The apparatus also includes an inflatable balloon having a valve that is detachably coupled to a distal end of the second tube such that a portion of the distal end extends through the valve. The balloon is adapted to be introduced to a space in a body and inflated in the space in the body by fluid introduced through the valve through the second tube.
