Abstract
A system for tissue approximation and fixation is described herein. A device is advanced in a minimally invasive manner within a patient'"'"'s body to create one or several divisions or plications within a hollow body organ. The system comprises a stapler assembly having a tissue acquisition member and a tissue fixation member. The stapler assembly approximates tissue from within the hollow body organ with the acquisition member and then affixes the approximated tissue with the fixation member. In one method, the system can be used as a secondary procedure to reduce the size of a stoma within the hollow body organ.

17. A tissue fixation device, comprising:
-
a flexible shaft having a proximal end and a distal end; and
a cartridge assembly connected to the distal end of the elongated body having an acquisition member and a fixation member, wherein the fixation member includes a first jaw and a second jaw capable of pivoting relative to one another from a closed position to an open position, and the acquisition member includes a vacuum pod fixed to at least one of the first and second jaws;
wherein when the first and second jaws are in the open position, the vacuum pod acquires and holds at least one fold of tissue between the first and second jaws, and the first and second jaws pivot into the closed position to plicate the tissue.

18. A method of acquiring and affixing tissue from within a hollow body organ, comprising:
-
positioning a cartridge assembly attached to a distal end of an elongated body within the hollow body organ adjacent to a region of tissue to be acquired;
articulating at least one jaw of the cartridge assembly from a closed configuration to an open configuration;
acquiring the region of tissue with an acquisition member attached to at least a portion of the cartridge assembly, the region of tissue is acquired and held between the at least one jaw of the cartridge assembly; and
affixing the acquired tissue by articulating the at least one jaw of the cartridge assembly from the open configuration to the closed configuration. - View Dependent Claims (19, 20, 21, 22, 23, 24)

28. A method of treating tissue within a hollow body organ, comprising:
-
placing at least one initial plication within the hollow body organ forming at least one reduced orifice having an inlet and an outlet; and

30. A method of treating tissue within a hollow body organ, comprising:
-
placing at least one initial plication within the hollow body organ forming at least one reduced orifice having an inlet and an outlet; and
performing at least one secondary procedure to reduce the outlet formed by the at least one initial placation, the secondary procedure being chosen from the group consisting of;
placing an additional plication at or near the outlet, injecting a bulking agent at or near the outlet, placing a valve at or near the outlet, placing a stent at or near the outlet, laparoscopically placing an external band at or near the outlet, placing an internal band at or near the outlet, applying energy to the tissue at or near the outlet, and applying a caustic agent or schlerosing agent at or near the outlet.
