Abstract

A system, device or method uses surface energy to assist in fluid transport or separation. One example includes removing mucus from a subject's lungs during mechanical ventilation of the subject using a tracheal tube. At least one wicking fluid pickup port is located more distal or more proximal than a sealing device between the tracheal tube and the trachea. Surface energy assists in introducing mucus into the port. A peristalsis or other pump is used to remove from the subject the wicked-in liquid. Ventilation is not impaired by the mucus removal.
