摘要:
A mechanically deployable upper airway stent is disclosed along with a method of using same. The stent comprises a central tube having an inner chamber and openings on its surface. A linkage rod is housed within the central tube and is provided with branched spokes that pass through the openings. In the un-deployed state the branched spokes are contained within the central tube. Deployed spokes are preferably aligned in groupings along the central tube. The outer ends of the spokes of each grouping connect to a rib. The un-deployed stent is inserted into the nasal passageway and positioned relative to occluding anatomic structures. Upon deployment, the ribs along with web members extending between the ribs move outwardly from the central tube and press upon the tissues of the pharyngeal cavity. Spaces between the extended spokes permit the passage of air along the stent and maintain airway patency.
