Abstract
An apparatus for reducing obesity in human beings having an inflatable bag to which a flexible tube is attached. The bag is positioned in the stomach, usually by swallowing, and the tube extends up through the esophagus and out of a nasal cavity or out from the abdomen when a gastrostomy is performed. The bag is inflated by attachment of a supply of fluid to the end of the tube, and then the tube is closed so that the bag will maintain its inflated conditon. With a portion of the open cavity of the patient'"'"'s stomach occupied by the inflated bag, the patient will sense a feeling of being "filled-up" with only a small amount of food intake.

7. A method or reducing obesity in human beings by decreasing the desire for food which comprises:
-
placing an inflatable, elastomeric bag having a first, flexible tube attached thereto, into the stomach of the human being through the mouth cavity of the human being so that one end of the tube extends into the mouth cavity of the human being; inserting a second, flexible tube through the opening in one side of the human being'"'"'s nasal cavity in such a manner that one end is projected into the mouth cavity, and the other end of the second tube extends from the nose; connecting the one end of the first tube to the one end of the second tube so that a passageway is provided through the tubes from the other end of the second tube, outside the nasal cavity, to the interior of the bag; delivering an amount of a fluid through the other end of the second tube, from a supply, through said passageway for inflation of the bag; and sealing off the other end of the second tube so that the bag maintains its inflated condition. - View Dependent Claims (8, 9)

10. A method of reducing obesity in human beings by decreasing the desire for food which comprises:
-
placing an inflatable, elastomeric bag having a first, flexible tube attached thereto, into the stomach of the human being through the mouth cavity of the human being; performing a gastrostomy on the human being whereby an opening is made in the stomach wall and an adjacent opening is made in the human being'"'"'s abdomen; drawing out through both openings to a point of exit to the atmosphere on the human being'"'"'s abdomen one end of the tube so that a passageway is provided through the tube to the interior of the bag; delivering an amount of fluid through the one end of the tube, from a supply, through said passageway for inflation of the bag; and sealing off the one end of the tube so that the bag maintains its inflated condition, and alternately inflating and deflating the bag and having the human being eat orally by placing food in the mouth and swallowing. - View Dependent Claims (11)

12. An apparatus for reducing obesity in human beings by decreasing the desire for food which comprises:
-
an inflatable, elastomeric bag sized for positioning in the human being'"'"'s stomach, the bag of a substantially physiologically inert and nontoxic material, said bag having an inflatable body portion, a neck portion and only one bag opening, said one bag opening being in said neck portion; a first flexible tube having only one passageway, said tube having a first end connected to the opening in said neck portion of said bag and also having a second end, said tube being of a sufficient length between said first and second ends to extend from the neck portion of said bag up through a human being'"'"'s esophagus into the cavity of the human being'"'"'s mouth; a second flexible tube of smaller diameter than said first tube having only one passageway and of a sufficient length to extend from the opening of one of the human being'"'"'s nasal cavities to the cavity of the human being'"'"'s mouth, said tube having a first end and a second end, said first end being adapted to exit at said cavity of the mouth, said second end being adapted to extend from said opening of the nasal cavity both tubes being of a substantially, physiologically inert and nontoxic material; means for joining the second end of the first tube to the first end of the second tube in a sealed connection, thereby forming a passageway through the tubes from said opening of the nasal cavity to the interior of the bag; means for closing said second end of the second tube to prevent fluid within said bag from escaping to the atmosphere whereby upon opening of said means the fluid is allowed to escape to the atmosphere thereby deflating the bag.
