Abstract: A medical device for tissue manipulation within a body cavity includes a shaft having a lumen extending therethrough from a proximal end to a distal end and a first channel extending within the lumen, an expandable end-effector extending from a proximal end to a distal end, and an expansion mechanism. The end-effector includes a first portion and a second portion and is movable from a first configuration in which the first and second portions are adjacent to one another to a second configuration in which the first and second portions are separated along an axis perpendicular to a longitudinal axis of the shaft. The expansion mechanism is positioned between the first and second portions and expandable to move the end effector from the first configuration to the second configuration.
