The object of the present patent is characterized by being a brand-new device which was developed to control the esophageal flow it is made of biosynthetic material based on the natural latex extracted from the rubber tree Hevea brasiliensis, to be applied in the esophagus in order to control or limit the speed and amount of food intake and, thus, to provide weight loss. It preserves all digestive system functions, decreases food intake with the reduction of the esophagus lumen and, in turn, decreases the organ emptying, thus controlling the speed and amount of food intake.The “ESOPHAGEAL FLOW CONTROLLER”, to be used together with a technique for controlling and treating obesity, to control the volume and the speed of the food intake, stimulate a higher individuals chewing rate, thus decreasing the amount of food intake being adjustable to the esophagus lumen and to control the esophageal flow and the ESOPHAGEAL FLOW CONTROLLER being provided with a flexible and inflatable external part of a conductor duct with a fixed diameter, with a valve to let air in and with a flexible wire that enables its setting and removal, made of biosynthetic material, specifically but not limited to the natural latex extracted from the rubber tree Hevea brasiliensis and be constituted by the whole EFC set (1), external tube (2), internal tube (3), surgical wire (4), valve (5), scalp (6), transversal grooves (7), suction cups (8) and a radiographic indicator (9).
