Pyloric valve corking devices are disclosed herein that generally include an occluding member, expanding from a first configuration to a larger second configuration, and a bridging member extending from the occluding member. The bridging member has a length that is adapted to pass at least partially through the gastric opening, so to enable the occluding member to obstruct the gastric opening, and that is also adapted to permit the occluding member to intermittently move relative to the gastric opening. A second occluding member may be attached to the distal end of the bridging member. The reduction in flow of gastric contents into the duodenum can be actively regulated using a pump or valve, or can be passively regulated with movements of the occluding device.
