1. A method of forming a medical device comprising the steps of:
- utilizing a hollow wire having an outer member and a lumen of the outer member;
filling the lumen with a liquid to form a supported hollow wire;
shaping the supported hollow wire into a pattern;
forming openings through the outer member; and
after the step of shaping the supported hollow wire into the pattern, processing the supported hollow wire such that the liquid is removed from the lumen of the outer member without adversely affecting the outer member.

Abstract
A method of a forming a hollow, drug-eluting medical device includes utilizing a hollow wire having an outer member and a lumen of the outer member, and filling the lumen with a fluid to form a supported hollow wire. The supported hollow wire is shaped into a stent pattern. Openings are formed through the outer member. The supported hollow wire is processed to remove the fluid from the lumen of the outer member without adversely affecting the outer member, leaving the hollow wire shaped into a stent pattern. The lumen is filled with a biologically or pharmacologically active substance.
