Abstract

Sinusitis, mucocysts, tumors, infections, hearing disorders, choanal atresia, fractures and other disorders of the paranasal sinuses, Eustachian tubes, Lachrymal ducts and other ear, nose, throat and mouth structures are diagnosed and/or treated using minimally invasive approaches and, in many cases, flexible catheters as opposed to instruments having rigid shafts. Various diagnostic procedures and devices are used to perform imaging studies, mucus flow studies, air/gas flow studies, anatomic dimension studies and endoscopic studies. Access and occluding devices may be used to facilitate insertion of working devices such asendoscopes, wires, probes, needles, catheters, balloon catheters, dilation catheters, dilators, balloons, tissue cutting or remodeling devices, suction or irrigation devices, imaging devices, sizing devices, biopsy devices, image-guided devices containing sensors or transmitters, electrosurgical devices, energy emitting devices, devices for injecting diagnostic or therapeutic agents, devices for implanting devices such as stents, substance eluting or delivering devices and implants, etc.

Claims

1. A device for insertion into a paranasal sinus, Eustachian tube, naso-lacrimal duct or other anatomical structure of the ear, nose or throat and for guiding a second device to that paranasal sinus, Eustachian tube, naso-lacrimal duct or other anatomical structure, said device comprising:

an elongate shaft having a proximal end and a distal end, at least a portion of said shaft being formed of plastically deformable material such that it may be bent into a desired shape;

a bulbous tip member on the distal end of the shaft; and

a handle removably attachable to the proximal end of the shaft.

2. A system comprising a) device according to claim 1 in combination with b) a second device that is advanceable over said shaft when the handle is detached from the proximal end of the shaft.

3. A system according to claim 2 wherein the second device comprises a catheter.

4. A system according to claim 3 wherein the catheter comprises a balloon catheter.
