Abstract: A medical device includes a shaft including a distal end including a passive electrode that defines a central opening extending through the passive electrode, and an active electrode within the central opening. The active electrode is movable between at least an extended position in which the active electrode does not contact the passive electrode, and a retracted position in which the active electrode contacts the passive electrode.
