Abstract
A vascular graft comprising a traditional graft material and an electrospun fibrous layer. The solvent used to reduce the material for the electrospun layer is also capable of reducing the graft material to a liquid solution. The electrospun layer is chemically bonded to the graft material, without adhesives, by either spraying the graft with the solvent prior to electrospinning or by assuring that a sufficient amount of residual solvent reaches the graft while electrospinning.
