Gastrointestinal liners that are deployed through an endoscopic tube. They are designed to cover a segment of the small intestine close to the stomach to promote weight loss and improve diabetes treatment in obese patients. These liners typically consist of thin and flexible polymeric tubes inserted through the mouth using an endoscopic tube; the proximal end of the liner is fixed (e.g., anchored) into the segment of the small intestine near to the stomach. Food passes through the liner without contact with the covered segment of the intestine, thereby preventing the absorption in that segment of the intestine. The liner may be removed at any time using a retrieval system that is also inserted through the mouth. Endoscopically-deployed gastrointestinal liners are mainly intended for bariatric patients who suffer also from diabetes.
