An obesity treatment device for deploying in a stomach of a patient, comprising:

• a plurality of adjacent, spaced apart inflatable space-filling compartments, wherein each compartment of the plurality of inflatable space-filling compartments has a respective inflated state volume that is maintained during treatment of the patient;
• and
• a valve system for introducing a fluid into each compartment of the plurality of inflatable space-filling compartments and for retaining, upon inflation, fluid in the plurality of inflatable space-filling compartments, wherein
• the valve system comprises a respective valve structure for introducing fluid into each inflatable space-filling compartment of the plurality of inflatable space-filling compartments, wherein each respective valve structure includes at least a first valve in series with a second valve;
• wherein the obesity treatment device is to form, upon at least partially filling the plurality of inflatable space-filling compartments, to a curved shape conforming to a natural three-dimensional kidney shape of the stomach such that an outer surface of the obesity treatment device aligns against greater and lesser curvatures of the stomach.

A method for deploying a gastric balloon structure in a gastric cavity of a patient, comprising:

• determining one or more dimensions of the gastric cavity in a feeding state;
• selecting a respective fill volume for each chamber of a plurality of isolated chambers of the gastric balloon structure;
• introducing the gastric balloon structure to the gastric cavity;
• and
• after said introducing, at least partially filling each chamber of the plurality of isolated chambers of the gastric balloon structure with the respective volume of fluid via a valve system of the gastric balloon structure, wherein
• the plurality of isolated chambers are non-concentric and adjacent,
• at least partially filling each chamber of the plurality of isolated chambers comprises introducing fluid into the respective chamber via a respective valve structure of the valve system, and
• a collective volume of the plurality of isolated chambers remaining inflated after deflation of any single chamber of the plurality of isolated chambers prevents the gastric balloon structure from passing through the pyloric valve of the gastric cavity;
• wherein the gastric balloon structure, in its inflated state, is to form to a curved shape conforming to a natural three-dimensional kidney shape of the gastric cavity such that an outer surface of the gastric balloon structure aligns against greater and lesser curvatures of the gastric cavity.

A system for treating obesity, comprising:

• a means for conforming a flexible, space-filling structure to a natural kidney shape of a gastric cavity of a patient;
• a means for maintaining at least two isolated inflatable regions of the flexible, space-filling structure such that a collective volume of the at least two isolated inflatable regions remaining inflated after deflation of any single isolated inflatable region of the at least two isolated inflatable regions prevents the flexible, space-filling structure from passing through the pylorus of the patient;
• a means for introducing a fluid into each of the at least two isolated inflatable regions after positioning the flexible, space-filling structure within the gastric cavity, wherein the means for introducing, after introduction of the fluid, is removed from the gastric cavity and during treatment remains separated from said means for conforming;
• and
• a means for receiving the fluid into each region of the at least two isolated inflatable regions and for retaining the fluid in each region, wherein the fluid is received from the means for introducing the fluid.
