Abstract
A self-adjusting gastric band is automatically adjustable without complicated fluid control mechanisms, flow rate limiting devices, and/or valves. The self-adjusting gastric band may automatically adjust to allow a large bolus of food to pass through a constriction in the patient's stomach formed by the gastric band. The self-adjusting gastric band comprises an inflatable portion that is disposable about an esophageal-gastric junction of the patient. A first compliant portion is coupled to the inflatable portion. The first compliant portion automatically relaxes the constriction formed by the self-adjusting gastric band and allows the large bolus to pass through the constriction. After the bolus passes through the constriction, the self-adjusting gastric band automatically returns to its previous state.
