<P>PROBLEM TO BE SOLVED: To provide a device that employs an inhibitory sleeve within digestive canal so as to limit food absorption in specific portions of the digestive canal and give a morbidly obese patient a negative feedback for improving an eating habit. <P>SOLUTION: A gastrointestinal implant device includes a flexible sleeve 202 composed of a thin and flexible material and unsupported at distal end so that it opens at both ends thereof, extends into the intestinum, limits absorption of nutrients within the intestinum, and can shrinkable in small capacity within the intestinum and a self-expandable and shrinkable anchor 208 connected to a proximal end of the sleeve 202. The anchor 208 has a needle-shaped projection 210 with a structure suitable for insertion into muscle issues and arranged in a direction suitable for the insertion into the muscle issues when the anchor 208 extending from its outer surface is extended and anchors the proximal end of the sleeve 202 within the digestive canal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
