Abstract
A device for delivering therapeutic energy to tissue is provided. The device includes a housing and a rotating device coupled to the housing. The device includes a plurality of electrodes, each electrode including: (i) a proximal section longitudinally extending from within the housing to an exterior of the housing and having a longitudinal axis; (ii) an intermediate section extending from the proximal section; and (iii) a distal section extending longitudinally from the intermediate section. The rotating device is coupled to the proximal sections of the plurality of electrodes and adapted to rotate the distal section of the electrodes so that distance between at least two electrodes changes, so that the electrodes can be placed in a compact configuration or an expanded configuration to provide for a treatment region larger than the size of the opening for insertion.
