Abstract

Method and apparatus for limiting absorption of food products in specific parts of the digestive system is presented. A gastrointestinal implant device is anchored in the stomach and extends beyond the ligament of Treitz. All food exiting the stomach is funneled through the device. The gastrointestinal device includes an anchor for anchoring the device to the stomach and a flexible sleeve. When implanted within the intestine, the sleeve can limit the absorption of nutrients, delay the mixing of chyme with digestive enzymes, altering hormonal triggers, providing negative feedback, and combinations thereof. The anchor is collapsible for endoscopic delivery and removal.

Dependent claims

A gastrointestinal implant device comprising:

a sleeve at least 12 inches in length, open at both ends, unsupported at its distal end, and adapted to extend within the intestine;
a collapsible sleeve anchor coupled to a proximal portion of the sleeve and adapted to anchor the sleeve within the digestive system;
and
bi-directional barbs extending from the exterior surface of the sleeve anchor, each barb comprising two tines directed in opposite directions from each other and outwardly from the anchor, wherein one tine is so oriented at an oblique angle as to prevent longitudinal movement of the device in a first direction and another tine is so oriented at an oblique angle as to prevent longitudinal movement of the device in a second direction substantially opposite to the first direction.
