia effect.

17. The system of claim 13, wherein the input indicates a stimulation frequency range for the peripheral nerve field stimulation.

18. The system of claim 17, wherein the stimulation frequency range is selected from at least a first range of about less than about 10 Hertz, a second range of about 10 Hertz to about 30 Hertz, and a third range of greater than about 30 Hertz.

19. The system of claim 13, wherein the input comprises a first input indicating a first desired therapeutic effect for the region of the body and the therapy program comprises a first therapy program based on the first input, wherein the processor is configured to receive, via the user interface, a second input indicating a second desired therapeutic effect for the region of the body that is different than the first desired therapeutic effect, and determine a second therapy program based on the second input, wherein the second therapy program defines at least one therapy parameter value that differs from the first therapy program.

20. The system of claim 19, wherein the processor is configured to control a medical device to deliver peripheral nerve field stimulation to the region of the body of the patient according to the first and second therapy programs by interleaving delivery of stimulation signals defined by the first therapy program with the delivery of stimulation signals defined by the second therapy program.

21. The system of claim 19, wherein the processor is configured to control a medical device to deliver peripheral nerve field stimulation by delivering the peripheral nerve field stimulation to the region according to the first and second therapy programs substantially simultaneously.

22. The system of claim 13, further comprising a memory that stores a plurality of therapy programs, wherein the processor is configured to determine the therapy program by selecting the therapy program from the plurality of therapy programs stored in the memory.

23. The system of claim 13, wherein the processor is configured to receive a stimulation vector input via the user interface and determine the therapy program based on the input indicating the desired therapeutic effect and the stimulation vector input.

27. The system of claim 13, wherein the list of predetermined therapeutic effects comprises at least one of a muscle activation effect or a production of endorphins effect.
