1. A device for dilating a stenotic opening of a paranasal sinus in a subject, the device comprising:
(a) a self-expanding driver having an axis and configured to expand from a non-expanded configuration to an expanded configuration, wherein the non-expanded configuration is sized to be positioned within the stenotic sinus opening and wherein the device is sized to be introduced through a nostril opening and a nasal cavity of the subject in order to be positioned in the stenotic sinus opening; and (b) an arm, extending from a proximal end of the device, for removably mounting the device on an insertion tool, the arm having an axis that approximately aligns with the nasal cavity and the nostril opening when the device is positioned in the stenotic sinus opening.
