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 for gastric volume reduction, comprising:

advancing a tissue acquisition and fixation device endoscopically through an esophagus and into a stomach;

manipulating the tissue acquisition and fixation device within the stomach to form a first fold of tissue on an interior surface of an anterior wall of the stomach;

manipulating the tissue acquisition and fixation device within the stomach to form a second fold of tissue on an interior surface of a posterior wall of the stomach, wherein the second fold is not attached to the first fold;

wherein manipulating the tissue acquisition and fixation device comprises positioning first and second jaws of the tissue acquisition and fixation device to extend substantiall parallel to the anterior wall of the stomach, pivoting the first and second jaws toward an open position, and drawing tissue through the first and second jaws using a tissue acquisition member to form the first and second folds.

2. The method of claim 1, wherein a first fastener secures the first fold and a second fastener secures the second fold.

3. The method of claim 1, 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.

4. The method of claim 1, further comprising securing the first fold with at least one row of fasteners and securing the second fold with at least one row of fasteners.

5. The method of claim 1, wherein acquiring tissue comprises activating a vacuum source to draw tissue to the tissue acquisition member of the tissue acquisition and fixation device.

6. The method of claim 5, wherein acquiring tissue further comprises engaging a secondary acquirer coupled to the tissue acquisition member to retain the tissue in position relative to the tissue acquisition member.

7. The method of claim 1, wherein manipulating the tissue acquisition and fixation device further comprises moving the tissue acquisition member from a first position, in which a distance between a longitudinal axis of the tissue acquisition member and a longitudinal axis of at least one of the first and second jaws is minimized, to a second position in which the tissue acquisition member is offset from the first and second jaws such that the distance between the longitudinal axes of the tissue acquisition member and the at least one of the first and second jaws is greater than in the first position.
