Dilators are provided for insertion into, and dilation of, a Eustachian tube of an animal, e.g., a human being. The dilators may be placed in the Eustachian tube via the oral or nasal passageway, and the nasopharynx. The dilators are configured to be self-expanding and include a driver configured to expand an expandable portion from a non-expanded configuration to an expanded configuration. Also provided are kits that include the dilator, an insertion device for inserting the dilator, and methods for inserting the dilator into a Eustachian tube. |
