Abstract
A novel aspirating catheter tube inserter, and related methods, which provides for incremental, facile, safe, and efficient unidirectional delivery of an aspirating catheter to the lung of a patient. The disclosed inserter comprises a movable housing which is non-compressibly reciprocally moved relative to a stationary housing to urge the catheter tube to move incrementally into the patient. The inserter comprises resiliently compressible, seizing and releasing washers which accommodate distal displacement of the catheter tube into the patient when the movable housing is linearly moved toward the patient, but seizes and holds the catheter tube from movement when the movable housing is retracted. The catheter seizing and releasing washers also release the catheter from further progress into the lung, when there is an impeding force of a predetermined magnitude which is caused by tissue engagement, to prevent injury. The seizing and releasing washers allow the catheter tube to be physically grasped and pulled proximally from the lungs of the patient.
