Abstract
A system for dilating the sinus ostia with a device including a series of elongated members, each having a central channel and increasing outer diameters where the members are positioned one over the other such that the members are advanced to incrementally dilate the sinus ostia. The central channels of each member allow for various procedures to be performed including, for example, the application of wireless energy (e.g., ultrasonic, RF, etc.) to the sinus ostia, the introduction of an irrigating fluid and aspiration from the sinus ostia, and the introduction of a drug to the sinus ostia.
