20150335453 | Treatment for Obesity by Selectively Clipping the Gastric Fundus to Modify Blood Flow - Weight loss can be promoted by folding a portion of the gastric fundus of a human subject's stomach in proximity to the distal portion of the subject's left gastric artery (including its smaller branches), and clipping the tissue so that it stays in the folded state. The clips cause endovascular flow reduction or interruption to the fundus. The reduced or interrupted blood flow decreases the production of the hormone ghrelin, which reduces the subject's appetite, thereby promoting weight loss.
