Abstract
Provided is a covered endovascular stent-graft comprising a first membrana tectoria for modeling a vascular shape and a stent-graft skeleton fitted to the outside of the first membrana tectoria, at least part of the outer surface of the stent-graft skeleton being covered with a second membrana tectoria; the first membrana tectoria and the second membrana tectoria are combined so that at least part of the stent-graft skeleton is covered between the first membrana tectoria and the second membrana tectoria, wherein the first membrana tectoria and/or the second membrana tectoria is/are a polyvinylidene fluoride resin membrana tectoria. The polyvinylidene fluoride resin membrana tectoria of the covered endovascular stent-graft makes the cost reduced and has good mechanical properties and biological properties.
