Intragastric device

Abstract

Intragastric device intended to be inserted into a gastric cavity to restrict its capacity. To contribute to optimal adaptation, its design is based on the principle of neutral buoyancy. The device comprises an inner core and an outer covering (2). The inner core consists of a closed chamber (1) and a first valve (4) connecting the inside of the chamber (1) to the outside, through which a pressurised fluid is introduced into the chamber (1). The outer covering (2) comprises a first cavity (5), in which the core is housed, and a second valve (7), through which a volume of fluid is introduced into the free space of the cavity not occupied by the chamber (1). This fluid in the first cavity (5) is at a different pressure to that of the fluid introduced into the chamber (1).
