  • Vascular graft with improved flow surfaces
    Patent number: 6517571
    Abstract: An ePTFE vascular graft having a smooth PTFE luminal surface which is substantially non-adhesive to occlusive blood components. Preferably the graft is a longitudinally extruded and expanded ePTFE tube of about 10-30 microns mean fibril length and is provided with a luminal surface covering of an ePTFE film of small mean fibril length (5 microns of less) which provides the smooth luminal PTFE surface. The graft is anticipated to be particularly effective as a small diameter graft (6 mm or smaller). It is anticipated to have utility as a conventional vascular graft, as a cardiovascular patch and as an intraluminal vascular graft and as a covering for stents.
