Abstract

A system for creating an invaginated portion in a stomach comprises a suction device and a securing member. The suction device comprises a suction head operable to provide suction, a shaft connected to the suction head, and a vacuum lumen in fluid communication with the suction head. The suction head and vacuum lumen are operable to induce a vacuum adjacent to tissue. The suction device is further operable to create an invaginated portion with the tissue. The securing member is operable to substantially maintain the configuration of the invaginated portion of tissue. The suction device may comprise gripping jaw members having teeth. The securing member may comprise an adhesive and/or sutures and the like. The system may be used to create invaginated portions within a stomach. Such invaginated portions may reduce stomach volume to address obesity or other conditions.

Claims

1. A system for creating an invaginated portion in a stomach, the system comprising:

(a) a suction device, wherein the suction device comprises;

(i) a suction head operable to provide suction,

(ii) a shaft, wherein the suction head is connected to the shaft, and

(iii) a vacuum lumen in fluid communication with the suction head, wherein the suction device is configured for the suction head to be placed adjacent to tissue, wherein the suction head and vacuum lumen are operable to induce a vacuum adjacent to the tissue, wherein the suction device is further operable to create an invaginated portion with the tissue; and

(b) a securing member, wherein the securing member is operable to substantially maintain the configuration of the invaginated portion of tissue.

2. The system of claim 1, wherein the suction head has an annular, outwardly flared rim.

3. The system of claim 1, wherein the suction head further comprises a plurality of gripping jaw members, wherein the gripping jaw members are operable to be placed in an open position or a closed position.

4. The system of claim 3, wherein the suction head further comprises a vacuum port positioned near the gripping jaw members.

5. The system of claim 3, wherein the gripping jaw members each comprise a vacuum chamber.

6. The system of claim 3, wherein each of the gripping jaw members comprises a generally spherically-shaped joint portion, wherein at least part of the joint portions overlap when the gripping jaw members are in an open position.

7. The system of claim 1, wherein the securing member comprises an adhesive.

8. The system of claim 7, wherein the adhesive comprises one or both of a cyanoacrylate or an isocyanate.

9. The system of claim 7, wherein the securing member further comprises an activator configured to activate the adhesive.

10. The system of claim 7, wherein the securing member further comprises a matrix, wherein the activator is provided within the matrix.

11. The system of claim 1, wherein the securing member comprises one or more of a suture, a staple, or a clip.

12. The system of claim 1, wherein the securing member is configured to be applied endoscopically.

13. The system of claim 1, wherein the shaft has an interior wall, wherein the vacuum lumen is provided by the interior wall of the shaft.

14. A method of creating invaginated portions in a stomach, the method comprising:

(a) providing a suction device, wherein the suction device comprises;

(i) a suction head operable to provide suction,

(ii) a shaft, wherein the suction head is connected to the shaft, and

(iii) a vacuum lumen in fluid communication with the suction head;

(b) providing a securing member;

(c) positioning the suction head adjacent to tissue;

(d) inducing a vacuum within the vacuum lumen;

(e) creating an invaginated portion with the tissue using the induced vacuum; and

(f) maintaining the configuration of the invaginated portion of tissue using the securing member.

15. The method of claim 14, wherein the securing member comprises an adhesive.

16. The method of claim 15, wherein the suction head is positioned adjacent to a first tissue surface, the method further comprising applying the adhesive to a second tissue surface opposite to the first tissue surface.

17. The method of claim 14, wherein the suction device further comprises pivoting jaw members having teeth, the method further comprising engaging the tissue with the teeth.

18. The method of claim 17, wherein the act of creating an invaginated portion with the tissue comprises moving the jaw members from an open position to a closed position.

19. The method of claim 14, wherein the suction head has an annular, outwardly flared rim, wherein the act of creating an invaginated portion with the tissue comprises drawing the tissue through the rim into the suction head.

20. A system for creating an invaginated portion in a stomach, the system comprising:

(a) a means for inducing a vacuum adjacent tissue;

(b) a means for creating an invaginated portion of the tissue; and

(c) a means for maintaining the configuration of the invaginated portion of the tissue created by the means for creating an invaginated portion.
