Abstract

Devices and methods for modifying stomach volume include the formation of intragastric slots for wrapping one or more portions of the fundus therethrough with minimal interference with nerves and vasculature flow. Intragastric space occupying devices expand with environmental changes brought about by natural conditions inherent to the digestive cycle such as with changes in pH. Extragastric volume occupying balloons are placed into folded stomach sections. The balloons are fluidly coupled to external gastric filling devices. In yet another set of embodiments, methods and devices provide adjustable gastric volume reduction fundal wraps. In one embodiment, a device is placed in the fundus for Nissen fundoplication and permits postoperative adjustment to reach desired weight loss. Intragastric and extragastric balloons are optionally incorporated.

Claims

1. A method of reducing contact of ingested food content within a patient with ghrelin producing cells within a stomach cavity, the method comprising:

a. creating a sealed enclosed aperture along a stomach of a patient; and

b. implanting a space occupying device adjacent said aperture on a side closer to a greater curvature of the stomach and passing a portion of the greater curvature through the aperture exterior of a gastric cavity and securing it therethrough to form a sleeve.

2. The method of claim 1 wherein said step of implanting said space occupying device comprises implanting said device within said stomach.

3. The method of claim 1 wherein said step of implanting said space occupying device comprises securing said device along an exterior of said stomach.

4. The method of claim 1 further including the step of adjusting the size of said implant after implantation.

5. The method of claim 1 wherein said space occupying device expands according to environmental changes.

6. The method of claim 1 wherein said space occupying device expands according to changes in pH.

7. The method of claim 1 wherein said space occupying device comprises a balloon.

8. The method of claim 1 wherein said space occupying device is placed into a folded stomach section.

9. The method of claim 1 wherein said space occupying device comprises a balloon placed in an intragastric location.

10. The method of claim 1 wherein said space occupying device comprises a balloon placed in the fundus of said stomach.

11. The method of claim 1 wherein said space occupying device is fluidly coupled to an external gastric filling device.

12. The method of claim 1 wherein said space occupying device is used in combination with a gastric volume reduction fundal wrap.

13. The method of claim 1 wherein a gastric band is placed around said sleeve.

14. The method of claim 1 wherein said space occupying device is capable of being adjusted postoperatively.

15. The method of claim 1 wherein mucosa-to mucosa contact is maintained in the portion of the greater curvature through the aperture exterior of a gastric cavity such that ingested substances pass primarily through said sleeve.

16. A method of providing a benefit to a patient, the method comprising the step of surgically reducing stomach volume such that nutrient flow is rerouted away from the fundus and greater curvature of a stomach of the patient.

17. The method of claim 16 wherein said act of surgically reducing stomach volume comprises wrapping a portion of said stomach through a slot in said stomach and around said stomach.

18. The method of claim 16 wherein said method is carried out during a full or partial fundoplication procedure.

19. The method of claim 16 wherein said benefit is selected from reducing hunger, promoting learning, improving memory functions, treating depression, promoting sleep, and combinations thereof.

20. A method of providing a benefit to a patient, the method comprising the steps of:

a. separating a patients stomach into a sleeve portion comprising the lesser curvature of the stomach and a wrap portion comprising the greater curvature and fundus of the stomach; and

b. positioning said wrap portion around said sleeve portion such that said wrap portion functions as a self-adjusting gastric band around said sleeve portion.
