| 摘要 |
The present invention relates to a method of introducing biologic materials into the conducting airways of the bronchial system. The invention involves the use of a liquid carrier or suspension for the biologic materials, delivered in relatively large droplet form at a velocity greater than the air velocity of the normally breathing subject. This method also can be used for localized delivery of such biologic materials, including diagnostic and imaging agents, into other gas-filled body cavities.
