SURGICAL REPAIR PRODUCT COMPRISING UHMWPE FILAMENTS

摘要

The invention relates to an elongate surgical repair product such as a suture comprising a cable of which bending stiffness can be lowered, which fibrous member is a heat-set cable comprising at least 50 mass% of high-performance polyethylene yarn. The product shows very high tenacity, combined with a relatively high initial bending stiffness that is significantly reduced upon bending or flexing the member, without significant dimensional change; and allows both easy and well-controlled handling and good knot tying characteristics. The invention also relates to a method of making said elongate product, wherein UHMWPE filaments are subjected to heat treatment (pref . 140-151Grad C) under elongational tension.
