Abstract

Aspects of this invention disclose devices and methods for attachment of a gastrointestinal sleeve. In some embodiments, the attachment device comprises a flexible cuff, a gastrointestinal sleeve interface, and a gastrointestinal sleeve. Some aspects of the invention contemplate the use of T-tags for attachment of the cuff to tissue. In some aspects of the invention, attachment of the sleeve to the cuff is achieved using various fasteners.

Claims

1. A method of attaching a gastrointestinal device within the gastrointestinal tract of a patient, comprising the steps of:

providing a device with a first attachment structure configured to attach the device to tissue;

extending a suture through a tissue plication to form a loop around the tissue plication;

extending a first end of the suture through the first attachment structure; and

guiding the device from the first end of the suture to the tissue plication.

2. The method of claim 1, further comprising providing a first anchor attached to the at least one of the first and a second end of the suture.

3. The method of claim 2, further comprising pulling on the other of the first and second end of the suture, such that the first anchor attaches the device to the tissue plication.

4. The method of claim 1, further comprising extending a second end of the suture through a second attachment structure in the device, wherein the second attachment structure is configured to receive the tissue plication, the plication positioned between the first and the second attachment structures.

5. The method of claim 4, further comprising providing a first anchor operably attached to at least one of the first and the second end of the suture.

6. The method of claim 5, further comprising pulling on the other of the first and second end of the suture, such that the first anchor attaches the device to the tissue plication.

7. The method of claim 6, further comprising providing a second anchor slidably attached to the other of the first and second end of the suture.

8. The method of claim 7, further comprising sliding the second anchor from the other of the first and second end of the suture to the tissue plication such that the tissue plication is anchored between the first and the second attachment structures.

9. The method of claim 8, further comprising knotting and cutting the suture proximate to the second anchor.

10. The method of claim 4, wherein guiding the device comprises guiding the device from the first and second end of the suture to the tissue plication, such that the tissue plication is positioned between the first and second attachment structures.

11. The method of claim 1, wherein guiding the device comprises guiding the device in an inverted position.

12. The method of claim 11, further comprising extending the device distally within the gastrointestinal tract to a non-inverted position.

13. The method of claim 4, wherein providing comprises providing a flexible tubular device with a Y-shaped attachment structure, wherein the first and second attachment structures comprise a side of the Y.

14. The method of claim 4, wherein providing comprises providing a flexible tubular device with a U-shaped attachment structure, wherein the first and second attachment structures comprise a side of the U.

15. The method of claim 1, wherein guiding the device is performed after extending the suture through the tissue plication.

16. The method of claim 1, wherein the device comprises a flexible tubular cuff

17. The method of claim 1, wherein the device comprises a gastrointestinal bypass sleeve.

18. The method of claim 1, wherein the tissue plication is a stomach wall plication.
