1. An expandable medical device, comprising:
a tubular scaffold extending along a longitudinal axis, the tubular scaffold including an inner surface, an outer surface, a first end region, a second end region, a medial region positioned between the first end region and the second end region, and a lumen defined by the inner surface and extending from the first end region to the second end region within the tubular scaffold; and
a liner disposed within the lumen of the tubular scaffold;
wherein:
a first portion of the liner, extending fully circumferentially around the liner, is secured within and in direct contact with a first region of the inner surface of the tubular scaffold, thereby preventing tissue ingrowth with the first region of the inner surface of the tubular scaffold; and
a second portion of the liner, extending fully circumferentially around the liner, is not in direct contact with second regions of the inner surface of the tubular scaffold, thereby defining tissue ingrowth regions with respect to the second regions of the inner surface of the tubular scaffold and within the lumen.
