Abstract: The present invention relates to an orally administrable intragastric balloon encapsulated so that, once it is in the stomach, the capsules dissolves and increases its volume thanks to the presence, inside thereof, of a superabsorbent edible polymer able of absorbing the water contained in the stomach.

Abstract: An expandable intragastric device, configured for being positioned into the stomach by an endoscopic procedure is provided. The device is capable of assuming a minimum-encumbrance configuration for delivery into the stomach and an expanded configuration for use in situ. The device also includes a balloon structure, which is capable of assuming a deflated configuration for delivery into the stomach and an inflated configuration for occupying a part of the stomach inner space. The overall configuration of the device is such that, once it is delivered in the stomach, food passes into the inner lumen of the supporting tubular body and into the intestine.
