Abstract
A high strength suture is made from a LCP/polyester composite of braided filaments having a high coefficient of friction. Knots tied in a suture made from such braided filaments have a tendency to stay in place better than the prior art UHMWPE/polyester composite knots. The inventive suture may include a multifilament cover of fibers of LCP and/or LCP composite fibers. Where a core is employed, the core may be made up of twisted fibers of LCP and liquid crystal composite fibers. If desired, the composite fibers can be a combination of LCP and other polymers such as polyester, nylon, fluoropolymers such as FEP or PTFE or olefins such as polypropylene, polyethylene or UHMWPE. A low friction coating, such as silicone, may be applied over the outside surfaces of the suture.
