ABSTRACT:
A food intake-limiting device for peroral implantation in the stomach adjacent a gastroesophageal junction is disclosed. The device can have an inner basket nested in an outer basket, a proximal entry opening and a distal exit opening to limit a rate of efflux, mesh openings in the outer basket for protrusion of stomach lining into the outer basket, and a plurality of spikes mounted tangentially on the inner basket for transfixing the protruding stomach lining. The inner basket is rotatable with respect to the outer basket to effect the transfixation. Also disclosed are an implantation/extraction tool, and methods for implanting and removing the device in a patient in need of obesity treatment.
