Abstract

A ravel-resistant, self-supporting woven synthetic fabric vascular graft including a fusible fiber integrated into the weave in the filling yarn is provided. The graft is woven from multifilament polyester warp yarns which can be textured or flat. The filling yarn includes a low melting fusible fiber or resin which can be combined with a stiff monofilament. The monofilament component provides radial rigidity to improve kink and crush resistance. After heat setting, the low melting fusible resin fuses to orthogonal warp yarns at each intersection and provides ravel resistance to the finished graft. Improved kink resistance make the tubular grafts suitable for use in medium and small diameter peripheral applications. A preferred graft has a single velour outer surface and a smooth inner surface.
