1. An implantable device configured to be placed in a patient's stomach and duodenum region transorally without surgery to treat and prevent obesity, comprising: an inflatable gastric balloon defining an inflatable space and residing in the patient's stomach and formed of a material that can withstand the acidic environment of the patient's stomach for at least 6 months, the gastric balloon having an inflated volume sufficient to ensure that the gastric balloon cannot pass through patient's pylorus; an inflatable intra-duodenal balloon defining an inflatable space and having a deflated volume that will fit within the patient's duodenum and allow food to pass and an inflated volume that contacts the walls of the duodenum; a fluid transfer conduit coupled between the inflatable space of the gastric balloon and the inflatable space of the intra-duodenal balloon; and a first valve located between, and in fluid communication with, the inflatable space of the gastric balloon and the inflatable space of the intra-duodenal balloon, the first valve configured to allow fluid to flow freely from the inflatable space of the gastric balloon to the fluid transfer conduit and limit backflow of fluid from the fluid transfer conduit to the inflatable space of the gastric balloon.
