    摘要： The present invention provides an intragastric volume-occupying device system, comprising a capsule configured to be swallowable by normal peristalsis and to degrade in a gastric environment. The system further comprises a volume-occupying component compacted and contained within the capsule, the volume-occupying component comprises a composite wall defining an outer surface and an interior cavity with an inner surface, a self-sealing valve system including a septum, and a deflation component including an erodible portion, a moisture absorbing expandable portion and an inlet port in fluid communication with the interior cavity. The system further comprises a catheter coupled to the valve system, the catheter comprising: a lumen in fluid communication with the interior cavity of the volume-occupying component, wherein the lumen is configured for filling the balloon interior cavity with an inflation fluid.

    摘要： The present invention provides a device comprising an intragastric balloon, comprising: a polymeric wall; a valve system; a casing; a sealing member; and a deflation component. The casing has one or more vent pathways, and the sealing member is positioned to block the one or more vent pathways when in place. The deflation component is situated in the casing and behind the retaining structure. The deflation component is configured, in use, to expand upon exposure to moisture inside of the balloon via the one or more vent pathways, thereby pushing the retaining structure and thus the sealing member linearly past the casing to open the one or more vent pathways so as to provide fluid communication between an in vivo gastric environment and a lumen of the balloon.
