Abstract
An implantable endoluminal device that is fabricated from materials that present a blood or body fluid and tissue contact surface that has controlled heterogeneities in material constitution. An endoluminal stent-graft and web-stent that is made of an monolithic material deposited into a monolayer and etched into regions of structural members and web regions subtending interstitial regions between the structural members. An endoluminal graft is also provided which is made of a biocompatible metal or metal-like material. The endoluminal stent-graft is characterized by having controlled heterogeneities in the stent material along the blood flow surface of the stent and the method of fabricating the stent using vacuum deposition methods.

- 15. An endoluminal web-stent, comprising a generally tubular stent member comprised of a plurality of structural members separated by a plurality of interstitial regions, and a metal stent cover member subtending at least some of the plurality of interstitial regions, said metal stent cover member further comprising a continuous metal thin film fixed to at least one of the plurality of structural members and having a plurality of openings passing through the metal thin film and positioned in communication with the plurality of interstitial regions of the tubular stent member, the plurality of openings in the continuous metal thin film being smaller than the interstitial region of the tubular stent member adjacent the openings in the metal thin film.
- 18. An implantable medical device, comprising a metallic stent and a metallic stent cover, wherein the metallic stent comprises a plurality of structural members defining interstitial spaces between adjacent pairs of structural members and the metallic stent cover comprises a continuous tubular metal film that covers at least some of the plurality of structural members, is fixed to at least one of the plurality of structural members and has a plurality of openings passing through the metal thin film smaller than and adjacent to the interstitial spaces.
