Abstract

A device for accessing dry powder within a sealed chamber is described. The device includes a hollow housing having a proximal end opening, a primary distal end opening and a secondary distal end opening, at least one wing structure extending from the outer surface of the housing that is positioned distally from the primary distal opening. Also described is a dry powder inhaler having a housing, apenetrating component for accessing dry powder within a sealed chamber, and a mouthpiece, where the mouthpiece is connected to the proximal end opening of the penetrating component, and wherein the at least a portion of the distal end of the penetrating component is positioned within the inhaler housing.
