Material Enables Fabrication of Colored, High-Strength SuturesDSM, which created and manufactures Dyneema Purity, the world’s strongest medical grade fiber, offers Dyneema Purity BLUE, the first 100% colored implantable grade ultra high molecular weight polyethylene (UHMWPE) fiber. Dyneema Purity BLUE can be used in implantable applications to offer surgeons uncompromised strength, better contrast during arthroscopic surgeries, and differentiation between multiple sutures on multiple anchors.

Helping medical device companies develop new clinical approaches that can improve patient outcomes, Dyneema Purity BLUE can be used to develop a high strength suture alone or in combination with standard (white) Dyneema Purity without the need to use colored polyester or nylon strands in its construction. This offers surgeons uncompromised strength and color variety. In fact, several different patterns of braid can be developed to offer surgeons bright contrast among the different sutures, including various white/blue combinations, as well as solid blue.

Dyneema Purity BLUE maintains the same proprietary features of Dyneema Purity, including its maximum strength at 15 times stronger than quality steel while also offering a lower profile, softness, and abrasion resistance. Additionally, the fiber’s elongation and fatigue resistance offer a superior alternative to traditional materials for surgeons and medical device manufacturers. The blue UHMWPE fiber has good local tolerance according to ISO 10993:06. The fiber offers low irritation and low inflammatory levels when compared to other implantable materials, such as polyester, and has the same advanced biocompatibility as Dyneema Purity SGX, which has been in use in orthopedic sutures since 2004.
