摘要： An intragastric device for weight management is disclosed, comprising a capsule configured to be readily swallowed; an inflation magnet within the capsule configured to slideably engage the capsule and move along the longitudinal axis of the capsule during activation of the intragastric device by an external magnet; a first chamber configured to store a first chemical; a second chamber configured to store a second chemical; a partition having a through hole configured to physically separate the first chamber from the second chamber, a separator sealing the through hole before the activation and unseal the through hole to allow a chemical reaction between the first chemical and the second chemical during the activation; a balloon secured to the capsule and collapsed against an outer surface of the capsule before the activation; and an expandable volume defined at least partially by the balloon and the outer surface of the capsule, wherein the expandable volume configured to expand when the balloon is inflated by a gaseous product of the chemical reaction. The device may include a deflation magnet to deflate the balloon and a flexible membrane connected to the inflation magnet to allow passage of the gas out of the balloon over time.
