摘要:
A ventilation device (1100) includesa hollow body (1102) having a mainportion(1104), at least one distal member(1106) coupled to a distal end (1110) of themain portion and at least one proximal member(1108) coupled to a proximal end (1112) of themain portion. The at least one distal member isformed of a shape memory material. The hollowbody includes a deployed state for maintainingan opening in an anatomical structure(1260) and an undeployed state. The shapememory material forms the at least one distalmember into a deployed position. The shapememory material is reversibly deformed fromthe deployed state into the undeployed statesuch that at least the distal member changes inshape to an undeployed position, while themain portion of the hollow body remainsunchanged.
