Abstract:
1. A method, comprising: providing a neurostimulator that includes a stimulation circuit, an enclosure housing the stimulation circuit therein, the enclosure having at least one conductive area, and a plurality of distal electrodes coupled to the stimulation circuit through the enclosure; operating the stimulation circuit to energize a first subset of the distal electrodes with a first polarity; operating the stimulation circuit to energize a second subset of the distal electrodes with a second polarity opposite the first polarity, the second subset being different from the first subset; operating the stimulation circuit to energize the enclosure with one of the first and second polarities; and determining a perception threshold current level and a pain threshold current level at the enclosure during a calibration stage, and wherein the operating of the stimulation circuit to energize the enclosure is performed such that an electrical current at the enclosure is capped at one of: the perception threshold current level and the pain threshold current level.
