ABSTRACT:
Device and method for monitoring evoked potentials and/or electroencephalograms including a novel unipolar spiral coil electrode. The unipolar electrode includes a user holder member formed of non-conductive material and having an outside surface adapted to be grasped by the physician's fingers. A spiral coil formed of a conductive material and having a pointed or beveled tip extends forward from the user holder member. The coil is directly attached to the user holder member such that when the user holder member is grasped by the physician's fingers, pressed against the patient's skin and rotated, the tip pierces the patient's skin and the spiral coil is twisted through the epidermis to a distance sufficient to secure the user holder member to the patient but not great enough to pierce the underlying bone. To assist in manipulating the user holder member, the user holder member on its outer surface includes a friction increasing device such as a pair of projecting ears, a knurled surface, or a knob. An electrically conducting wire connects to the holder member, and thus the spiral coil, either through a permanent or a removable connection, and exits preferably rearwardly from the holder member. The wire has an opposite connector end adapted to be connected to a device for monitoring the electrical activity of the brain.
