Abstract:
A method of making a bifurcated stent comprising the steps of:a) preparing a first expandable tubular member having a proximal end and a distal end and a longitudinal bore therethrough, said first tubular member provided with a branch aperture disposed between said proximal end and said distal end, said branch aperture communicating with said longitudinal bore and said aperture sized and adapted to receive and secure a second expandable tubular member;b) delivering said first expandable tubular member to a bifurcated vessel having a first lumen and a second lumen so that said first expandable member is disposed within said first lumen and said branch aperture communicates with said second lumen;c) expanding said first expandable member in an amount sufficient to secure said first expandable member in said first lumen;d) preparing a second expandable tubular member having a proximal end and a distal end having longitudinal bore therethrough;e) widening said branch aperture;f) delivering said second expandable tubular member into said branch aperture so that said distal end of said second expandable tubular member is disposed within said second lumen and said proximal end of said second expandable tubular member is disposed within said longitudinal bore of said first longitudinal member; andg) expanding said second expandable tubular member in an amount sufficient to secure said second expandable tubular member within said second lumen and within said branch aperture.
