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 partition a stomach into a first portion and a second portion, and to provide a passage between the first and second portions of the stomach, the gastric band comprising:

a partitioning section comprising a distal end of the gastric band and configured to extend from a first end of the stomach towards a second end of the stomach opposite the first end, the partitioning section having a first arm extending a majority of a length of the 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 partition the stomach into the first and second portions; and

a passage-forming section comprising a proximal end of the gastric band, the passage-forming section configured to extend from the second end of the stomach towards the first end of the stomach, the passage-forming section configured to form the passage between the first and second portions of the stomach, the passage-forming section having first and second passage-forming arms extending substantially in a direction towards the partitioning section and at least partially spaced apart at a first location by a second distance greater than the first distance;

wherein the first and second passage-forming arms are continuous with each other and are both at least partially curved, the first passage-forming arm is continuous with the first arm of the partitioning section, and the second passage-forming arm is continuous with the second arm of the partitioning section,

wherein the first passage-forming arm is substantially collinear with the first arm of the partitioning section when viewed from at least one angle, and

wherein the second passage-forming arm is substantially collinear with the second arm of the partitioning section when viewed from at least one angle.

2. The gastric band of claim 1, wherein the first portion of the stomach is a food pouch and the second portion of the stomach is a fundic region.

3. The gastric band of claim 1, wherein the first and second arms of the partitioning section are parallel.

4. The gastric band of claim 1, further comprising apertures in at least one of the first or second arms of the partitioning section.

5. The gastric band of claim 1, wherein the first and second passage-forming arms are symmetrically disposed.

6. The gastric band of claim 1, further comprising a biasing section configured to bias at least the first and second arms of the partitioning section to form the first and second portions of the stomach.

7. The gastric band of claim 6, wherein the biasing section is further configured to bias the first and second passage-forming arms to form the passage between the first and second portions of the stomach.

8. The gastric band of claim 6, wherein the biasing section is disposed towards the distal end of the gastric band.

9. The gastric band of claim 6, wherein the biasing section is disposed towards the proximal end of the gastric band.

10. The gastric band of claim 6, wherein the biasing section comprises at least one of a hinge, bight portion, and magnetic coupler.

11. 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 partitioning section.

12. The gastric band of claim 1, further comprising an inflatable portion.

13. The gastric band of claim 12, wherein the inflatable portion comprises at least a portion of the partitioning section.

14. 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; and

a second section disposed at an end of the gastric band opposite the first section, the second section having a first arm substantially collinear with the first arm of the first section when viewed from at least one angle, and having a second arm substantially collinear with the second arm of the first section when viewed from at least one angle, the first and second arms of the second section being at least partially spaced from one another a second distance configured to form a passage between the first compartment of the stomach and the second compartment of the stomach, wherein the second distance is greater than the first distance;

wherein the first and second arms of the second section are continuous with each other and are both at least partially curved, 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.

15. The gastric band of claim 14, wherein the first compartment of the stomach comprises a food pouch and the second compartment of the stomach comprises a fundic region.

16. The gastric band of claim 14, wherein the passage formed by the second section provides a passage from the second compartment into an antrum of the stomach.

17. The gastric band of claim 14, further comprising 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.

18. The gastric band of claim 14, further comprising a biasing section configured to bias at least the first and second arms of the second section to form the passage between the first compartment of the stomach and the second compartment of the stomach.

19. The gastric band of claim 14, further comprising an inflatable portion.

20. The gastric band of claim 19, wherein the inflatable portion comprises at least a portion of the first section.
