Abstract
A luminal endovascular graft or endoprosthesis having a tubular support which expands between a first diameter and a second, larger diameter is provided with an expandable porous coating which is applied over either or both of the internal cylindrical surface and the external cylindrical surface of the tubular support. The first diameter allows the introduction of the luminal endoprosthesis into human or animal body passages. The expandable coating preferably is made from biocompatible fibers formed into a structure which allows normal cellular invasion upon implantation, without stenosis or restenosis, when the support element is at its second diameter.
