Expanding or foaming adhesives are used to reduce the stomach volume to
reduce the caloric intake and weight of a patient. A web structure is
attached inside the stomach and an expanding or foaming adhesive is
applied to the web structure. The expanding or foaming adhesive attaches
to the web structure and to the stomach to partition the stomach. The
partition barrier divides the stomach volume into a reduced volume
available for food storage and an empty volume that the food cannot
enter. The reduced volume enables the patient to feel full faster and
reduce caloric intake. A passageway can be provided between the two
volumes near the base of the stomach to allow food or fluids to exit from
the empty volume.
