Abstract:
A method of a forming a hollow, drug-eluting nitinol stent includes shaping a composite wire into a stent pattern, wherein the composite wire includes an inner member, a nitinol intermediate member, and an outer member. After the composite wire is shaped into the stent pattern, the composite wire is heat treated to set the nitinol intermediate member in the stent pattern. After heat treatment, the composite wire is processed to remove the outer member and the inner member without adversely affecting the intermediate member. Openings may be provided through the intermediate member and the lumen of the intermediate member may be filled with a substance to be eluted through the openings.
