Devices and methods for placement of partitions within a hollow body organ
First Claim
1. A gastroplasty device used to place plications within at least one cavity, comprising:
- a flexible elongated member having a proximal end and a distal end, and a lumen disposed between the proximal end and the distal end;
a handle attached to the proximal end;
a tissue treatment device attached to the distal end of the flexible elongated member and having a first jaw opposite a second jaw being movably operable between a closed position and an open position, and the first jaw and the second jaw each having a releasably adhering region for acquiring tissue of the at least one cavity;
a septum slidably attached to a rail disposed between the first jaw and the second jaw, and the septum being moveable from a first position to a second position, wherein the septum in the first position separates tissue acquired by the releasably adhering regions of the first and second jaws, and in the second position the septum is distal to the first position.

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.

21. 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 from the gastroesophageal junction and the stomach with the tissue treatment device; and
forming a plication extending from the gastroesophageal junction downward into the body of the stomach using the at least one fastener loaded within the first jaw. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. 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. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. 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;
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 the lesser curve of the stomach with a distal outlet. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50)
