Method and apparatus for gastrointestinal tract ablation for treatment of obesity
First Claim
1. A method of ablationally-treating tissue at a target area in a gastrointestinal tract of a patient with a pathophysiological metabolic condition comprising:
- delivering energy from an ablation structure to a tissue surface within the target area, the target area being a portion of the gastrointestinal tract that includes at least a portion of a jejunum; and
controlling the delivery of energy to the tissue surface within the target area and into a depth of tissue within the target area to treat the pathophysiological metabolic condition.

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.
