1. A reinforced graft particularly adapted for cardiovascular use, said graft comprising:

  • a tubular structure having a central lumen and comprising collagenous tissue having a generally tubular shape and a single monofilament wound in a coil with spacing between the turns of the coil to permit the tubular structure to be bent without crimping, the turns having "radial compliance", i.e., the turns going from one pitch to another pitch during bending, and said monofilament having a smaller single monofilament painted thereon in an overlapping manner to form a textured mesh-type surface with random interstices into which tissue can grow, said coiled monofilament being situated externally of said lumen.
