摘要：
A device for maintaining a patent paranasal sinus ostium includes a tubular element having a proximal end, a distal end, and a center region between the proximal end and distal end. The tubular element has an insertion state and a deployment state. The tubular element is locatable in the sinus ostium when in the insertion state and expandable from the insertion state to the deployment state when located in the sinus ostium. In the deployment state, the center region confronts the sinus ostium with an outward radial force.
