Abstract
A nerve interface device including at least one cuff portion having an assembled position in which the cuff portion forms at least part of a passageway for receiving a nerve along a longitudinal axis passing through the passageway; and first and second rings of electrodes mounted on the at least one cuff portion, each ring of electrodes including a plurality of electrodes. Each electrode in the first ring has a corresponding longitudinally-aligned electrode in the second ring so as to form a plurality of pairs of electrodes spaced apart from each other along the longitudinal axis. The plurality of pairs of electrodes includes at least a first pair of electrodes, the first pair of electrodes mounted on the at least one cuff portion. The at least one cuff portion includes an asymmetric configuration about a central axis perpendicular to the longitudinal cuff axis.
