Patent ID: 8332039

Claim:
A method of using one or more calibration values for one or more stimulation leads implanted within the epidural space of a patient to control electrical stimulation of the patient, the method comprising: selecting a plurality of electrodes of the one or more stimulation leads, the selected plurality of electrodes defining a two-dimensional region of stimulation points; determining a respective calibration value for each stimulation point 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 on the boundary, 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 weighted summation of the calculated boundary calibration values; and using the automatically assigned calibration value for the selected stimulation point to control an amplitude of stimulation pulses applied to the patient.
