Abstract

See full text

A stent is formed from a wire having an outer member, a radiopaque member lining at least a portion of the outer member inner surface, and a lumen defined by the outer member inner surface or the radiopaque member inner surface. A substance is disposed in the lumen to be eluted through at least one opening disposed through the outer member to the lumen. The radiopaque member may be substantially continuous along the length of the wire or disposed only along portions of the wire such as crowns. In a method for making the stent, a composite wire including an outer member, a radiopaque intermediate member, and a core member is shaped into a stent pattern and processed to remove the core member and optionally portions of the radiopaque intermediate member, without damaging the outer member.
