1. A device for delivering therapeutic energy to tissue, comprising:

  • a housing;

    a plurality of electrodes, each electrode including;

    a proximal section longitudinally extending from within the housing and having a longitudinal axis;

    an intermediate section extending from the proximal section;

    a distal section extending longitudinally from the intermediate section;

    a rotating device coupled to the proximal sections of the plurality of electrodes and adapted to rotate the plurality of electrodes by rotating the proximal section of each electrode about its longitudinal axis to move the distal sections of the electrodes from a first radial state to a second radial state; and

    wherein in the first radial state, at least a portion of the intermediate section of at least one electrode overlaps at least a portion of the intermediate section of an adjacent electrode.
