Abstract: A single-dose cartridge inhaler comprises a dosing chamber configured to contain dry powder medicament, a transducer and a controller electrically coupled to the transducer. The medicament delivery device is capable of delivering a therapeutically effective dose of dry powder medicament in response to between 2-20 tidal inhalations, the dose preferably having a mass median aerodynamic diameter (MMAD) of about 6 microns or less and a fine particle fraction of at least 30%.

Abstract: A intranasal device and method for self-administration of a medicament are provided. The intranasal device includes a body, a catheter, a feedback mechanism, and a delivery system. The body has a chamber configured to store the medicament. The body defines a channel that extends from an interior of the body to an exterior of the body. The catheter is configured to be actuated to extend from the body through the channel and is in fluid communication with the chamber. A distal end of the catheter is configured for entry into a nasal passage of a patient. The feedback mechanism is configured to indicate a position of the distal end of the catheter within the nasal passage. The delivery system is configured to deliver the medicament from the chamber into the nasal passage via the catheter.
