Abstract

An adjustable band or clamp or non-adjustable clamp is placed about the greater curvature of the stomach in a vertical orientation. The band or clamp completely compartmentalizes the stomach between a small vertical pouch and the fundus and body of the stomach. The fundus and body of the stomach are excluded from nutrients and are separated from a long narrow channel where the food travels. A small passage at the level of the antrum allows gastric juices to empty from the fundus and body of the stomach. The clamp may be applied during open surgery in laproscopic surgery or using a single port technique, or through any natural orifice in NOTES (Natural Orifice Transluminal Endoscopic surgery) or using a hybrid surgical technique.

Claims

1. A gastric band configured to extend from a top end of a stomach to a bottom end of the stomach adjacent an antrum of the stomach to divide the stomach into a food pouch and fundic region and to provide a passage between the food pouch and fundic region, the passage formed at the bottom end of the stomach adjacent the antrum of the stomach, the gastric band comprising:

a compartment-forming section comprising a distal end of the gastric band configured to extend from the top end of the stomach towards the bottom end of the stomach, the compartment-forming section having a first arm extending a majority of a length of said gastric band and a second arm extending a majority of the length of the gastric band and spaced apart from the first arm by a first distance configured to form the food pouch and the fundic region;

a passage-forming section comprising a proximal end of the gastric band, the passage-forming section configured to extend from the bottom end of the stomach adjacent the antrum of the stomach towards the top end of the stomach, the passage-forming section configured to be positioned at the bottom end of the stomach adjacent the antrum of the stomach and configured to form the passage between the food pouch and the fundic region, the passage-forming section having a first arm extending in a direction towards and substantially collinear with the compartment-forming section and a second arm extending in a direction towards and substantially collinear with the compartment-forming section and at least partially spaced apart at a first portion by a second distance, which is greater than the first distance; and

a biasing section configured to bias at least the first and second arms of the compartment-forming section to form the food pouch and the fundic region,

wherein the first and second arms of the passage-forming section are arcuate and continuous, the first arm of the passage-forming section is continuous with the first arm of the compartment-forming section, and the second arm of the passage-forming section is continuous with the second arm of the compartment-forming section.

2. The gastric band of claim 1, wherein the first and second arms of the compartment-forming section are parallel.

3. The gastric band of claim 1, further comprising apertures in at least one of the first or second arms of the compartment-forming section.

4. The gastric band of claim 1, wherein at least one of the compartment-forming section and passage-forming section form a closed loop.

5. The gastric band of claim 1, wherein at least one of the compartment-forming section and passage-forming section form a U-shape.

6. The gastric band of claim 1, wherein said two arms of the passage-forming section at least partially spaced apart by said second distance are symmetrically disposed.

7. The gastric band of claim 1, wherein said compartment-forming section is substantially continuous.

8. The gastric band of claim 1, wherein the biasing section is further configured to bias the first and second arms of the passage-forming section to form the passage at the bottom portion of the stomach adjacent the antrum of the stomach and between the food pouch and the fundic region.

9. The gastric band of claim 1, wherein the biasing section is disposed towards the distal end of the gastric band.

10. The gastric band of claim 1, wherein the biasing section is disposed towards the proximal end of the gastric band.

11. The gastric band of claim 1, wherein the biasing section comprises at least one of a hinge, bight portion, and magnetic coupler.

12. The gastric band of claim 1, wherein the gastric band further comprises at least one strap coupled to the first and second arms of the compartment-forming section.

13. A gastric band, comprising:

a first section having first and second arms spaced from one another a first distance configured to close walls of a stomach together to form a first compartment of the stomach and a second compartment of the stomach, said first section extending a majority of a length of said gastric band;

a second section disposed at an end of the gastric band opposite the first section and configured to be positioned at a bottom portion of the stomach adjacent an antrum of the stomach, the second section having first and second arms substantially collinear with the first and second arms of the first section and at least partially spaced from one another a second distance configured to form a passage at the bottom portion of the stomach adjacent the antrum of the stomach and between the first compartment and second compartment, wherein the second distance is greater than the first distance; and

a biasing section configured to bias at least the first and second arms of the first section to form the first and second compartments of the stomach,

wherein the first and second arms of the second section are arcuate and continuous, the first arm of the second section is continuous with the first arm of the first section, and the second arm of the second section is continuous with the second arm of the first section.

14. The gastric band of claim 13, wherein, the first and second arms of the first section are inflatable.

15. The gastric band of claim 13, wherein said first section is substantially continuous.

16. The gastric band of claim 13, wherein the first compartment of the stomach comprises a food pouch and the second compartment of the stomach comprises a fundic region.

17. The gastric band of claim 13, wherein the passage formed by the second section provides a passage from the second compartment into the antrum of the stomach.

18. The gastric band of claim 13, wherein the biasing section is further configured to bias at least the first and second arms of the second section to form the passage at the bottom portion of the stomach adjacent the antrum of the stomach and between the first compartment and second compartment.

19. The gastric band of claim 13, wherein the biasing section comprises at least one of a hinge, bight portion, and magnetic coupler.
