Claim:
1. An airway stent, comprising: a proximal region having a cylindrical shape with a first opening at a proximal end, the first opening having a diameter equivalent to a diameter of the proximal region of the airway stent; a distal region extending from the proximal region to a second opening at a distal end, the distal region flaring outward such that the second opening has a transverse cross-section with an elliptical shape having a lateral diameter that is larger than an anteroposterior diameter, wherein a distal edge of the distal region includes a first notch at an anterior side and a second notch at a posterior side, wherein the first and second notches are configured to engage a cartilaginous ridge that runs anteroposteriorly between branches of an airway at a target bifurcation junction; and a non-bifurcated single lumen that extends from the first opening and through the proximal and distal regions to the second opening.
