Devices and methods for placement of partitions within a hollow body organ
First Claim
1. A gastroplasty device used to place plications within a 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 cartridge member opposite an anvil member along a longitudinal axis of the tissue treatment device, the cartridge member and the anvil member being movable between a closed position and an open position relative to one another about the longitudinal axis of the tissue treatment device, the tissue treatment device further comprising a first vacuum pod formed in the cartridge member and a second vacuum pod formed in the anvil member; and
a barrier disposed between the cartridge member and the anvil member of the tissue treatment device;
the barrier separating the first vacuum pod from the second vacuum pod and the barrier having a portion that extends radially outward of the. cartridge member and anvil member when the tissue treatment device is in the closed 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 relative to one another, and the cartridge member is re-loadable with a removable staple cartridge to form multiple plications within the organ with the same tissue treatment device.

13. A method of providing therapy to the stomach cavity of a patient, comprising:
-
inserting a tissue treatment device transorally to the stomach cavity, the tissue treatment device having a cartridge member opposite an anvil member, the cartridge member being loaded with a first removable staple cartridge, the cartridge member having a first vacuum pod formed therein and the anvil member having a second vacuum pod formed therein, and a barrier separating the first vacuum pod from the second vacuum pod; acquiring stomach tissue at a target region for treatment with the first vacuum pod formed in the cartridge member and the second vacuum pod formed in the anvil member of the tissue treatment device; forming a plication within the stomach cavity using staples from the first removable staple cartridge to staple the stomach tissue acquired in the first vacuum pod to the stomach tissue acquired in the second vacuum pod; removing the first removable staple cartridge from the cartridge member; inserting a second removable staple cartridge into the cartridge member; and forming a second plication within the stomach cavity using staples from the second removable staple cartridge. - View Dependent Claims (14, 15, 16, 17)
