ABSTRACT:
The anti-obesity dual stent includes a tubular outer structure within which is located a coaxial tubular inner structure. The outer structure is sized to fit within a duodenum in substantially coaxial relation therewith. The outer and inner structures communicate with the pylorus and papilla of Vater to provide conduits for the chyme and digestive fluid. Alternatively, the anti-obesity dual stent may include a tubular papilla-supplied structure which has a lateral orientation relative to a tubular pylorus-supplied structure. The papilla-supplied and pylorus-supplied structures each are sized to fit longitudinally within the duodenum. The pylorus-supplied and papilla-supplied structures communicate with the pylorus and papilla of Vater to provide conduits for the chyme and digestive fluid.
