  • Publication number: 20120022322
    Abstract: Methods and devices for treating obesity. Pressure is applied to gastric walls in at least one segment of a stomach such that the pressure distends the gastric walls and induces satiety. A hollow capsule can be used to distend the gastric walls. Alternatively, a doughnut- shaped ring may be inflated to an amount sufficient to create intragastric tension and induce satiety. A c-ring including at least one balloon may be placed at a segment of the stomach, where the balloon inflates to a size that creates tension at the segment. A biocompatible material can be injected into the fundus and antrum of the stomach to stiffen the gastric wall to create a fullness feeling.

  • Patent number: 8021355
    Abstract: Embodiments of systems, kits, and methods to perform transgastric procedures to removing visceral fat in the peritoneal cavity are described. Am embodiment includes deliberately breaching a wall of a gastrointestinal tract to enter the peritoneal cavity to physically remove visceral fat adjacent or on outer surfaces of organs located within the peritoneal cavity. A user can identify regions of visceral fat desired to be removed. A user can insert an instrument through the mouth into the stomach of the patient. The user makes an incision in the wall of the organ adjacent the visceral fat to be removed. Using visual guidance for the instrument, the user passes a distal end of the instrument through an opening formed by the incision into the peritoneal cavity. A user utilizes removes the visceral fat from outer surfaces of the organ, the opening is closed, and the tool is removed from the patient.

  • Publication number: 20110034967
    Abstract: The disclosure provides a method of treatment for obesity, in an individual in need thereof, by administering electrical stimulation at dual sites in the gastrointestinal tract. The electrical stimulations are administered by positioning bipolar stimulatory electrodes in contact with the gastric and dudenol cavities, along afferent vagal neural pathways, in the gastrointestinal tract. The electrical stimulations thus administered, activate the vagal afferents associated with the gastric and dudenol sites in the gastrointestinal tract. The activation of vagal afferents modulates the gastrointestinal peptide satiety hormones. Further, the disclosure provides a method of treatment for eating disorders, in an individual in need thereof, by administering electrical stimulation at dual sites, along afferent vagal neural pathways, in the gastrointestinal tract.
