    Abstract: Systems and methods are provided for positioning and stabilizing an external instrument during insertion of the instrument through the oral cavity (e.g., insertion of a catheter through the oral cavity and into the esophagus or cardia for treatment of gastroesophageal reflux disease (GERD)). The systems and methods provide a gripping tool for association with a bite block, capable of selectively moving between an open position in which the instrument may be inserted or removed, and a closed position in which the external instrument is held in a fixed position.

    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.

    Abstract: Devices and methods are provided for ablational treatment of regions of the digestive tract in post-bariatric surgery patients who fail to achieve or maintain the desired weight loss. Bariatric procedures include Roux-en-Y gastric bypass, biliopancreatic diversion, and sleeve gastrectomy. These procedures reconstruct gastrointestinal tract features, creating pouches, stoma, and tubes that restrict and/or divert the digestive flow. Post-surgical dilation of altered structures is common and diminishes their bariatric effectiveness. Ablation of compromised structures can reduce their size and compliance, restoring bariatric effectiveness. Ablation, as provided the invention, starts at the mucosa and penetrates deeper into the gastrointestinal wall in a controlled manner. Control may also be provided by a fractional ablation that ablates some tissue within a target region and leaves a portion substantially unaffected. 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.

    Abstract translation: 提供了设备和方法，用于消除不能达到或保持所需体重减轻的减肥手术患者消化道区域的消融。 减肥手术包括Roux-en-Y胃旁路，胆胰管引流和套管胃切除术。 这些程序重建胃肠道特征，产生限制和/或转移消化道的小袋，造口和管。 改变结构的手术后扩张是常见的，并且减轻了他们的减肥效果。 消融受损结构可减少其尺寸和依从性，恢复减肥效果。 根据本发明，消融从粘膜开始并以受控的方式深入胃肠壁。 控制也可以通过消融目标区域内的一些组织并使基本上不受影响的部分的部分消融来提供。 该装置的实施例包括跨越360度的消融电极阵列和跨越小于360度的弧的阵列。
