Abstract
Devices and methods for ablating tissue in the wall of various organs of the gastrointestinal tract of a patient in order to cure or ameliorate metabolic pathophysiological conditions such as obesity, insulin resistance, or type 2 diabetes mellitus are provided. Ablational treatment of target areas may be fractional or partial, rendering a post-treatment portion of target tissue ablated and another portion that is substantially intact. Fractional ablation is achieved by controlling the delivery of ablational energy across the surface area being treated, and controlling the depth of energy penetration into tissue. Surface area control of energy delivery may controlled by the spatial pattern of distributed ablation elements or by the selective activation of a subset of a dense pattern of ablation elements. Embodiments of the device include an ablational electrode array that spans 360 degrees and an array that spans an arc of less than 360 degrees.
