Abstract
A guidewire includes a guidewire shaft and an inflatable element arranged at a distal end of the guidewire shaft. At least a portion of the guidewire shaft is formed of metal, and the guidewire shaft includes a lumen that fluidly communicates with an interior of the inflatable element. The inflatable element is operable to transition between a deflated state in which the inflatable element is configured to pass through an isthmus of a Eustachian tube (ET), and an inflated state in which the inflatable element is configured to dilate the ET.
