Abstract
A stent is formed from a wire having an outer member, a radiopaque core member disposed within a portion of the outer member, and an annular lumen between the radiopaque core member and the outer member. A substance is disposed in the annular lumen to be eluted through at least one opening disposed through the outer member. A plurality of radiopaque core members are disposed within portions of the outer member and are separated by lumens defined by the inner surface of the outer member. The lumens and annular lumens are in fluid communication with each other. In a method for making the stent, a composite wire including an outer member, an intermediate member, and a core member is shaped into a stent pattern and processed to remove the intermediate member and portions of the radiopaque core member, without damaging the outer member.
