- 3. A method for treating obesity in humans comprising the steps of assembling a deflated stomach balloon with an insufflation tube releasably attached thereto inside a standard stomach tube, the balloon having a manufactured shape and significant resistance to over-inflation, thereafter introducing the stomach tube through the mouth and into the stomach, urging the balloon out of the stomach tube and into the stomach, inflating the balloon through the insufflation tube with a given amount of fluid to increase the volume thereof to its manufactured shape, releasing the insufflation tube from the inflated balloon thereby enabling the inflated balloon to freely float within the stomach, and then removing the stomach tube and the insufflation tube from the stomach and out through the mouth whereby the inflated balloon is unattached and free to float within the stomach.

7. An assembly comprising a stomach tube having a longitudinal slit at one end thereof, a deflated stomach balloon inside the tube at the same end as the longitudinal slit, insufflation means releasably attached to the balloon and extending through the stomach tube, and drawstring means releasably closing the end of the stomach tube at the slit whereby upon removal of the drawstring means and inflation of the balloon the balloon is easily separated from the stomach tube as the tube spreads apart at the slit.
