Abstract
A wall, for example the wall of a vascular graft, has multiple channels within it. The channels may be used to hold drugs or reinforcing fibers. The channels may have a predetermined roughness. The channels may be formed by coextrusion using a soluble material, for example, to define the channels and then dissolving them to open the channels in the extrudate.
