(72) Inventor(s) Demarais, Denise Marie (74) Agent/Attorney Shelston IP, Level 21 60 Margaret Street, Sydney NSW, 2000 -1- Methods and devices for simulating a gastric bypass and reducing the volume of the stomach involve placing a tubular liner along the lesser curve of the stomach cavity. Also, methods and devices for slowing gastric emptying involve placing valves within the stomach cavity near the gastro-intestinal junction and/or the pylorus. These methods and devices may prevent a patient from drinking and eating large volumes at one time and from eating slowly all day. 1. A system for affecting satiety, comprising:
an element having a cylindrical body with an inlet end and an outlet end for placement near the gastroesophageal junction; a fixation device having a working portion adapted for transoral placement within a stomach cavity; wherein the working portion of the fixation device acquires a fold of tissue fi'om the lesser curve of the stomach and at least a portion of the cylindrical body of the element and fixes the cylindrical body of the element within the fold of tissue fi'om the lesser curve of the stomach. 2. The system of claim 1, wherein the element includes a liner formed of PET, nylon, polyester, PTFE, polyethylene, polystrene, polyurethane or silicone. 3. The system of claim 1, wherein the element includes a balloon liner. 4. The system of claim 1, wherein the element includes a balloon device. 5. The system of claim 1, wherein the element includes a valve. 6. The system of claim 1, wherein the element includes a tube and an isolation element. 7. The system of claim 1, wherein the element includes a gastric device. 8. The system of claim l, wherein the working portion of the fixation device includes a cartridge member in apposition with an anvil member, and the cartridge member and anvil member clamp together to fix the cylinder body of the element within the fold of tissue from the lesser curve of the stomach. 9. The system of claim 8, wherein the cartridge member holds and dispenses a plurality of staples. 10. The system of claim 8, wherein the cartridge member holds and dispenses a plurality o f anchors. 11. The system of claim 8, wherein the fixation device includes a flexible shaft with a proximal end and a distal end, and a handle connected at the proximal end and the working portion connected at the distal end. 12. The system of claim 2, further comprising a sheath, wherein the sheath holds the liner at the working portion when the fixation device is placed within the stomach cavity. 13. A system for affecting satiety, comprising:
an element having a cylindrical body with an inlet end and an outlet end for placement near the gastroesophageal junction; a tissue acquisition and fixation device having a working portion adapted for transoral placement within a stomach cavity; wherein the working portion of the tissue acquisition and fixation device acquires a single fold of tissue from the stomach and at least a portion of the cylindrical body of the element and fixes the cylindrical body of the element within the fold of tissue from the stomach. 14. The system of claim 13, wherein the working portion of the tissue acquisition and fixation device acquires a dual fold of tissue fi'om the stomach and fixes the cylindrical body of the element within the dual fold of tissue. 15. The system of claim 14, wherein the cylindrical body is a liner fixed to the dual fold of tissue with a plurality of staples. 16. A system for affecting satiety substantially as herein described with reference to any one of the embodiments of the invention illustrated in the accompanying drawings and/or examples.
