1. A method for maintaining a patent paranasal sinus ostium, the method comprising:
- delivering a tubular element in an insertion state to the sinus ostium, wherein the tubular element includes a proximal end, a distal end, and a center region between the proximal end and distal end; and
expanding the tubular element from the insertion state to a deployment state when located in the sinus ostium by partially melting the tubular element to allow reshaping of the tubular element from the insertion state to the deployment state, wherein, in the deployment state, the center region confronts the sinus ostium with an outward radial force.

Abstract
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.

9. A method for maintaining a patent paranasal sinus ostium, the method comprising:
-
delivering a tubular element in an insertion state to the sinus ostium, wherein the tubular element includes a proximal end, a distal end, and a center region between the proximal end and distal end; expanding the tubular element from the insertion state to a deployment state when located in the sinus ostium by partially melting the tubular element to allow reshaping of the tubular element from the insertion state to the deployment state; and providing a constant outward radial force from the tubular element to the sinus ostium, wherein, in the deployment state, the center region is configured to confront the sinus ostium with the constant outward radial force to counteract a constant centripetal force of scar tissue formation during healing of the sinus ostium. - View Dependent Claims (10)

-
delivering a tubular element in an insertion state to the sinus ostium, wherein the tubular element includes a proximal end, a distal end, and a center region between the proximal end and distal end; and expanding the tubular element from the insertion state to a deployment state when located in the sinus ostium, wherein, in the deployment state, the center region confronts the sinus ostium with an outward radial force; wherein the delivering step comprises; positioning the tubular element around an elastomeric member connected to first and second holding members of an insertion device; and positioning the tubular element in the sinus ostium with the insertion device; wherein the expanding step comprises; actuating the insertion device in a first direction to translate the second holding member toward the first holding member to expand the elastomeric member. - View Dependent Claims (12)
