Self-sealing device and method for delivery of a therapeutic agent through a pneumostoma

A diagnostic system for use in association with an artificial channel which passes through a chest wall, a parietal membrane, a visceral membrane and the parietal membrane surrounding the artificial channel, the diagnostic system comprising:

• a first device which includes:
• a tube adapted to be place in the artificial channel such that a distal end of the tube is positioned within the lung of the patient,
• a flange connected to a proximal end of the tube adapted to secure the first device to the chest wall of the patient and with the tube with the artificial channel and an aperture at the proximal end of the tube;
• a second device that can connect to the aperture of the first device;
• said second device including a diagnostic device that can at least one of provide a diagnostic agent through the tube to the lung and receive a sample of gases through the tub from the lung.

A medical agent delivery system for delivering a medical agent through an artificial channel which passes through chest wall, parietal membrane, visceral membrane and into a lung of a patient, there being a seal between the visceral membrane and the parietal membrane, the medical agent delivery system comprising:

• a pneumostoma management first device which includes a tube adapted to be placed in the artificial channel such that a distal end of the tube is positioned within the lung of a patient,
• a flange connected to a proximal end of the tube adapted to secure the pneumostoma management device to the chest wall of the patient and with the tube within the artificial channel, and an aperture at the proximal end of the tube;
• and
• a medical agent delivery second device includes a self-sealing dispensing port that can selectively communicate with the aperture of the pneumostoma management device in order to provide the medical agent to the lung.
