1. A method of forming a stent comprising the steps of:

  • utilizing a composite member including an outer member, an inner member disposed within a lumen of the outer member, and an intermediate member disposed between the outer member and the inner member;

    shaping the composite member into a stent pattern;

    forming openings through the outer member to the intermediate member;

    after the step of shaping the composite member into the stent pattern, processing the composite member such that the intermediate member is removed from the outer member without adversely affecting the outer member or the inner member, thereby leaving the outer member and the inner member with a cavity disposed therebetween; and

    swaging the outer member such that portions of the outer member are pressed into contact with the inner member, thereby deforming the outer member into an elliptical or oval shape to form a first lumen and a second lumen, the first and second lumens separated by the inner member and the portions of the outer member in contact with the inner member.
