Abstract: A non-inflated balloon with a valve is attached to the end of a thin flexible tube which is inserted through the patient's mouth and esophagus into their stomach. At this point the balloon is inflated with water to the desired size to fill up space in the patient's stomach. The tube is then detached from the balloon and removed, while a valve insures the balloon remains inflated to the existing size. The balloon remains alone and inflated in the patient's stomach. It takes up space in the stomach which reduces a patient's desire and ability to overeat. When the balloon needs to be removed another tube is inserted which has a claw to grab the balloon and puncture it. This deflates it and allows for it to be dragged out.
