Abstract
Sinusitis and other disorders of the ear, nose and throat are diagnosed and/or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.) into the paranasal sinuses or other structures in the ear, nose or throat. Specific devices (e.g., tubular guides, guidewires, balloon catheters, tubular sheaths) are provided as are methods for manufacturing and using such devices to treat disorders of the ear, nose or throat.

-
(a) advancing a guide device into the patient'"'"'s head to position a distal end of the guide device near or within a paranasal sinus ostium; (b) advancing a balloon catheter over or through the guide device to position a balloon of the catheter within the paranasal sinus ostium; (c) remodeling the paranasal sinus ostium by expanding the balloon within the passageway to enlarge the paranasal sinus ostium; (d) introducing irrigation fluid into a sinus cavity associated with the paranasal sinus ostium using an irrigation device; and (e) removing the balloon catheter, irrigation device and guide device from the head.
