Gastric bands for reducing obstructions

摘要

Generally described herein are apparatus, systems and methods related to gastric bands which provide increased compliance to reduce food obstructions and/or reduces over restriction causing symptoms such as gastric enlargement and pouch dilatation. In one embodiment, a dual ringed reservoir band or inflatable portion is provided. In one embodiment, an additional ring or a middle pouch may be added to the dual ringed reservoir band. The addition of an additional ring or middle pouch may further increase band compliance resulting in even fewer food obstructions. In another embodiment, one or more funnels can also be implemented into a gastric banding system to induce satiety and/or for guiding a bolus through the gastric band.
