Abstract
Several configurations for single and multi-needle electromyographic (EMG) recording electrodes for intraoperative nerve integrity monitoring are disclosed, one of which may concern a multi-needle electrode including one or more cables that are connected directly or indirectly to a nerve integrity monitor, a single hub connected to the one or more cables, and at least two needle electrodes connected to the single hub each having first and second bends along the line of insertion into a patient, wherein the first bend occurs at the hub connection in a downward direction and the second bend occurs in an upward direction from the first bend creating a proximal needle segment from the hub to the second bend and a terminal needle segment from the second bend to the end of each needle.
