A multi-lumen insertion tube for use with an endoscope, the multi-lumen insertion tube having a circumferential outer wall defining a main inner lumen, and a plurality of inner septa dividing the main inner lumen into a plurality of lumens. The circumferential outer wall is configured to expand radially outwardly when positive pressure is applied through the insertion tube, and to at least partially collapse against at least one of the inner septa when negative pressure is applied through the insertion tube, such that further collapse of the circumferential wall is prevented by at least one of the inner septa.
