Abstract
Generally described herein are automatic, self-adjusting, gastric banding systems and improvements thereof, that are capable of automatically relaxing and contracting in response to a large bolus passing through the area of a patient's stomach constricted by a gastric band. Alternatively, and/or in addition in one or more embodiments, the gastric banding systems described herein may also help prevent pouch dilatation and/or erosion. The apparatus and systems described herein aid in facilitating obesity control and/or treating obesity-related diseases while generally being non-invasive once implanted. Furthermore, certain embodiments of the self-adjusting gastric banding systems disclosed herein are automatically adjustable without complicated fluid control mechanisms, flow rate limiting devices, and/or valves. The automatic adjustments may also be made in response to other changes in the patient's esophageal-gastric junction, for example, in response to size, shape, and or location changes.
