Abstract: Apparatuses, systems, and methods are disclosed for providing controlled delivery of energy treatment to a tissue site. The systems, apparatuses, and methods may include designs with features for efficiently deploying and adjusting electrodes at a tissue site for treatment and for facilitating retraction of the electrodes back into a housing after completion of treatment for removal. The systems, apparatuses, and methods may further include an expansion member for radially expanding the flexible substrate to aid in positioning the electrodes adjacent the tissue to facilitate treatment.

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.

Abstract: Apparatuses, systems, and methods are disclosed for providing controlled delivery of energy treatment to a tissue site. The systems, apparatuses, and methods may include medical instrument designs with features for retaining a flexible substrate with an electrode array in position against an expandable member during delivery to the tissue site, treatment, and retraction from the tissue site. The medical instrument further includes features for retaining the flexible substrate in a compact, stowed configuration during delivery and for retracting the flexible substrate post-deployment to facilitate retraction of the medical instrument after completion of treatment.
