Abstract
Graft prostheses are woven with cross-weave patterns to prevent unravelling and to increase suture hold strength. A vascular graft according to the invention is woven as a continuous tube by shuttling a continuous weft thread through a double-layer array of warp threads. As the weft thread is shuttled through the warp pattern, groups of warp threads are retained in parallel relationship to each other while interspersed pairs of warp threads are crossed over each other. This results in graft having normal weave patterns circumferentially alternating with cross-weave patterns.
