Abstract: A medical device includes an electrode shaft and a tip. The electrode shaft is configured to deliver energy to a target site and includes an electrode shaft lumen configured to deliver fluid to the target site. The tip is coupled to a distal tip of the electrode shaft. The tip includes an inner portion of conductive material and an exterior layer of insulative material. The tip includes a tip lumen fluidly connected to the electrode shaft lumen and configured to deliver fluid to the target site.
