Devices and methods for placement of partitions within a hollow body organ
First Claim
1. A method for reducing the volume of a stomach cavity, comprising:
- inserting a tissue treatment device having a proximal end and a distal end transorally to the stomach cavity, the tissue treatment device having a first jaw opposite a second jaw and the first jaw being loaded with at least one fastener;
positioning the proximal end of the tissue treatment device within the stomach at the region of gastroesophageal junction and the distal end of the tissue treatment device within the stomach cavity;
acquiring tissue above a Z-line and from the stomach with the tissue treatment device; and
forming a plication from the acquired tissue and extending downward into the body of the stomach using the at least one fastener loaded within the first jaw.

Abstract
Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient'"'"'s body to create one or more plications within the hollow body organ. A tissue treatment device attached to a distal end of a flexible elongated member and has a cartridge member opposite an anvil member. The cartridge member and the anvil member are movable between a closed position and an open position, and a moveable barrier is disposed between the cartridge and anvil members to help acquire a dual fold of tissue. The tissue treatment device can be repositioned to form multiple plications within the organ.

13. A method of providing therapy to the stomach cavity of a patient, comprising:
-
inserting at least a portion of a tissue treatment device within the stomach cavity; and forming a pouch extending downward from the gastroesophageal junction into the body of the stomach cavity by placing a first plication at least partially within the stomach cavity with the tissue treatment device, and the pouch having a distal outlet, wherein forming the pouch includes acquiring tissue from above a Z-line and from the stomach with the tissue treatment device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of providing therapy to the stomach cavity of a patient, comprising:
-
inserting at least a portion of a tissue treatment device within the stomach cavity; forming a first plication with the tissue treatment device, the first plication extending downward from the gastroesophageal junction into the stomach cavity, and wherein forming the first plication includes acquiring tissue from above a Z-line and from the stomach with the tissue treatment device to form the first plication; repositioning the tissue treatment device near a distal end of the first plication; and forming a second plication near the first plication with the tissue treatment device, wherein the first and second plications form a pouch along a lesser curve of the stomach with a distal outlet. - View Dependent Claims (24, 25, 26, 27, 28, 29)
