Abstract: The present invention relates to an inhaler which comprises a durable unit and a replaceable (cartridge) unit, and which comprises systems, subsystems and elements to provide an “open-inhale-close” user experience. A durable unit comprises a breath-actuated trigger mechanism, and optionally electronics for providing user feedback, and telehealth can capability. A replaceable unit comprises a mouthpiece, blister strip, aerosol path dose counter and a blister piercing and aerosolization engine assembly assembly. A lockout mechanism may be provided to prevent further use of the cartridge when the dose counter reaches a preselected limit, such as zero.

Abstract: The invention provides various apparatus and methods for aerosolizing a powdered medicament. In one exemplary embodiment, an apparatus includes a pressurization cylinder, and a piston which is slidable within the cylinder to pressurize a gas. A handle is coupled to the piston and is movable between an extended position and a home position to pressurize the gas. An aerosolizing mechanism is included and is configured to aerosolize a powdered medicament that is held within a receptacle with pressurized gas from the cylinder. A carriage assembly is included to receive the receptacle and to couple the receptacle to the aerosolizing mechanism. A first and a second interlock are operably engageable with the carriage assembly to prevent coupling of the receptacle with the aerosolization mechanism. The first interlock is released to allow movement of the carriage upon movement of the handle to the extended position.
