| 1. A method for delivering a medicament to a treatment site through an artificial airway associated with a patient ventilation/aspiration
system, comprising:
establishing an artificial airway through the trachea of a patient to a treatment site;
connecting a manifold with an interior chamber communicating with first, second and third ports, structured and arranged to
maintain a travel path for a suction catheter between said first and second ports and an uninterrupted ventilation pathway
between said second and third ports to an entry of said artificial airway;
providing a catheter assembly in communication with said first port, a proximal end of said catheter assembly carrying structure
that is constructed to interconnect to a vacuum control valve;
connecting a storage and delivery component containing a supply of medicament to said proximal end of said catheter assembly;
advancing a catheter of said catheter assembly to said treatment site;
operating said storage and delivery component to discharge medicament through a lumen of said catheter to said treatment site;
removing said storage and delivery component from said proximal end of said catheter assembly; and
connecting a suction control device to said proximal end of said catheter assembly to effect suction through the lumen of
said catheter through which the medicament is discharged.
