摘要：
The present invention provides for a gastric banding system including an adjustment system that automatically increases the size of a constricted portion of a gastric lumen in response to an obstruction passing through the gastric lumen. The size of the constricted portion of the gastric lumen increases rapidly when the obstruction approaches a gastric band constricting the lumen. The adjustment system is also configured to slowly return the constricted gastric lumen to an equilibrium size the lumen had prior to the obstruction passing through the lumen. Various embodiments of gastric banding systems and adjustment systems are disclosed.
