Exhalation delivery systems (EDS) deliver medications to the internal nose. Developed in 2006, ^[1] EDS devices use the patient's exhaled breath to propel medication, such as steroids, ^[1] into the nasal cavities. The method can deliver medication deeper into the nasal passages than intranasal sprays, ^[1] and at a lower pressure than nasal irrigation methods. ^[1]

Using EDS to deliver fluticasone (EDS-FLU) to patients with nasal polyps has been shown to reduce the need for surgery. ^[1]
