Patent ID: 8636683

Claim:
A gastrointestinal implant device comprising: a first anchoring mechanism designed to be secured along a gastrointestinal tract and within a stomach; a second anchoring mechanism coupled to and spaced from the first anchoring mechanism, the second anchoring mechanism designed to be secured further along the gastrointestinal tract and beyond the stomach; a coupling mechanism attaching the first anchoring mechanism to the second anchoring mechanism, the coupling mechanism is configured to allow rotational movement of the second anchoring mechanism relative to the first anchoring mechanism following implantation of the gastrointestinal implant device, while limiting movement of the second anchoring mechanism along the gastrointestinal track away from the first anchoring mechanism; and a sleeve coupled to and positioned outside the second anchoring mechanism, the sleeve designed for placement into a small intestine and to minimize absorption of nutrients by a wall of the small intestine, wherein the second anchoring mechanism is a three dimensional array of struts having a spherical or a partially spherical shape and is configured to maintain a seal between the sleeve and the duodenal or intestinal wall to ensure that food from the stomach passes into the sleeve while minimizing leaking into the small intestine.
