  • Publication number: 20170079822
    Abstract: Obesity treatment apparatus and methods are described herein involving gastric recycling of food are described herein. In one or more embodiments, the gastric recycling apparatus keeps returning chyme to the stomach increasing satiety signals and delaying hunger signals associated with an empty stomach. It may also may slow the emptying of the stomach as the caloric load in the stomach delays emptying and/or limit absorption of food within the small intestine by delivering at least a portion of food passing through the small intestine back into the stomach.

  • Publication number: 20070265709
    Abstract: Devices and methods for achieving weight loss in obese and morbidly obese patients are disclosed. The invention combines a gastric and/or small bowel bypass (in which ingested food bypasses the stomach and, optionally, at least a portion of the small bowel) and a satiety device in the form of one or more expandable chambers, that tend to induce a feeling of satiety after the patient has consumed a relatively small amount of food. This combination of gastric and/or small bowel bypass and satiety structure may be delivered and removed using minimally invasive procedures such as an endoscope. In some instances, the gastric and/or small bowel bypass device itself can form the satiety structure. In other devices, the gastric bypass may be independent of the satiety structure (which may be provided as one or more expandable chambers).

  • Publication number: 20060020277
    Abstract: Gastric volume of a patient is reduced by deploying an endoscope into a stomach through the esophagus. A plurality of anterior anchors are affixed to the anterior wall of the stomach. The anterior anchors are distributed along an anterior line of the stomach wall beginning near the cardia region and extending toward the stomach exit. A plurality of posterior anchors are affixed to the posterior wall of the stomach. The posterior anchors are distributed along a posterior line of the stomach wall beginning near the cardia region and toward the stomach exit. The anchor line and the stomach wall are drawn towards the posterior line of the stomach wall to reduce gastric volume.
