Abstract

An example medical device is disclosed as an expandable stent. The stent includes a tubular scaffold having an inner surface, an outer surface, and a lumen extending therein. The expandable stent also includes a liner disposed within the lumen of the tubular scaffold. Further, the liner is radially spaced from a medial region of the tubular scaffold to define a tissue ingrowth region along an uncovered portion of the medial region. Additionally, the liner extending along the tissue ingrowth region is configured to limit the amount of tissue ingrowth along the medial region of the scaffold.
