PROBLEM TO BE SOLVED: To provide a device for a digestive organ which enables the smooth movement of an inflow object from the base end side of a cylinder part toward the distal end side by restricting the movement of the inflow object from the distal end side of the cylinder part to the base end side which can be generated in association with the motion of the digestive organ, thereby exerting sufficient effect for the treatment of diabetes and obesity.SOLUTION: A device 100 for a digestive organ comprises: a cylinder part 110 disposed in a digestive organ of a living body an indwelling part 120 for holding the cylinder part in the living body and a movement restriction part 200, which is arranged in the cylinder part and configured to be deformable following the motion of the digestive organ, for restricting an inflow object flowed into the cylinder part through a through hole to move to the base end side of the cylinder part due to the motion of the digestive organ.COPYRIGHT: (C)2015,JPO&INPIT【課題】消化器官の運動に伴って生じ得る筒部の先端側から基端側への流入物の移動を制限することにより、筒部の基端側から先端側へ向かう流入物の円滑な移動を可能にし、もって糖尿病や肥満の治療に対する十分な効果を発揮する消化器官用デバイスを提供する。【解決手段】消化器官用デバイス100は、生体の消化器官内に配置される筒部110と、筒部を生体内に保持する留置部120と、筒部に設けられ、消化器官の運動に追従して変形可能に構成されるとともに、貫通孔を介して筒部内に流入した流入物が消化器官の運動によって筒部の基端側へ移動することを制限する移動制限部200とを有している。【選択図】図1
