Abstract

An electrosurgical balloon includes an inflatable balloon body formed of a non-conductive substrate material. One or more electrodes are disposed on an exterior surface of the balloon body. The electrodes can include a pair of bipolar electrodes, and the balloon body can have at least one fluid outlet hole configured to provide fluid to the pair of bipolar electrodes. A second inflatable balloon body can be disposed inside the first inflatable balloon body. The electrosurgical balloon can be incorporated into a catheter assembly, in which the electrosurgical balloon is a balloon electrode tip at a distal end of a catheter.
