VENTILATION DEVICE AND INSERTION SYSTEM THEREFOR

摘要

A ventilation device includes a hollow body having a main portion, at least one distal member coupled to a distal end of the main portion and at least one proximal member coupled to a proximal end 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 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.

主权项

1. A ventilation device comprising:
a hollow body including a main portion having a distal end, a proximal end, an inner wall and an outer wall, at least one distal member coupled to the main portion and at least one proximal member coupled to the main portion and being located a proximal distance from the at least one distal member, the hollow body comprising:
an undeployed state for placing the hollow body into an opening in an anatomical structure, wherein in the undeployed state the at least one distal member assumes a first position and the at least one proximal member protrudes outwardly from the outer wall of the main portion; anda deployed state for maintaining the opening in the anatomical structure, wherein in the deployed state the at least one distal member assumes a second position different from the first position in the undeployed state.
