Abstract
Upon filling multiple inflatable chambers of a gastric balloon structure in a patient's stomach, the gastric balloon structure assumes a natural three-dimensional kidney shape of the gastric cavity. A flexible central spine may span a gap between two inflatable chambers and may include lumens for inflation of one or both chambers. The plurality of compartments, when in an inflated state, may form a cavity therebetween through which food may pass and may leave in a stomach a residual volume of 10 ml to 100 ml.
