1. A stent anchoring system for deployment in a lumen of a vessel, the system comprising:
- an expandable tubular member having a proximal end, a distal end, a longitudinal axis extending through the proximal and distal ends, an inner surface, an outer surface, a thickness between the inner surface and the outer surface, and a circumference in a plane perpendicular to the longitudinal axis; and
a plurality of surface protrusions extending outwardly from the outer surface of the expandable tubular member, the surface protrusions each having at least an outer surface, a first lateral surface and a second lateral surface, each surface protrusion spaced apart from a circumferentially adjacent surface protrusion,wherein the first lateral surface of the surface protrusion opposes the second lateral surface of the circumferentially adjacent surface protrusion, andwherein, upon deployment in the vessel lumen having a vessel wall, only the outer surface of each surface protrusion contacts the vessel wall.

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.
