1. A method for targeted delivery of a liquid microvolume containing therapeutics into a lung, comprising
positioning a steerable catheter device into a pulmonary airway of a lung, wherein the steerable catheter device comprises a distal section with a distal tip and an inner lumen;
steering the distal section of the steerable catheter device to position the distal tip proximal to a desired locus within the pulmonary airway,
instilling a liquid microvolume from the inner lumen of the steerable catheter device to an inner surface of the pulmonary airway;
forming a plug of the liquid across a diameter of the pulmonary airway; and transporting the plug distally through the airway with air pressure delivered from the inner lumen of the elongated tubular member, thereby depositing a film comprising a portion of the liquid microvolume behind the plug.
