Devices, systems and methods for treating disorders of the ear, nose and throat
First Claim
1. A method for treating a flowable-substance-containing structure located within a paranasal sinus, said method comprising the steps of:
- advancing a distal end of a guide device to a position in or near an opening into a paranasal sinus;
advancing a penetrator over or through the guide into the paranasal sinus;
advancing the penetrator into the flowable-substance-containing structure to form an opening in the structure; and
expanding a compressor in the paranasal sinus to compress the flowable-substance-containing structure and thus force flowable substance out of the opening formed by the penetrator.

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.

8. A method for treating a flowable-substance-containing structure located within a paranasal sinus, said method comprising the steps of:
-
advancing a tubular guide device through a nostril to a position a distal end of the guide in or near an opening into a paranasal sinus; advancing a penetrator/compressor device through the guide device into the paranasal sinus; advancing a penetrating member of the penetrator/compressor into the flowable-substance-containing structure to form an opening in the structure; and expanding a compressing member of the penetrator/compressor in the paranasal sinus to compress the flowable-substance-containing structure such that its contents will be forced out of the opening formed by the penetrating member. - View Dependent Claims (9, 10, 11)
