Abstract
A flexible bipolar electrode for neurosurgery includes an inner hypotube defining an irrigation passageway and a hollow outer electrode surrounding the hypotube, with the outer electrode and hypotube together establishing a bipolar electrode. An empty void is established between the electrodes to facilitate flexibility of the bipolar electrode when, for example, the electrode is advanced through a curved lumen of a neuroendoscopy instrument.
