Abstract
A stationary dilator has one or more electrodes in the distal region that are rotatable around the longitudinal axis of the dilator. The one or more electrodes are operable to deliver electrical stimulation signals to tissue through which the dilator is passed. The stimulation signals can be used for determining nerve directionality and optionally nerve proximity during surgical procedures involving the presence of neural structures.
