Devices, systems and methods useable for treating sinusitis
First Claim
1. A system for treating sinusitis in a patient, the system comprising:
- (a) a plurality of rigid, or semi-rigid, tubular guide devices, each of which is configured to facilitate advancement of a guidewire, catheter or other device into or through an opening of a paranasal sinus, the guide device comprising;
(i) a tubular proximal portion having a lumen and a distal end, and(ii) a tubular distal portion having a lumen substantially coaxial with the lumen of the proximal portion and a distal end, the distal portion extending from the distal end of the proximal portion, the distal portion being more flexible than the proximal portion and configured to facilitate transnasal insertion and positioning of the guide device such that the distal end of the distal portion is located within or adjacent to the opening of the paranasal sinus; and
(b) a balloon catheter sized and configured for advancement through any selected one or ones of the tubular guide devices and for use in dilating the opening of the paranasal sinus;
wherein the plurality of guide devices include at least a first guide device having a curved, bent or angled region of a first curvature and a second guide device having a curved, bent or angled region of a second curvature that is different from said first curvature.

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.

16. A system for treating sinusitis in a patient, the system comprising:
-
(a) a plurality of tubular guide devices, each of which is configured to facilitate advancement of a guidewire, catheter or other device into or through an opening of a paranasal sinus, the guide device comprising; (i) a tubular proximal portion having a lumen and a distal end, and (ii) a tubular distal portion having a lumen substantially coaxial with the lumen of the proximal portion and a distal end, the distal portion extending from the distal end of the proximal portion, the distal portion being more flexible than the proximal portion, wherein both the proximal portion and the distal portion are configured to be of sufficient rigidity to facilitate transnasal insertion and positioning of the guide device such that the distal end of the distal portion is located within or adjacent to the opening of the paranasal sinus, wherein the distal portion is sufficiently flexible to permit deformation of the distal portion by a user; and (b) a balloon catheter sized and configured for advancement through any selected one or ones of the tubular guide devices and for use in dilating the opening of the paranasal sinus, wherein the balloon catheter comprises a balloon, wherein the balloon is configured to break bone surrounding the opening of the paranasal sinus; wherein the plurality of guide devices include at least a first guide device having a curved, bent or angled region of a first curvature and a second guide device having a curved, bent or angled region of a second curvature that is different from said first curvature.
