Abstract

Abstract Disclosed are method and devices for deploying a guidewire in a lung of a patient. The method comprises removably coupling a distal end of the guidewire to a distal end of a delivery device having an elongated shaft and a lumen extending therethrough. The distal end of the delivery device is delivered through the patient's trachea into a bronchial passageway of the lung so that the distal end of the guidewire is disposed in the bronchial passageway. The delivery device is then removed from the a bronchial passageway while the distal end of the guidewire remains in the bronchial passageway.
