Abstract

The present invention provides a surgical method for reducing the food intake of a patient by dissecting the lower part of the Esophagus of a patient, applying a band to form a loop around the lower part of the Esophagus and displacing an upper part of the stomach through the loop, thereby forming a small pouch above the band wherein the final position of the band is above the Bursa Omentalis.

Claims

1. A surgical method for reducing the food intake of a patient, comprising,

dissecting the lower part of the Esophagus of a patient,

applying a band to form a loop around the Esophagus,

displacing an upper part of the stomach through said loop,

thereby forming a small pouch above said band connected to the Esophagus, and

suturing said upper part to the stomach wall, thereby tunnelating said band.

2. A surgical method in accordance with claim 1, further comprising using a band having a wider portion than the rest of said band, said wider portion being disposed against the lower part of the Esophagus.

3. A surgical method in accordance with claim 1, further comprising the use of a band having an essentially nonexpansible outer wall and an expansible inner wall, said outer and inner walls being joined together to form a closed expansible cavity connected to said outer wall, a conduit being provided, one end of which opens into said cavity, the other end of which opens into an injection port.

4. A surgical method in accordance with claim 3, wherein said opening of said band loop is adjusted, or narrowed as a function of an expansion of said pouch.

5. A surgical method in accordance with claim 3 wherein said injection port is implanted subcutaneously preferably against the lower part of Sternum.

6. A surgical method in accordance with claim 1, wherein said pouch in the unexpanded condition has a volume of about 7 ml.

7. A surgical method comprising the steps of:

dissecting the lower part of the Esophagus of a patient;

applying a band to form a loop around the lower part of the Esophagus; and

displacing an upper part of the stomach through said loop, thereby forming a small pouch above said band;

wherein the fmal position of said band is above the Bursa Omentalis.

8. A surgical method comprising the steps of:

dissecting the lower part of the Esophagus of a patient in such a way that a portion of the posterior surface of the stomach remains adherent to the underlying tissue;

applying a band to for a loop around the lower part of the Esophagus; and

displacing an upper part of the stomach through said loop, thereby forming a small pouch above said band;

wherein the final position of said band is in the area where the lower part of the Esophagus and the upper part of the stomach is adherent to the underlying tissue.

9. A surgical method for reducing the food intake of a patient, comprising

dissecting the lower part of the Esophagus of a patient,

applying a band to form a loop around the Esophagus,

displacing an upper part of the stomach through said loop,

thereby forming a small pouch above said band connected to the Esophagus.
