Abstract

Devices and methods are provided for forming and securing a tissue plication. More particularly, the devices and methods of the present invention can be used to create multiple tissue folds on an anterior and posterior wall of a stomach cavity to reduce the volume thereof. In one aspect, a method of gastric volume reduction is disclosed that includes advancing a tissue acquisition and fixation device endoscopically into a stomach, manipulating the device to form a first fold of tissue on an interior surface of an anterior wall of the stomach, and manipulating the device to form a second fold of tissue on an interior surface of a posterior wall of the stomach, where the second fold is not attached to the first fold.

Claims

1. A method of gastric volume reduction, comprising:

advancing an end effector of a surgical device endoscopically through an esophagus and into a stomach with first and second jaws of the end effector being in a closed position;

articulating the end effector of the device to a first position in the fundus of the stomach;

moving the first and second jaws in the stomach from the closed position to an open position to increase a space between facing tissue-contacting surfaces of the first and second jaws; and

moving a tissue acquisition member of the end effector away from the first and second jaws in the open position, thereby drawing tissue into the space between the facing tissue-contacting surfaces of the first and second jaws and forming a first fold of tissue.

2. The method of claim 1, wherein the end effector is articulated to access tissue on any of the anterior and posterior wall of the stomach in the fundus.

3. The method of claim 1, further comprising inserting at least one fastener through the first fold of tissue.

4. The method of claim 1, further comprising:

positioning the end effector with the first and second jaws of the end effector extending substantially parallel to a tissue surface and the tissue acquisition member extending parallel to the tissue surface and positioned on an opposite side of the jaws from the tissue surface.

5. The method of claim 4, wherein moving the tissue acquisition member includes moving the tissue acquisition member away from the first and second jaws while maintaining the parallel orientation of the tissue acquisition member and the tissue surface to draw the tissue through the first and second jaws.

6. The method of claim 1, further comprising:

articulating the end effector of the device to a second position after forming the first fold of tissue on the tissue surface; and

forming a second fold of tissue that is not attached to the first fold of tissue using the end effector.

7. The method of claim 6, further comprising inserting at least one fastener through the first fold of tissue, and inserting at least one fastener through the second fold of tissue.

8. The method of claim 6, wherein the first fold of tissue is formed on an anterior wall of the stomach and the second fold of tissue is formed on a posterior wall of the stomach.

9. The method of claim 6, wherein the second fold of tissue is also in the fundus.

10. The method of claim 6, wherein the second fold of tissue is outside the fundus.

11. The method of claim 6, wherein the second fold of tissue is in the antrum.

12. The method of claim 6, wherein the first and second folds of tissue are formed in any of a fan-shaped pattern and an end-to-end pattern.

13. The method of claim 6, further comprising:

forming a third fold of tissue that is not attached to the first or second folds of tissue using the end effector,

wherein the second and third folds of tissue are formed in a distal-to-proximal direction.

14. The method of claim 1, wherein the first and second jaws are connected to one another at a pivot point in a proximal base portion of the end effector, and the tissue acquisition member is hingedly connected to the proximal base portion of the end effector.

15. The method of claim 14, wherein the tissue acquisition member is hingedly connected to the proximal base portion of the end effector with a hinge mechanism, and moving the tissue acquisition member includes actuating the hinge mechanism.

16. The method of claim 14, wherein moving the tissue acquisition member includes moving the tissue acquisition member in a direction transverse to a longitudinal axis of the first jaw.

17. The method of claim 14, further comprising changing the first and second jaws in the stomach from being in a closed position to being in an open position,

wherein a first plane extends through the first and second jaws in the open position;

and

wherein moving the tissue acquisition member includes moving the tissue acquisition member in a second plane that is perpendicular to the first plane.

18. The method of claim 14, further comprising changing the first and second jaws in the stomach from being in a closed position to being in an open position;

wherein moving the tissue acquisition member includes moving the tissue acquisition member away from the first and second jaws in the open position; and

the first fold of tissue is positioned between the first and second jaws.

19. The method of claim 14, wherein, after articulating the end effector, an angle between a longitudinal axis of the end effector and a longitudinal axis of an elongate shaft of the surgical device is about 180°
