Inflatable gastric device for treating obesity

The method of treating extreme obesity in a patient comprising the steps of

• forming an incision in the abdomen of an obese patient;
• surgically implanting an inflatable balloon in the abdominal cavity of the patient adjacent to the stomach, said balloon having a filling tube the distal end of which is sealingly attached in communication with a hollow spheroidal adjusting port of self-sealing elastomeric material;
• suturing the adjusting port subcutaneously to the anterior wall of the fascia of the patient adjacent to the incision;
• closing the incision over the adjusting port and subsequently locating the adjusting port by palpation;
• and
• inserting a hypodermic needle through the skin of the patient into the adjusting port and introducing a fluid under pressure into the port for passage through the filling tube into the balloon to expand the balloon to distend the upper abdomen and produce a sense of satiety, thereby reducing the patient's desire to ingest food, and to compress the stomach, thereby reducing its capacity.
