An electrode assembly, for the electrosurgical removal of tissue immersed in an electrically-conductive liquid, comprises an elongate support structure (12S) including at least a pair of conductors (12A, 12B) for carrying radio frequency electrosurgical currents. An electrically-insulative body (34) is mounted at a distal end of the support structure (12S), and extends transversely with respect to the support structure. A transversely-extending , conductive tissue treatment electrode (36) is secured to one side of the insulative body (34), and is electrically connected to one of the conductors . A transversely-extending, conductive return electrode (38) is secured to an opposite side of the insulative body (34).
