Abstract

A system and method for selecting leadwire stimulation parameters includes a processor iteratively performing, for each of a plurality of values for a particular stimulation parameter, each value corresponding to a respective current field: (a) shifting the current field longitudinally and/or rotationally to a respective plurality of locations about the leadwire; and (b) for each of the respective plurality of locations, obtaining clinical effect information regarding a respective stimulation of the patient tissue produced by the respective current field at the respective location; and displaying a graph plotting the clinical effect information against values for the particular stimulation parameter and locations about the leadwire, and/or based on the obtained clinical effect information, identifying an optimal combination of a selected value for the particular stimulation parameter and selected location about the leadwire at which to perform a stimulation using the selected value.

Claims

1. A computer-implemented method for selecting electrical stimulation parameters for a leadwire implanted in patient tissue, the method comprising:

receiving, by a computer processor, user input of a point within a graph, the user input provided by point and click within the graph, the graph plotting obtained therapeutic effect and adverse side effect values for a plurality of values of a particular stimulation parameter against locations about the leadwire, the user-input point corresponding to a single value for the particular stimulation parameter and a single location about the leadwire;

determining, by the processor, a combination of values for the particular stimulation parameter for each of a plurality of electrodes of the leadwire; and

at least one of (a) displaying on a monitor, by the processor, the determined values of the particular stimulation parameter or (b) initiating, a signal, by the processor, to apply the determined values of the particular stimulation parameter to an implanted pulse generator that causes the leadwire to produce a stimulation.

2. The method of claim 1, wherein the locations correspond to actual locations of electrodes of the leadwire and virtual locations of electrodes of the leadwire corresponding to a current field producible by a combination of a respective subset of the electrodes of the leadwire.

3. The method of claim 1, wherein the graph is three dimensional, and further plots the obtained therapeutic effect and adverse side effect values against values for a second stimulation parameter.

4. The method of claim 1, wherein the locations differ longitudinally and rotationally about the leadwire.

5. The method of claim 4, wherein the graph is three has three dimensions, variations in longitudinal location about the leadwire being plotted along a first one of the dimensions of the graph and variations in rotational location about the leadwire being plotted along a second one of the dimensions of the graph.

6. The method of claim 1, wherein the stimulation parameter is one of i) amplitude of a current, ii) pulse width of a current, and iii) frequency of a current.

7. The method of claim 1, wherein the combination of values are applied in the step initiating a signal to apply the determined values of the particular stimulation parameter to an implanted pulse generator that causes the leadwire to produce a stimulation by interleaving current supply to different ones of a plurality of electrodes.

8. The method of claim 1, wherein the locations correspond to actual locations of electrodes of the leadwire and virtual locations of electrodes of the leadwire corresponding to a current field producible by a combination of a respective subset of the electrodes of the leadwire.

9. The method of claim 8, further comprising identifying within the graph, a region whose plotted therapeutic effect values are lower than its adverse side effect values, with a greatest distance between plotted values of the therapeutic effect and adverse side effect.

10. The method of claim 1, wherein the user-input point is shifted in response to user input of a shill instruction by selection of a control, each selection of Which is interpreted by the processor as an instruction to shift in a respective direction by a predetermined amount.

11. The method of claim 1, further comprising:

iteratively performing the following for each of the plurality of values for the particular stimulation parameter, each value corresponding to a respective current field;

positioning, by a computer processor, the current field at each of a respective plurality of locations about the leadwire; and

for each of the respective plurality of locations, obtaining, by the processor, one or more therapeutic effect or adverse side effect values regarding a respective stimulation of the patient tissue produced by the respective current field at the respective location.

12. The method of claim 11, wherein the locations differ longitudinally and rotationally about the leadwire.

13. The method of claim 11, wherein the positioning is performed by shifting the current field at least one of longitudinally and rotationally.

14. The method of claim 13, wherein the shifting is performed in response to user input of a shift instruction by selection of a control, each selection of which is interpreted by the processor as an instruction to shift in a respective direction by a predetermined amount.

15. The method of claim 14, wherein the combination of values is applied by interleaving current supply to different ones of the electrodes.

16. The method of claim 12, wherein the stimulation parameter is one of i) amplitude, ii) pulse width, and iii) frequency.

17. The method of claim 11, wherein the locations correspond to actual locations of electrodes of the leadwire and virtual locations of electrodes of the leadwire corresponding to a current field producible by a combination of a respective subset of the electrodes of the leadwire.
