1. A method of promoting lung disinsufflation, the method comprising:
inserting a catheter distally into a respiratory passageway of a patient's lung, the catheter containing an implantable artificial bronchus disposed within the catheter in a compressed state, the implantable artificial bronchus comprising:
a body including a proximal portion having a proximal upper opening, a distal portion having a distal lower opening in fluid communication with the proximal upper opening, a middle portion disposed between the proximal upper opening and the distal lower opening, and a central axis extending from the proximal upper opening to the distal lower opening, the body at least partially tapering along a length of the body towards the distal lower opening, and the proximal portion being tapered radially inward towards the central axis relative to the middle portion; and
withdrawing the catheter proximally relative to the implantable artificial bronchus causing the the implantable artificial bronchus to unsheathe and naturally expand into an expanded state such that the implantable artificial bronchus remains disposed within the respiratory passageway,
wherein the implantable artificial bronchus being in the expanded state and disposed within the respiratory passageway results in at least a portion of the middle portion abutting an inner wall of the respiratory passageway and prevents the proximal upper opening from contacting the inner wall of the respiratory passageway.
