International Classification:

A61M 15/00

Abstract:

A droplet delivery device with a small volume drug ampoule and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The droplet delivery device is configured to facilitate the ejection of small, e.g., single use, volumes of a therapeutic agent. The droplet delivery device includes a housing, a mouthpiece, a small volume drug ampoule, an ejector mechanism, and at least one differential pressure sensor. The delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The droplet delivery device is then actuated to generate a plume of droplets having an average ejected particle diameter within the respirable size range, e.g, less than about 5-6 μm, so as to target the pulmonary system of the user. The small volume drug ampoule may include a reservoir which comprises an internal flexible membrane separating two internal volumes, a first background pressure fluid volume and a second drug volume.

Abstract:

A nasal droplet delivery device and related methods for delivering precise and repeatable dosages to a subject via the nasal passageways and sinus cavities is disclosed. The droplet delivery device includes a housing, a nosepiece, a reservoir, an ejector mechanism, and at least one differential pressure sensor. The droplet delivery device is automatically actuated by the user when the differential pressure sensor senses a predetermined pressure change within the nosepiece. The droplet delivery device is then actuated to generate a plume of droplets having an average ejected particle diameter of greater than about 6 microns, preferably greater than about 10 micron, so as to target the nasal passageways and sinus cavities of the user.
