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 be positioned on a stomach to partition the 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 first end of the gastric band having a first arm with a bent end and a first elongate member extending a majority of a length of the gastric band and a second arm with a bent end and a second elongate member extending a majority of the length of the gastric band and spaced apart a first distance from the first elongate member;

a passage-forming section comprising a second end of the gastric band, and having a curved member joining together the bent ends of the first and second arm of the partitioning section and spacing the bent ends apart by a second distance greater than the first distance; and

an inflatable portion comprising at least a portion of at least one of the partitioning section and the passage-forming section.

2. The gastric band of claim 1, wherein the curved member is one-piece from the joining of the bent end of the first arm to the joining of the bent end of the second arm.

3. The gastric band of claim 1, wherein the first and second arms of the partitioning section are in a parallel relation to one another.

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

5. The gastric band of claim 1, wherein the inflatable portion comprises at least a portion of the partitioning section.

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 portions 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. A gastric band, comprising:

a first section having first and second arms spaced from one another a first distance when positioned on a stomach and configured to close walls of the 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, the second section having first and second portions, the first portion coupled with the first arm of the first section at a bent end of the first arm and the second portion coupled with the second arm of the first section at a bent end of the second arm, and the first and second portions at least partially spaced from one another a second distance at the bent ends greater than the first distance, the second section configured to form a passage between the first compartment of the stomach and the second compartment of the stomach, wherein the second section is curved along its entire length, positioning the first and second arms opposite the second section and cantilevering from the second section; and

an inflatable portion, wherein the inflatable portion is at least a portion of at least one of the first section and the second section.

13. The gastric band of claim 12, wherein the first compartment of the stomach comprises a food pouch and the second compartment of the stomach comprises a fundic region.

14. The gastric band of claim 12, wherein the passage formed by the second section provides a passage from the second compartment into an antrum of the stomach.

15. The gastric band of claim 12, 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.

16. The gastric band of claim 12, wherein the second section serves as a biasing section configured to bias at least the first and second arms of the first section.

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

18. A gastric band 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;

a passage-forming section comprising a curved proximal end of the gastric band;

wherein the partitioning section comprises;

a first arm extending a majority of a length of the gastric band; and

a second arm extending the majority of the length of the gastric band,

wherein the second arm is spaced apart from the first arm by a first distance to partition the stomach into the first and second portions;

wherein the passage-forming section comprises;

a caudal-most curved portion extending toward the first arm and the second arm of the partitioning section,

a first passage-forming portion,

wherein the first passage-forming portion is at least partially curved,

wherein the first passage-forming portion is adjacent to the first arm of the partitioning section, and

wherein the first passage-forming portion extends substantially in a cranial direction towards the partitioning section;

a second passage-forming portion,

wherein the second passage-forming portion is at least partially curved,

wherein the second passage-forming portion is adjacent to the second arm of the partitioning section,

wherein the second passage-forming portion is adjacent to the first passage-forming portion, and

wherein the second passage-forming portion extends substantially in the cranial direction towards the partitioning section;

wherein the first passage-forming portion and the second passage forming portion are both united to the caudal-most curved portion;

wherein the first passage-forming portion and the second passage-forming portion are at least partially spaced apart at a location by a second distance,

wherein the second distance is greater than the first distance, and

wherein no portion of the gastric band crosses a tangent line that is tangent to the caudal-most point on the caudal-most curved portion.

19. A gastric band configured to be positioned on a stomach to partition the 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 at least a portion of which is inflatable, the partitioning section, comprising a first end of the gastric band having a first arm with a bent end and a first elongate member extending a majority of a length of the gastric band and a second arm with a bent end and a second elongate member extending a majority of the length of the gastric band and spaced apart a first distance from the first elongate member; and

a passage-forming section comprising a second end of the gastric band, and having a curved member joining together the bent ends of the first and second arm of the partitioning section and spacing the bent ends apart by a second distance greater than the first distance.
