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.

Claims

1. A system for treating sinusitis in a patient, the system comprising:

a tubular guide device for facilitating advancement of a guidewire, catheter or other device into or through an opening of a paranasal sinus, the guide device comprising;

a tubular proximal portion having a lumen and a distal end; and

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

a balloon catheter sized and configured for advancement through the tubular guide device for dilating the opening of the paranasal sinus.

2. A system as in claim 1, further comprising a guidewire advanceable through the tubular guide device and into the paranasal sinus or opening of the paranasal sinus, wherein the balloon catheter is advanceable over the guidewire.

3. A system as in claim 1, further comprising a tubular sheath advanceable through the tubular guide device and into the paranasal sinus or opening of the paranasal sinus.

4. A system according to claim 1, wherein the tubular guide device has a length in the range of about 5 inches to about 6 inches, and the balloon catheter has a length in the range or about 8 inches to about 20 inches.

5. A system according to claim 1, wherein the balloon catheter comprises:

a catheter shaft;

an inflatable balloon; and

at least one marker that indicates a position of the balloon after it has been inserted into the patient.

6. A system according to claim 5, wherein the at least one marker indicates the position of the balloon relative to the distal end of the tubular guide.

7. A system according to claim 6, wherein the at least one marker comprises:

a first marker indicating the position of the distal end of the balloon catheter relative to the distal end of the tubular guide; and

a second marker indicating the position of the balloon relative to the distal end of the tubular guide device.

8. A system according to claim 7, wherein the balloon has a proximal end and a distal end, and wherein second marker indicates the position of the distal of the balloon relative to the distal end of the tubular guide device and the position of the proximal end of the balloon relative to the distal end of the tubular guide device.

9. A system according to claim 1, wherein the balloon catheter comprises a substantially non-compliant balloon.

10. A system according to claim 9, wherein the balloon is formed of a material selected from the group consisting of:

polyethylene teraphthalate, nylon and polyamide.

11. A system according to claim 9, wherein the balloon is capable of breaking bone located around the opening of the paranasal sinus.

12. A system according to claim 1, wherein the balloon catheter further comprises at least one radiographically visible component that is useable in conjunction with a radiographic imaging device to determine when a balloon of the catheter is positioned within an opening of a paranasal sinus.

13. A system according to claim 1, wherein the balloon catheter has a length of less than about 20 cm.

14. A system according to claim 1, further comprising a plurality of tubular guide devices, the distal portion of each tubular guide device having angle of curvature.
