  • Publication number: 20230277342
    Abstract: A vascular graft having a sealing layer and a tapered length portion. The sealing layer provides the vascular graft with low bleed characteristics subsequent to a needle puncture such as with a dialysis needle or a suture needle. The sealing layer in the tapered length portion has varying wall thickness along the tapered length portion.

  • Patent number: 11547548
    Abstract: A vascular graft incorporating a stent into a portion of its length. While various materials may be used for the vascular graft, the graft is preferably an ePTFE graft. The stent is preferably a self-expanding stent, although it may alternatively be a balloon expandable stent. The vascular graft preferably has a continuous inner tubular liner that extends between the opposing ends of the graft and provides a continuous luminal surface for blood contact that is uninterrupted by seams or joints. The length portion of the graft that does not include the stent has a greater wall thickness than does the portion including the stent.
