A device (10) for treatment of obesity of a patient comprises an annular element (12) having a relatively large outer boundary and a relatively small inner boundary, and an elongated flexible tube (14) extending from the relatively small inner boundary of the annular element to a distal end. The relatively large outer boundary is adapted to be attached to an inner wall of a stomach (100) of a patient, such that the annular element divides the stomach (100) into two chambers, an esophagus-end chamber close to an esophagus of the patient, and a pylorus-end chamber close to a pylorus of the patient. The invention also provides a method for treatment of obesity of a patient which includes inserting an annular element having a relatively large outer boundary and a relatively small inner boundary into a stomach of the patient, and attaching the relatively large outer boundary of the annular element to an inner circumference of the stomach of the patient.

L'invention concerne un dispositif (10) de traitement de l'obésité dont souffre un patient comprenant un élément annulaire (12) présentant un pourtour externe relativement ample et un pourtour interne relativement petit, et un tube flexible allongé (14) s'étendant depuis le pourtour interne relativement petit de l'élément annulaire vers une extrémité distale. Le pourtour externe relativement ample est apte à être fixé à une paroi interne de l'estomac (100) d'un patient, de manière que l'élément annulaire divise l'estomac (100) en deux chambres, une chambre à extrémité d'oesophage à proximité de l'oesophage du patient et une chambre à extrémité de pylore à proximité du pylore du patient. L'invention concerne également une méthode de traitement de l'obésité dont souffre un patient consistant à insérer un élément annulaire présentant un pourtour externe relativement ample et un pourtour interne relativement petit dans l'estomac du patient, puis à fixer le pourtour externe relativement ample de l'élément annulaire sur la circonférence interne de l'estomac du patient.
