ABSTRACT:
A double-velour vascular graft has a tubular body or trellis with loops projecting both outwardly and inwardly from said trellis. The loops on both the inner and outer surfaces of the trellis provide for more effective preclotting and ingrowth of tissue without impeding the flow of blood through the tubular body. The graft is produced on a double-needle bar warp-knitting machine using two outside beams and two inside beams, the beams feeding yarn for the loops to said knitting machine at a greater rate than the beams feeding yarn for the trellis.
