Shifting of electrical stimulation electrode combinations among differently sized electrode arrays
First Claim
1. A method comprising:
- delivering electrical stimulation via an electrode combination comprising at least one active electrode in a first array of electrodes and at least one active electrode in a second array of electrodes, wherein the second array includes a greater number of electrodes than the first array, wherein each electrode of the first array is positioned at a respective level within the first array, and wherein each electrode of the second array is positioned at a respective level within the second array; and
shifting the electrical stimulation to different electrode combinations in a series of shift operations, wherein one of the shift operations includes shifting a position of all active electrodes in the second array while maintaining a position of all active electrodes in the first array, and wherein shifting the position of all active electrodes in the second array comprises performing a single level shift of the position of all active electrodes in the second array.

Abstract
The disclosure provides techniques for parameter-directed shifting of electrical stimulation electrode combinations. An external programmer permits a user to shift electrode combinations, e.g., along the length of a lead or leads. The external programmer accepts shift input and causes an electrical stimulator to shift electrode combinations as indicated by the input. Different sets of electrodes may have different electrode counts. For example, an array of electrodes carried by one lead may have a greater number of electrodes than an array of electrodes carried on another lead. The disclosure provides techniques for shifting electrode combinations among leads with different electrode counts. For example, an external programmer may execute shifts in a series of shift operations, where the number of shift operations along the length of a lead having a greater electrode count is greater than the number of shift steps along the length of a lead having a lesser electrode count.
