Intragastric device

An intragastric device, insertable into a gastric cavity to restrict food intake capacity, comprising an ellipsoidal and flexible inner chamber, comprising:

• a first wall, curved and closed on itself, with an external face and an internal face, which perimetrically delimits a first hollow internal cavity;
• a first valve connecting the inside of the first cavity to the outside of the device;
• and
• a flexible outer covering, which at least partially surrounds and contains the chamber and which in turn comprises:
• a second wall, curved and closed on itself, with an external face, intended to face the internal walls of the gastric cavity, and an internal face that delimits perimetrically a second cavity that houses inside it the first wall and part of the first valve of the chamber, and
• a second valve connecting the inside of the second cavity to the outside of the intragastric device;
• wherein the first cavity houses a volume of pressurized fluid introduced into and extracted from through the first valve, and the second cavity houses a volume of pressurized fluid introduced into and extracted from through the second valve, wherein the fluid pressure of the pressurized fluid inside the second cavity is different from the fluid pressure of the pressurized fluid inside the first cavity;
• and
• wherein the first internal cavity of the chamber is made up of sectors connected to each other by means of narrowings.
