    Abstract: An electrode treatment device includes an electrode strip arranged in the shape of a helix with a first end of the electrode strip attached to an elongate flexible body, such as a catheter tube, and a second end of the electrode strip attached to a flexible shaft that extends from the body. When the helical electrode is contracted around the body and/or shaft, the device may be less than 2 mm in diameter to facilitate endoluminal insertion and treatment of gastrointestinal or lung tissue, for example. The shaft is rotatable relative to the body to radially expand the helix to a deployed position in apposition to target tissue for electrosurgical treatment (e.g., treatment in a lumen). The electrode strip may consist of conductive foil or may comprise a flexible printed circuit with one or more electrodes formed thereon. The device may be operated by a robotic manipulator.
