摘要： An implantable device and method are disclosed for stenting an occlusion of an airway. The implantable device includes a cylindrical tube shaped proximal region, a flared distal region, and a non-bifurcated single lumen extending through the device. The proximal region defines a proximal portion of the lumen and the distal region defines a distal portion of the lumen. The distal region may flare outward laterally at a first angle and anteroposterior at a second angle, thereby forming an elliptically shaped distal opening to the lumen. The distal edge of distal opening may lie entirely in a plane orthogonal to a longitudinal axis of the device. Alternatively, the distal edge may be non-planar, such as concave or convex, when viewed in an anteroposterior direction. The implantable device may be formed of a scaffolding structure.
