摘要：
A method of making a multi-lumen stent graft includes covering a first mandrel that comprises a groove and a back wall of the groove with an innermost polymeric tube slitting the innermost polymeric tube along the back wall of the groove placing a second mandrel into the groove of the first mandrel and aligning the second mandrel with the back wall of the groove, deforming the innermost polymeric tube placing an outermost polymeric tube over the innermost polymeric tube and cutting an opening in the outermost polymeric tube over the second smaller mandrel, wherein the outermost polymeric tube and innermost polymeric tube comprise a graft member.
