Abstract
A method of forming a stent includes the steps of forming a composite member into a stent pattern, forming openings through an outer member of the composite member, processing the composite member to remove a portion of the composite member without adversely affecting the outer member, and swaging the outer member to create a plurality of lumens. The composite member may be formed of an outer member with an hourglass-shaped inner member, wherein the processing step removes the inner member and the swaging step forms two lumens from the hourglass shaped cavity. The composite member may be formed of an outer member, an inner member, and an intermediate member, wherein the processing step removes the intermediate member and the swaging step presses portions of the outer member into contact with the inner member to form two lumens separated by the inner member.
