US 2007/0167960 A1 · Devices and methods for placement of partitions within a hollow body organ

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.

Dependent claims

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.
