Abstract: An endoprosthesis has an expanded state and a contracted state, the endoprosthesis includes a stent having an inner surface defining a lumen, having an outer surface, and defining a plurality of apertures through the outer surface, wherein the apertures are arranged in a micropattern; and a coating (e.g., polymeric coating) attached to the outer surface of the stent. The coating includes a base and a tissue engagement portion including a second surface facing outwardly from the stent, the tissue engagement portion including a structure that defines a plurality of holes extending inwardly from the second surface toward the base. The holes are arranged in a micropattern. When the endoprosthesis is expanded to the expanded state in a lumen defined by a vessel wall, the structure applies a force that may reduce stent migration by creating an interlock between the vessel wall and the endoprosthesis.

Abstract: A method for reducing mucus accumulation in an airway including disposing an implantable device within an airway, wherein the implantable device has a first end, a second end, and an inner surface defining a lumen extending from the first end to the second end; wherein at least a portion of the inner surface has a hydrophobic polymer coating thereon, wherein a polymer coating surface has dynamic water contact angles of 145 degrees or greater; and wherein the implantable device is constructed and arranged to maintain patency of the airway; wherein accumulation of mucus is reduced as compared to a similar implantable device without the hydrophobic portion of the inner surface. An implantable medical device having a superhydrophobic surface and a method of making an implantable medical device having a superhydrophobic surface are also provided. An implantable medical device having a micropatterned surface with enhanced adhesion to tissue, optionally in combination with other region(s) having a superhydrophobic surface and a method of making such a device. Methods and devices for prevention of bacterial adhesion to implanted medical devices.
