Abstract:
1. An anti-obesity diverter structure comprising: a self-expanding laminate structure comprising a tubular structure having proximal and distal ends, said laminate structure having a pair of lateral edges each of which extends between said proximal and distal ends, said lateral edges defining a width of said laminate structure, said laminate structure being sized to fit longitudinally within a duodenum of a human being wherein said laminate structure is a stent; and a retainer structure connected to said laminate structure, said laminate structure being impervious or semi-permeable to chyme and digestive fluid wherein the duodenum of a human being has a lumen which has an outer periphery defined by the inner surface of the duodenum, wherein said width of said laminate structure provides for a bisection of the lumen of the duodenum by said laminate structure, wherein the lumen of the duodenum of a human being has a cross section which is substantially circular when said laminate structure is not located therein, said width of said laminate structure being sufficiently large such that the cross section of the lumen of the duodenum is substantially elliptical when said laminate structure is secured therein.
