Abstract
A method of making an implantable medical device includes extruding a first ePTFE tube and a second ePTFE tube, cutting a plurality of slits in the first ePTFE tube, positioning a radially expandable support layer between the first and second ePTFE tubes so that the slits span portions of the support layer, and laminating the first ePTFE tube to the second ePTFE tube through openings in the support layer.
