Therapeutic energy delivery device with rotational mechanism
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; 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.

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.
