    Abstract: A device for coating dry powder microparticles onto a surfacemay include a jet mill configured to mill dry powder particles into microparticles having a desired aerodynamic diameter and to deaggregate the microparticles, a feed hopper structured and arranged to feed dry powder particles to the jet mill, a surface configured to receive dry powder microparticles and an exit nozzle associated with the jet mill. The exit nozzle may be arranged to direct deaggregated micronized dry powder particles from the jet mill to the surface to be coated. The device may further include a holder structured and arranged to hold an item, wherein the item includes the surface. In some aspects of the device, the item may be a film.

    Abstract: A dry powder inhaler including a housing defining a chamber for receiving a dose of powdered medicament, an inhalation port in fluid communication with the chamber, at least one airflow inlet providing fluid communication between the chamber and an exterior of the housing, and a flutter element in the chamber and associated with a dose of powdered medicament. The flutter element has a tensioned distal end proximate the at least one airflow inlet and a free proximal end opposite to the distal end and downstream of the inlet. The flutter element is configured to vibrate in response to airflow through the chamber and aerosolize the dose of powdered medicament.
