SHIFTING OF ELECTRICAL STIMULATION ELECTRODE COMBINATIONS AMONG DIFFERENTLY SIZED ELECTRODE ARRAYS

摘要

The disclosure provides techniques for parameter-directed shifting of electrical stimulation electrode combinations. An 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 that are indicated by a corresponding series of parameter adjustments, where the number of shift operations along the length of a lead having a greater electrode count is greater than the number of shift operations along the length of a lead having a lesser electrode count.
