A method of delivering a substance, such as fluticasone propionate, a nasal steroid and/or carbon dioxide gas, to the nasal cavity of a subject, in particular for the treatment of sinus and/or nasal inflammatory diseases, for example, chronic rhinosinusitis with or without nasal polyps, to reduce sinus inflammation, reduce sinus opacification, and/or improve associated symptoms.

Provided herein are systems and methods to generate an inhalable vapor in an electronic vaporization device. The vaporization device may generate a vapor with one or more defined characteristics. In some cases, the vapor may have a predetermined aerosol number density and/or a predetermined average aerosol diameter. The vaporization device may generate a vapor from a vaporizable material. In some cases, the vaporizable material may be a liquid material housed in a cartridge. The vaporization device may comprise a rechargeable power storage device.

Systems and methods to generate an inhalable vapor in an electronic vaporization device. Described herein are cartridges including a vaporizable material that may be securely connected to a rechargeable base unit.

Dry powder inhaler systems for pulmonary delivery of pharmaceuticals are disclosed.

Drug supply units are disclosed which comprise substrates having a plurality of holes formed therein.

A medicament delivery device is provided having an oral tubular section for placement in the mouth of a user and a nasal tubular section for placement in the naris of a user. A medicament located in a corrugated, or flexible, section joining the oral tubular section and the nasal tubular section is dispersed into the nasal cavity of the user by blowing into the oral tubular section. A pinch valve or a one way valve is used to prevent the user from accidentally inhaling the medicament. The medicament delivery device may also be used as a pulmonary delivery device into the mouth of a user.

A nebulizer kit includes: a housing body that houses an atomization portion configured to atomize a liquid and includes a first opening portion and a second opening portion; and a mouthpiece in which a first attachment portion including a first check valve and configured to be attachable to and detachable from the first opening portion and a tubular second attachment portion including a second check valve and configured to be attachable to and detachable from the second opening portion are integrally configured. An inhalation attachment different from the mouthpiece is attachable to the second opening portion in a state in which the mouthpiece is removed from the housing body.

Inhalator comprising an aerosol generator configured to generate an aerosol by nebulizing a fluid and a controller configured to control operation of the aerosol generator and a housing accommodating at least the aerosol generator and the controller, the housing having a base for supporting the housing on a horizontal surface, wherein a portion of the housing accommodating at least a portion of the controller is arranged further away from the base than the aerosol generator as seen in a vertical direction, when the base is supported on the horizontal surface.

Provided herein are systems and methods to generate an inhalable vapor in an electronic vaporization device. The vaporization device may generate a vapor with one or more defined characteristics. In some cases, the vapor may have a predetermined aerosol number density and/or a predetermined average aerosol diameter. The vaporization device may generate a vapor from a vaporizable material.

A vaporizer (20) is shaped to define a flow channel (120) that is open to an environment external to the vaporizer at first and second ends of the flow channel. At the first end of the flow channel is a mouthpiece (112) of the vaporizer. A flow sensor (114) includes (a) a nanoscale resistive element (200) disposed at least partially within the flow channel and (b) sensing circuitry (115) configured to measure a change in the nanoscale resistive element due to airflow within the flow channel. Other applications are also described.
