Abstract

A device and method of promoting tissue adhesion to reinforce tissue apposition that may include collecting advancing a tissue apposition device to a body cavity having cavity calls, collecting tissue from the cavity walls, passing at least one tissue securement device through the tissue, applying energy to the collected tissue to produce injury to the tissue, and apposing the collected tissue and securing the one or more tissue securement devices. In this illustrative embodiment, the device and method promotes tissue adhesion between one or more portions of tissue, wherein the tissue adhesion may reinforce a tissue apposition.

Claims

1. A tissue apposition device comprising:

a member for collecting tissue portions;

a tissue securement device;

an energy emitting member configured to produce an injury to the tissue.

2. The tissue apposition device as in claim 1, wherein the member for collecting a tissue portion comprises a cavity and a vacuum channel adjacent to and in communication with the cavity.

3. The tissue apposition device as in claim 1, wherein the energy comprises electrical energy.

4. The tissue apposition device as in claim 1, wherein the energy comprises radiofrequency energy.

5. The tissue apposition device as in claim 2, wherein the energy emitting mechanism is positioned within the cavity.

6. A tissue apposition device comprising:

a suturing capsule having a tissue suction cavity, wherein the tissue suction cavity comprises a tissue suction cavity wall;

a needle slidable through the tissue suction cavity;

a suture material coupled to the needle; and

an energy emitting component configured to produce an injury to tissue in proximity to the tissue suction cavity.

7. The tissue apposition device as in claim 6, wherein the energy emitting component comprises an electrical energy emitting member.

8. The tissue apposition device as in claim 6, wherein the energy emitting component is positioned within the tissue suction cavity.

9. The tissue apposition device as in claim 8, wherein the energy emitting component is integral with the tissue suction cavity wall.

10. The tissue apposition device as in claim 9, wherein the energy emitting component comprises an electrical circuit.

11. The tissue apposition device as in claim 8, wherein the energy emitting component comprises an electrical circuit operably coupled to the tissue suction cavity wall.

12. The tissue apposition device as in claim 11, wherein the electrical circuit is further comprised of a flexible substrate such that the electrical circuit conforms to the shape of the wall of the tissue suction cavity.

13. The tissue apposition device as in claim 11, wherein the electrical circuit includes a non-conductive layer and a conductive layer.

14. The tissue apposition device as in claim 13, wherein the non-conductive layer comprises polyimide and the conductive layer comprises copper.

15. The tissue apposition device as in claim 13, wherein the conductive layer emits electrical energy to produce an injury to the tissue.

16. The tissue apposition device as in claim 15, wherein the conductive layer is configured to produce even distribution of the injury to the tissue.

17. The tissue apposition device as in claim 6, wherein the tissue apposition device further comprises a vacuum channel adjacent to and in communication with the tissue suction cavity.

18. The tissue apposition device as in claim 17 further comprising of a power channel in electrical communication with the energy emitting component.

19. The tissue apposition device as in claim 18, wherein the power channel is adjacent to the vacuum channel.

20. The tissue apposition device as in claim 19, wherein the power channel is positioned at least partially within the vacuum channel.

21. A method of apposing and securing tissue comprising:

advancing a tissue apposition device to a body cavity having cavity walls;

collecting tissue from the cavity walls;

passing at least one tissue securement devices through the tissue;

applying energy to the collected tissue to produce injury to the tissue; and

apposing the collected tissue and securing the one or more tissue securement devices.

22. The method as in claim 21, wherein the one or more tissue securement devices comprises suture.

23. The method as in claim 21, wherein the energy is electrical energy.

24. A method of collecting, apposing, and securing comprising:

collecting a first tissue portion with a tissue apposition device, wherein the tissue apposition device comprises an energy emitting member;

placing a first tissue securement device through the first tissue portion;

capturing a second tissue portion with the tissue apposition device;

placing a second tissue securement device through the second tissue portion;

applying energy to the first portion of tissue with the energy emitting member to produce an injury to the first portion of tissue; and

approximating the first and second portions of tissue, wherein the injured portion of the first portion of tissue is at least partially in contact with the second portion of tissue.

25. The method as in claim 24, wherein at least one of the first and second tissue securement devices comprises suture.

26. The method as in claim 24, wherein the first and second tissue securement devices are the same.

27. The method as in claim 24, wherein the energy is electrical energy.

28. A method of apposing and securing tissue comprising:

providing a tissue apposition device with a capsule having a tissue suction cavity and an energy emitting member;

advancing the tissue apposition device into a body cavity with cavity walls;

collecting tissue from the cavity walls and configuring the tissue into folds by suctioning a tissue fold into the capsule;

providing a suture and a needle wherein the suture is attached to the needle;

sewing the folds with at least one suture by advancing the needle and suture through the tissue suction cavity and through the tissue fold;

depositing the needle in a distal chamber formed in a distal tip of the capsule;

removing the suction to release the sutured tissue fold;

applying energy to at least a portion of the tissue fold with the energy emitting member to produce injury in the tissue; and

securing the suture to the fold.

29. The method as in claim 28, wherein the energy is electrical energy.
