An array stimulator has a plurality of electrodes in an array, the electrodes forming a plurality of electrode pairs, and a signal generator for generating signals to the electrodes so as to generate electrical pulse in a patient to which the stimulator has been applied either transcutaneously or by implantation. Those electrical pulses form a composite pulse in the patient which stimulates the nervous system of the patient. The composite pulse has a duration between 4 μs and 1500 μs and a maximum voltage between 2V and 50V when the stimulator is implanted, and 15V to 500V when applied transcutaneously. The electrical pulses themselves are significantly shorter duration than the composite pulse, so they stimulate the nervous system of the patient much less than the composite pulse or not at all. |
