First Claim
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.

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.

17. A method for treating a tissue, comprising:
-
providing a therapeutic device wherein the therapeutic device comprises; 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 laterally from the proximal section; a distal section extending longitudinally from the intermediate section; a rotating device coupled to the proximal sections of the 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; an elongated shaft having a proximal end, a distal end, and a longitudinal axis and wherein the proximal end of the elongated shaft is coupled to at least a portion of the housing; inserting at least a portion of the therapeutic device into a body; rotating the plurality of electrodes by rotating the proximal section of each electrode about its longitudinal axis thereby causing the distal sections of the electrodes to move radially outward from a first radial state to a second radial state; positioning the distal sections in the tissue; delivering therapeutic energy through the electrodes to treat the tissue. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
