DEVICE FOR MAINTAINING PATENT PARANASAL SINUS OSTIA

摘要

There is disclosed a method for maintaining a patent paranasal sinus ostium. In an embodiment, the method includes delivering a tubular element in an insertion state to the sinus ostium. The tubular element includes a proximal end, a distal end, and a center region between the proximal end and distal end. The method includes expanding the tubular element from the insertion state to a deployment state when located in the sinus ostium. In the deployment state, the center region confronts the sinus ostium with an outward radial force.
