Abstract

A stent includes a hollow wire formed into a stent pattern. The hollow wire includes an outer member, a lumen extending longitudinally within the hollow wire, at least one opening extending from an outer surface of the outer member to the lumen, and a surface area component within the hollow wire. The surface area component increases the amount of surface area available for tissue in-growth within the hollow wire. More than one surface area component may be utilized. Each surface area component may be disposed within the lumen or the at least one opening of the hollow wire. A pharmacologically or biologically active agent may be disposed within the lumen.
