Abstract: A medical device includes an elongate body, an expandable treatment element, a plurality of flexible shafts, and a plurality of electrodes. The elongate body has a proximal portion and a distal portion opposite the proximal portion. The expandable treatment element is coupled to the elongate body to receive a fluid and, in some examples, is anchored to the plurality of flexible shafts with a plurality of retention elements. In some examples, each flexible shaft of the plurality of flexible shafts has a braided configuration. Each electrode of the plurality of electrodes is attached and electrically coupled to a respective flexible shaft of the plurality of flexible shafts.
