Publication number: 20150250992Abstract: Devices and methods for dilating the ostia of paranasal sinuses and other passageways within the ear, nose and throat. A mechanical dilator is inserted through a nostril and used to dilate an ostium or a paranasal sinus or other passageway within the ear, nose or throat (e.g., a Eustachian tube or nasolacrimal duct). The mechanical dilator may be an expandable dilators that comprises one or more non-balloon structures with or without an accompanying balloon or a members of varying diameter or cross dimension (e.g., a tapered member) that may be advanced into the ostium or other passageway to cause dilation of that passageway.Type: ApplicationFiled: March 16, 2015Publication date: September 10, 2015Inventors: John H.
