Abstract
Apparatus and methods for reducing nerve stimulation in electrosurgical instruments utilizing electrically isolated pairs of electrodes are disclosed. At least two pairs of electrodes may be configured to create at least two opposing currents which effectively cancel one another such that a net current flow is inhibited from developing within surrounding tissue structures to mitigate or eliminate undesired electrical stimulation of the tissue.
