  • Vascular prosthesis and method
    Patent number: 5246451
    Abstract: A vascular graft with improved endothelial cell adhesion can be achieved on a fluoropolymer surface of a vascular graft by treating the fluoropolymer with a plasma in the presence of a non-polymerizing gas capable of providing the fluoropolymer with anionic groups and binding a protein to the treated fluoropolymer. In a preferred embodiment, the fluoropolymer surface is a plasma deposited fluoropolymer. Also in a preferred embodiment, autologous endothelial cells are seeded onto the vascular graft prior to implantation of the vascular graft in the human body.
