Devices, systems and methods useable for treating sinusitis
First Claim
1. A method of using a dilation catheter system to treat a patient, the dilation catheter system comprising:
- (a) a steerable guide catheter comprising;
(i) a proximal portion, wherein the proximal portion extends along a longitudinal axis,(ii) a distal end, and(iii) a controllably deformable region, wherein the controllably deformable region is located between the proximal portion and the distal end, wherein the controllably deformable region is configured to deflect the distal end relative to the longitudinal axis; and
(b) an expandable dilator slidably disposed relative to the steerable guide catheter, wherein the expandable dilator is configured to translate relative to the guide catheter from a first position to a second position, wherein the expandable dilator is located proximal to the distal end of the steerable guide catheter in the first position, wherein the expandable dilator located distal to the distal end of the steerable guide catheter in the second position; and
the method comprising;
(a) deforming the controllably deformable region such that the distal end of the steerable guide catheter is adjacent to a targeted passageway associated with drainage of a paranasal sinus of the patient;
(b) inserting the distal end of the steerable guide catheter into a nasal cavity of the patient; and
(c) actuating the expandable dilator through the guide catheter from the first position to the second position such that the expandable dilator extends into the targeted passageway of the patient.

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.

15. A method of using a dilation catheter system to treat a patient, the dilation catheter system comprising:
-
(a) a steerable guide catheter comprising; (i) a proximal portion extending along a longitudinal axis, (ii) a distal end, (iii) a controllably deformable region, wherein the controllably deformable region is located between the proximal portion and the distal end, wherein the controllably deformable region is configured to deflect relative to the longitudinal axis, and (iv) a pull wire coupled near the distal end, wherein the pull is configured to actuate proximally to bend the controllably deformable region relative to the longitudinal axis; and (b) an expandable dilator slidably disposed within the steerable guide catheter, wherein the expandable dilator is configured to actuate through the guide catheter from a first position to a second position, wherein the expandable dilator is located within the steerable guide catheter in the first position, wherein the expandable dilator is distal relative to the distal end of the steerable guide catheter in the second position; and the method comprising; (a) inserting the distal end of the steerable guide catheter into a nasal cavity of the patient; (b) actuating the pull wire proximally, thereby deforming the controllably deformable region to enable positioning of the distal end of the steerable guide catheter adjacent to a targeted passageway associated with drainage of a paranasal sinus of the patient; and (c) actuating the expandable dilator through the guide catheter along the deformed deformable region, from the first position to the second position, such that the expandable dilator extends into the targeted passageway of the patient. - View Dependent Claims (16, 17, 18, 19)

20. A method of using a dilation catheter system to treat a patient, the dilation catheter system comprising:
-
(a) a steerable guide catheter comprising; (i) a proximal portion, wherein the proximal portion extends along a longitudinal axis, (ii) a distal end, and (iii) a controllably deformable region located between the proximal portion and the distal end, wherein the controllably deformable region is configured to deflect the distal end relative to the longitudinal axis; and (b) an expandable dilator slidably disposed relative to the steerable guide catheter, wherein the expandable dilator is configured to translate past the distal end of the steerable guide catheter; and the method comprising; (a) deforming the controllably deformable region such that the distal end of the steerable guide catheter is positioned for insertion into a targeted passageway associated with drainage of a paranasal sinus of the patient; (b) inserting the distal end of the steerable guide catheter into a nasal cavity of the patient; and (c) actuating the expandable dilator relative to the guide catheter, along the deformed deformable region, such that the expandable dilator extends into the targeted passageway of the patient.
