100% colored implantable UHMWPE fiber for medical-grade applications

27-May-10

Dyneema Purity® Blue, the first 100% colored implantable ultra high molecular weight polyethylene (UHMWPE) fiber for medical-grade applications has been introduced by DSM Dyneema. The fiber, which features the original Dyneema Purity®'s strength, softness and abrasion-resistance properties, offers improved contrast for implantation through arthroscopic surgeries and differentiation among multiple sutures on multiple anchors. The new material may be used alone or in combination with standard white Dyneema Purity to develop a high-strength suture. Several braid patterns can be developed to provide bright contrast among different sutures, including solid blue and white/blue combinations. The fiber offers good elongation and fatigue resistance compared with traditional materials; low irritation and inflammatory levels when compared with implantable materials such as polyester; and offers advanced biocompatibility comparable to that of Dyneema Purity® SGX, which has been used in orthopedic sutures since 2004.
