Abstract: A method comprises: selecting a plurality of electrodes of one or more stimulation leads, the selected plurality of electrodes defining a two-dimensional region; determining a calibration value for stimulation points defined by the plurality of electrodes; selecting a stimulation point within a boundary formed by the two-dimensional region; identifying points on the boundary that are axially displaced relative to the selected stimulation point; automatically calculating boundary calibration values for identified points, each boundary calibration value being calculated as a linear interpolation of calibration values of a pair of stimulation points determined for the plurality of electrodes; automatically assigning a calibration value to the selected stimulation point that is a summation of the calculated boundary calibration values; and using the automatically assigned calibration value for the stimulation point to control an amplitude of stimulation pulses applied to the patient.

Abstract: In one embodiment, a method for assisting programming a pulse generator comprises: defining a set of unique electrode combinations in the controller device, each electrode combination within the set providing a unique locus of stimulation for a single stimulation pulse applied at a base location relative to loci of stimulation of other electrode combinations, the set of unique electrode combinations defining a two-dimensional range of multiple loci of stimulation; providing one or more user interfaces to the clinician to control pulse generation and delivery by the single-source pulse generator; and processing input from the clinician related to relocation of a locus of stimulation, the processing comprising (i) automatically selecting an electrode combination from the set, and (ii) automatically modifying an electrode combination used by the single-source pulse generator to deliver electrical stimulation pulses to the selected electrode combination.
