Abstract
A method for aerosolizing a powdered medicament comprises coupling a powder inlet end of a feed tube with a penetration in a receptacle containing the powder. Powder is drawn upward through the tube and dispersed in a high pressure gas stream flowing past a portion of the feed tube. Apparatus comprise the feed tube mounted within a base enclosure proximate a holder for one or more receptacles, which may be in the form of a cartridge containing a plurality of receptacles formed in a continuous web. The cartridge may be reciprocated relative to the feed tube and a separate piercing mechanism in order to sequentially piercing the receptacle and thereafter couple the feed tube through the resulting penetration for extracting the powder. Alternatively, penetration(s) through the receptacle may be formed as the feed tube is coupled, or some penetrations formed prior to coupling with other penetrations formed at the time of coupling.
