A ventilation tube includes a hollow main portion having an inner wall, an outer wall, a distal end and a proximal end. The outer wall defines an outer wall width dimension. At least one distal member is coupled to and extends from the distal end and has an outer end. At least one proximal member is coupled to and extends from the main portion and has an outer end. In an undeployed state, the outer end of the at least one proximal member is more greatly spaced apart from the outer wall width dimension than the outer end of the at least one distal member. In a deployed state the outer end of the at least one distal member changes in position relative to the outer wall width dimension and the outer end of the at least one proximal member remains unchanged relative to the outer wall width dimension.
