<p>A woven vascular graft having alternating plain/twill weave and two pairs of double leno weave is disclosed. Conventional knitted grafts are flexible soft and conforming, but require preclotting because the porosity is too great. Conventional woven grafts have low porosity and do not need preclotting but are stiffer and less conforming than knit grafts. The new vascular graft of this invention has low porosity as in other woven grafts, yet the pliability is similar to extruded grafts. The inventive weave pattern has fill threads (20), warp twill weave threads (23) and (25), plain warp threads (22) and (24), and two adjacent pairs of double leno threads (26), (27) and (28), (29).</p> |
