ABSTRACT:
A synthetic vascular graft composed of fine denier polyester fiber forming a warp-knitted tube. The vascular graft has a porosity sufficient for optimum tissue ingrowth characteristics while at the same time retaining sufficient control of porosity to prevent hemorrhage at the time of implantation. The tubular vascular graft is knitted on a double needle bar warpknitting Raschel machine preferably with a tricot stitch and with the knitted structure having on the order of a 56 gauge.
