1. A particle dispersion chamber comprising:
- a housing having an external surface, a particle input end, and outputs opening, and an internal channel between the particle input end and the output opening, the channel generally defining a channel axis and a forward direction toward the output opening, the internal channel having a substantially continuous cross-sectional area from the particle input end of the housing to, and including the output opening; and
a plurality of directional fluid outputs configured within the housing to direct output at an acute forward angle with respect to the channel axis and output opening, wherein the fluid outputs, when fluid flows therefrom, are operative to impart a vortical flow to aerosolized particles exiting the output opening.

16. A method of delivering aerosolized particles into a nasal cavity of a subject, comprising:
-
providing a particle delivery chamber, comprising a housing having an external surface, a particle input end, and output opening, an internal channel between the particle input end and the output opening, the internal channel generally defining a channel axis and a forward direction toward the output opening, the housing additionally having at least one directed fluid output channel configured to direct fluid output at an acute forward angle with respect to the channel axis and output opening; introducing aerosolized particles into the internal channel; imparting, using fluid flow from the at least one directed fluid output channel, a vortical flow pattern to said particles exiting the output opening of the internal channel; and delivering the vortically flowing particles into a nasal cavity of the subject, wherein a method of delivering aerosolized particles to the nasal cavity is afforded. - View Dependent Claims (17, 18)
