    摘要: Devices and methods for treating obesity are provided. More particularly, intragastric devices and methods of fabricating, deploying, inflating, monitoring, and retrieving the same are provided. The intragastric devices include an intragastric balloon comprising an initial fill gas comprising an inert gas and CO2, a valve system, and a polymeric wall having, under conditions of an in vivo gastric environment, a permeability to CO2 of more than 10 cc/m2/day, such that a rate and an amount of diffusion of CO2 from the in vivo gastric environment into a lumen of the balloon through the polymeric wall is controlled, at least in part, by a concentration of the inert gas and a concentration of CO2 in the initial fill gas, wherein the concentration of CO2 in the initial fill gas is similar to gastric pCO2.
