    摘要： The present invention relates to a method of making a laminated expandable polytetrafluoroethylene (PTFE) elongated member that is radially expandable to at least 7 times its unexpanded diameter by a pressure of less than 6 atmospheres, the method comprising the steps of: selecting a PTFE material with an average molecular weight of about 120 million and an average particle size in a range of from about 350 to about 759 microns (µm); providing a mixture of the PTFE and a lubricant; compressing the mixture to form a compressed extrusion billet; extruding the billet as extruded strands; forming the extruded strands into tube lengths; expanding each tube length at a strain rate in a range of from about 10 %/sec to 200%/sec; contacting each tube length with at least one other unsintered elongate PTFE extrusion that has a different diameter from said tube length to form nesting elongated members; and sintering the nested elongated members.

    摘要： A method of making an endoluminal stent-graft, comprises the steps of:
    placing a first covering member composed of a boicompatible polymer on a surface;
    placing a radially expandable stent over said first covering member;
    laying down a layer of an activatable adhesive material over the first covering member and the stent;
    placing a second covering member composed of a biocompatible polymer over the stent; and
    inscribing a pattern of electromagnetic energy on the stent-graft to activate the adhesive forming a pattern of bonds between the covering members which bonds corresponds to the pattern of electromagnetic energy and which bonds allow portions of the stent to move freely when the stent expands.
