Abstract:
1. A duodenal absorption barrier for use in limiting absorption of food in the small intestine of a human subject, comprising: an elongate polymeric sleeve at least 20 cm in length and extending between proximal and distal open ends, said sleeve having an exterior duodenum-contacting surface adapted for contacting the surrounding wall of the subject's duodenum, barbs or scales disposed on said exterior surface of the sleeve, and disposed entirely within the sleeve, a self-expandable wire structure adapted, in its expanded form, and with the duodenal absorption barrier positioned entirely within the small intestine of the subject, to exert an outward pressure of the exterior surface of the sleeve against the surrounding walls of the duodenum, thereby pressing the barbs or scales disposed on the exterior surface against the surrounding duodenal walls, to anchor the entire duodenal absorption barrier within the duodenum, where the sleeve acts as an absorption barrier within the duodenum.
