1. A gastric device, comprising:
- an inflatable balloon, wherein the inflatable balloon is sized to make contact with a portion of a wall of a stomach of a human patient when the balloon is in an inflated state such that an outer surface of the balloon is configured to contact an inner surface of the wall;
a fillant delivery tube extending through the inflatable balloon, wherein a proximal outer surface of the fillant delivery tube is directly connected to a first portion of the inflatable balloon and a distal outer surface of the fillant delivery tube is directly connected to a second portion of the inflatable balloon spaced apart from the first portion; and
a control module for automatically inflating the balloon in the stomach with a biocompatible fillant,wherein the gastric device is configured to be inflated to a predetermined size with a predetermined volume of the biocompatible fillant.

Abstract
A medical system for the treatment of morbid obesity comprising an inflatable balloon implanted in a gastric cavity, a percutaneous fillant delivery tube and a control module connected to the tube for regulating the inflation and deflation of the balloon. The balloon may be individually contoured and inflated to occupy a large volume of the gastric cavity to provide a feeling of satiety. The balloon may also be deflated to give the gastric cavity lining a rest during less critical time.
