Selective adherence of stent-graft coverings, mandrel and method of making stent-graft device

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 applying pressure.
