Concordia has experience with a broad range of absorbable and non-absorbable polymeric fibers suitable for medical implant applications. Extensive experience in the field of polymer science and strategic partnerships with medical fiber spinners make it possible for Concordia to offer an extensive portfolio of fiber materials that are well understood by the FDA and the surgeon community, and well tolerated by the human body based on biocompatibility data and decades of actual clinical implant experience.
Absorbable polymers include:
Non-absorbable polymers include:
Other materials:
Fibers can be extruded as either monofilament (a single filament) or multifilament (bundles of multiple filaments). Monofilament fiber diameters can be specified in mils or thousandths of an inch, while multifilaments are typically specified in denier or dtex. (Note: denier is the weight in grams of 9,000 meters of fiber, while dtex is the weight in grams of 10,000 meters of fiber). It is also possible to define filament size in microns typically based on measurements made of objects from SEM images. Alternatively, monofilaments and braided bundles of multifilament fiber can be referred to by United States Pharmacopeia (USP) size designations created for surgical sutures.
Concordia’s technical representatives will work with the customer to make sure the appropriate raw material, and optimum type and size fibers are used for the specific application.
