What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12582540B2 for an intragastric device. The device is designed to be inserted into the gastric cavity to restrict its capacity and is based on the principle of neutral buoyancy. It comprises an inner core with a chamber and a valve for introducing pressurized fluid, and an outer covering with a cavity and a second valve for introducing a volume of fluid at a different pressure.

This patent grant is a routine administrative action by the USPTO and does not impose new regulatory obligations on regulated entities. It signifies the protection of intellectual property for a novel medical device. Compliance officers should note this as an update in the medical device landscape, particularly for companies involved in bariatric or gastrointestinal interventions.

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).
