A device for maintaining a plication within a hollow organ. The device includes an elongated member having distal and proximal ends. The distal end is for insertion into a body cavity. The elongated member has an end effector at its distal end. The end effector has an outer cylinder having at least one opening, and an inner cylinder having at least one opening. The inner cylinder is at least partially disposed within the outer cylinder and the cylinders are rotatable with respect to each other. The end effector is detachable from the elongated member such that it can remain within the body cavity.
