Abstract
A tracheal stent is an expandable tubular member having a proximal end, a distal end, an inner surface, and an outer surface. Circumferentially adjacent surface protrusions extend outwardly from the outer surface of the expandable tubular member. These surface protrusions have an outer surface, a first lateral surface and a second lateral surface. When the tracheal stent is deployed, the outer surface of the surface protrusion applies a radial force to a wall of the trachea to remove an airway constriction.
