A ventilation device (1100) includes a hollow body (1102) having a main portion(1104), at least one distal member (1106) coupled to a distal end (1110) of the main portion and at least one proximal member (1108) coupled to a proximal end (1112) of the main portion. The at least one distal member is formed of a shape memory material. The hollow body includes a deployed state for maintaining an opening in an anatomical structure (1260) and an undeployed state. The shape memory material forms the at least one distal member into a deployed position. The shape memory material is reversibly deformed from the deployed state into the undeployed state such that at least the distal member changes in shape to an undeployed position, while the main portion of the hollow body remains unchanged.
