An apparatus is provided for reducing the available volume of the human stomach whereby a loss of weight of an overweight patient can be obtained. The said apparatus is adapted for introducing an expandable foreign member through the mouth and the gullet for freely detached positioning in the human stomach. The apparatus is characterized by a combination of an elongated introducing member (1, 2, 5, 7) which can be positioned stretching through the mouth and the gullet having a first end projecting from the mouth and a second end projecting into the stomach, and an acid-resistant hollow foreign member (4) having a uniform thickness. The said introducing member comprises an elastic introducing tube (2) which at its first end is provided with a means (9) for supplying pressurized gas, air and/or liquid for expanding the said member, and which at its second end is provided with a withdrawable packing member (7) being positioned in a one-way valve member (3) which constitutes an integral part of the foreign member (4). The said introducing tube (2) is encased within an outer elastic tube (1) which connects the lower end of the means for supplying air, gas and/or liquid with the upper end of the valve member, said outer tube acting as a holder-on on the edge (6) of the said valve member (3). <IMAGE> |
