Abstract

A device having a cutting implement movable in a direction generally parallel to a tissue surface and creating a cut line that does not extend to the proximal end of tissue adjacent the device is disclosed. The device has a cutting implement that emerges from a tissue engaging surface and cuts tissue only between a proximal and distal ends of the adjoining staple lines. A method is further provided for anastomosing two lumens without extending the passageway between them to the openings made for the forks of the anastomosis device.

Claims

1. A method of creating an anastomosis between two body lumens having tissue walls, said method comprising:

(a) positioning said walls of two body lumens adjacent each other;

(b) creating a small opening in each lumen;

(c) compressing at least a portion of each wall of each body lumen into a plane of tissue;

(d) dissecting the two body lumens by cutting parallel to the plane created by the compressed portion of the two body walls to create a passageway through each wall without extending the passageway into the small openings; and

(e) adhering the touching walls to each other about said passageway.

2. A method according to claim 1 further comprising closing said openings.

3. A method according to claim 2 wherein said closing the openings comprises suturing said openings.

4. A method according to claim 2 wherein said closing the openings comprises stapling said openings closed.

5. A method according to claim 1 wherein said adhering the touching walls to each other about said passageway comprises stapling the walls along at least a portion of the perimeter of the passageway.

6. A method according to claim 1 wherein the lumens comprise portions of the intestines of a surgical patient.

7. A method according to claim 1 wherein one of the lumens comprises a portion of the small intestines of a surgical patient and the other of the lumens comprises a portion of the stomach of a surgical patient.

8. A method according to claim 1 wherein the creation of an anastomosis is a part of gastric bypass surgery.

9. A method of creating an anastomosis between two body lumens having tissue walls, said method comprising:

(a) positioning the walls of the body lumens next to each other;

(b) compressing a portion of each wall of each lumen into a plane of body tissue;

(c) applying at least two rows of staples to adhere the two body lumens to each other; and

(d) cutting parallel to the plane of tissue and only between the proximal end and distal end of the rows of staples to create a passageway while leaving uncut a portion of compressed tissue distal to the proximal end of the rows of staples.

10. A method according to claim 9 wherein the lumens comprise portions of the intestines of a surgical patient.

11. A method according to claim 9 wherein one of the lumens comprises a portion of the small intestines of a surgical patient and the other of the lumens comprises a portion of the stomach of a surgical patient.

12. A method according to claim 9 wherein the creation of an anastomosis is a part of gastric bypass surgery.

13. A method according to claim 9 further comprising:

(a) creating a small opening in each lumen; and

(b) leaving uncut tissue between the small opening and a proximal end of the passageway.

14. A method according to claim 13 further comprising closing the openings.

15. A method according to claim 14 wherein said closing the openings comprises suturing the openings.

16. A method according to claim 14 wherein said closing the openings comprises stapling the openings closed.
