Abstract:
1. An intragastric implant for use in a patient, the patient having an esophagus leading to a stomach, the stomach in communication with intestines through a pyloric valve, the intestines adjacent the pyloric valve including a duodenum with a duodenal bulb and bends, the intragastric implant comprising: an intragastric anchor adapted to extend from the fundus toward the pyloric valve in the patient when deployed within the patient's gastrointestinal tract, the anchor comprising a rigid or semi-rigid elongate element having a width dimension and a length dimension, the width dimension being less than the length dimension, the elongate element being dimensioned sufficiently small to pass through the esophagus into the stomach and the length dimension being sufficiently long such that the length dimension inhibits passage of the anchor beyond the bends of the duodenum so that the anchor provides non-penetrating anchoring within the gastrointestinal tract; and an intestinal bypass sleeve coupled to the anchor, the intestinal bypass sleeve having a central passage extending from a proximal opening to a distal outlet, the distal outlet configured to be positioned in the intestines while the intragastric anchor maintains the proximal opening adjacent the stomach so that food passes through the intestinal bypass sleeve.
