Patent ID: 8376981

Claim:
A device for diverting fluid from a duct in a wall of a small intestine, the device comprising: a support frame having a first cuff, a second cuff, a central portion and a passageway extending through the central portion, where the central portion has a reduced diameter relative to a diameter of the first or second cuffs and at least one opening in a side-wall of the central portion, wherein the first and second cuffs are expandable, the second cuff being configured to form a fluid tight seal against the wall of the small intestine distal to a duct opening and the first cuff being configured to form a fluid tight seal against the wall of the small intestine proximal to the duct opening such that the first and second cuffs in combination with an exterior wall of the central portion and a wall of the small intestine define a reservoir for receiving fluid from the duct; an elongate conduit coupled to the side-wall of the central portion where at least a portion of the conduit extends within the passageway, the conduit having a first end, a second end having an opening, and a side-wall having an opening, wherein the opening in the side-wall of the conduit is connected to the opening in the side-wall of the central portion such that fluid entering the opening in the side-wall of the central portion from the reservoir or directly from the duct passes through the opening in the side-wall of the conduit, the conduit being configured to advance fluid from the opening in the side-wall of the conduit to the second end of the conduit and, wherein a diameter of the elongate conduit is smaller than a diameter of the passageway such that foods and other digestive substances may pass through the passageway and past the conduit without entering the conduit; and a sheath disposed around the support frame, where a first end of the sheath is attached to a first cuff and a second end of the sheath is attached to a second cuff creating a gap between an exterior wall of the central portion and the sheath, the sheath having an opening for receiving fluid from the duct.
