Abstract
A stent including a hollow wire formed into a stent pattern. The hollow wire includes an outer member having an outer surface and an inner surface, a lumen extending longitudinally within the hollow wire, at least one opening extending from the outer surface of the outer member to the lumen, and a plurality of filaments extending longitudinally within the lumen. The plurality of filaments increases the amount of surface area available for tissue in-growth within the lumen. Each filament of the plurality of filaments is spaced from adjacent filaments of the plurality of filaments, and the spacing between adjacent filaments of the plurality of filaments is configured to permit tissue in-growth between the adjacent filaments.
