Abstract

Methods and systems for selecting stimulation parameters using targeting and steering techniques are presented. For example, a method or system (via actions performed by a processor) can include receiving a name of an anatomical or physiological target or a name of a disease or disorder; receiving a clinical goal; and using at least 1) the anatomical or physiological target or disease or disorder and 2) the clinical goal, selecting a set of stimulation parameters. Another method or system (via actions performed by its processor) can include receiving a first set of stimulation parameters; receiving a command to alter the first set of stimulation parameters that does not include, or is not composed exclusively of, a numerical value for any of the stimulation parameters; and modifying the first set of stimulation parameters to create a second set of stimulation parameters based on the command.

Claims (33)

1. A system for identifying a set of stimulation parameters, the system comprising:

a computer processor configured and arranged to perform the following actions:

providing a model of a lead comprising a plurality of electrodes, wherein the plurality of electrodes comprises a plurality of segmented electrodes forming at least one set of segmented electrodes, wherein each set of segmented electrodes comprises two or more of the segmented electrodes disposed around a circumference of the lead at a same longitudinal position along the lead;

receiving a selection of a target point external to the model of the lead;

projecting a straight line from the target point onto a surface of the model of the lead to identify a virtual electrode on the model of the lead; and

selecting a set of stimulation parameters for at least one of the electrodes to approximate an electrical field generated from the virtual electrode.

2. The system of claim 1 , wherein projecting the target point comprises projecting the target point onto a nearest point of the surface of the model of the lead to identify the virtual electrode.

3. The system of claim 1 , wherein the actions further comprise calculating the electrical field in a region that does not overlap with the lead and is bounded by a plane tangent to the lead at the virtual electrode.

4. The system of claim 1 , wherein the electrical field is a scalar potential field, a vector field, or a field of Hamiltonians of a divergence of an electrical field.

5. The system of claim 1 , wherein the actions further comprise receiving a user modification of at least one of the stimulation parameters.

6. The system of claim 1 , wherein the actions further comprise defining at least one guarding electrode adjacent the virtual electrode.

7. The system of claim 6 , wherein defining at least one guarding electrode comprises defining two guarding electrodes circumferentially disposed on opposite sides of the virtual electrode.

8. The system of claim 1 , wherein the virtual electrode is modeled as a monopolar point source.

9. The system of claim 1 , wherein the actions further comprise receiving a user modification to modify the electrical field radially.

10. The system of claim 1 , wherein the actions further comprise receiving a user modification to modify the electrical field longitudinally.

11. The system of claim 1 , wherein selecting the set of stimulation parameters comprises selecting two or more of the electrodes to approximate the electrical field generated by the virtual electrode.

12. The system of claim 9 , wherein receiving a user modification comprises receiving the user modification to spread the electrical field radially.

13. The system of claim 9 , wherein receiving a user modification comprises receiving the user modification to focus the electrical field radially.

14. The system of claim 10 , wherein receiving a user modification comprises receiving the user modification to spread the electrical field longitudinally.

15. The system of claim 10 , wherein receiving a user modification comprises receiving the user modification to focus the electrical field longitudinally.

16. A method for identifying a set of stimulation parameters, the method comprising:

providing a model of a lead comprising a plurality of electrodes, wherein the plurality of electrodes comprises a plurality of segmented electrodes forming at least one set of segmented electrodes, wherein each set of segmented electrodes comprises two or more of the segmented electrodes disposed around a circumference of the lead at a same longitudinal position along the lead;

receiving a selection of a target point external to the model of the lead;

projecting a straight line from the target point onto a surface of the model of the lead to identify a virtual electrode on the model of the lead; and

selecting a set of stimulation parameters for at least one of the electrodes to approximate an electrical field generated from the virtual electrode.

17. The method of claim 16 , wherein the actions further comprise calculating the electrical field in a region that does not overlap with the lead and is bounded by a plane tangent to the lead at the virtual electrode.

18. The method of claim 16 , wherein the actions further comprise receiving a user modification of at least one of the stimulation parameters.

19. The method of claim 16 , wherein the actions further comprise defining at least one guarding electrode adjacent the virtual electrode.

20. A non-transitory computer-readable medium having processor-executable instructions for identifying a set of stimulation parameters, the processor-executable instructions when installed onto a device enable the device to perform actions, including:

providing a model of a lead comprising a plurality of electrodes, wherein the plurality of electrodes comprises a plurality of segmented electrodes forming at least one set of segmented electrodes, wherein each set of segmented electrodes comprises two or more of the segmented electrodes disposed around a circumference of the lead at a same longitudinal position along the lead;

receiving a selection of a target point external to the model of the lead;

projecting a straight line from the target point onto a surface of the model of the lead to identify a virtual electrode on the model of the lead; and

selecting a set of stimulation parameters for at least one of the electrodes to approximate an electrical field generated from the virtual electrode.
