Abstract

An electrosurgical device includes a tubular shaft defining a shaft lumen, and a tubular electrode defining an electrode lumen, the electrode being coupled to the shaft. In a straight configuration, the electrode is configured to retain fluid within the electrode lumen, and, in a bent configuration, the electrode is configured to release fluid from within the electrode lumen to an exterior of the electrode.
