Abstract
The intra-gastric weight loss system apparatus and method of the present invention includes an intra-gastric elastomeric rubber balloon with self-sealing fill valve, to be placed and retrieved without surgery. As a benign space-occupying device, it will decrease gastric capacity to the point that saiety (the feeling of fullness) will occur after very little food has been consumed. Thus, the advantages of gastric and intestinal by-pass surgery will be realized, without surgery and the many resulting complications thereof. The elastomeric balloon is inflated with a liquid, preferably a saline solution containing an X-ray contrast media. The balloon is placed in a person's stomach by passing a naso-gastric tube through the mouth. The N-G tube has a previously placed nylon pull string through the lumen and back up the exterior. After this, a metal stylette is run down the lumen to very near the end of the N-G tube. The rolled up balloon with fill tube attached is inserted into a...

What is claimed is:
1. Apparatus for use in achieving a loss of weight in an overweight person comprising:
- an inflatable device;
- means for placing said device within the stomach of the person without surgery;
- additional means for inflating said device with liquid after it has been placed in the person's stomach;
- further means for allowing both said placing means and said inflating means to be completely removed from the person so as to leave the inflated device floating in the person's stomach; and said further means including
- a pull string having a rollable finger cot attached at one end, and a releasable, self-closing fill valve as part of the inflatable device.
2. Apparatus as set forth in claim 1, wherein said releasable, self-closing fill valve receives one end of a flexible fill tube prior to the device being rolled up and associated with the extended finger cot for placing of the inflatable device in the person's stomach, said fill tube being connected to liquid supply means so that the inflatable device can be inflated with liquid after it has been placed in the person's stomach, and such inflation in turn effecting rolling up and disengagement of said finger cot from the device.
3. The method of placing a gastric cavity filling device within an obese person's gastric cavity without any surgery, comprising the steps of:
- providing an inflatable device in deflated form;
- attaching a fill tube to the inflatable device;
- inserting a hollow tube containing a string therethrough into the person's mouth, esophagus and gastric cavity;
- releasably attaching the deflated device with fill tube attached to one end of the string;
- pulling the other end of the string to pull the deflated device into the person's gastric cavity;
- inflating the deflated device through the fill tube and after suitable inflation of the device;
- removing all the placing apparatus so that the inflated device remains free-floating in the person's gastric cavity without any attachments thereto.
4. The method of claim 3, with the further steps of:
- inserting a stiffener member into the hollow tube containing the string therethrough prior to the step of pulling the string.
5. The method of claim 4, with the additional step of using liquid containing an X-ray opaque substance therein for inflating the device.
