A handheld therapeutic material delivery system includes a droplet dispersion chamber, a droplet generating assembly for generating droplets of a fluid containing the therapeutic material and for supplying the droplets to the dispersion chamber, and a gas conditioning assembly for supplying heated gas to the dispersion chamber to form a heated transport gas stream. The droplets are dispersed in the heated transport gas stream in the dispersion chamber to provide an aerosol stream containing the droplets. The aerosol stream is supplied to the patient in response to a negative pressure applied by the patient. The delivery system may include a droplet inspection assembly for determining a characteristic of the aerosol stream and a feedback unit responsive to the determined characteristic of the aerosol stream for controlling one or both of the droplet generating assembly and the gas conditioning assembly.
