Material Notes:
A proven family of highly biocompatible medical grade polymers with outstanding physical and mechanical properties Bionate® PCU is a medical grade polymer for use in long-term implants. It has been used in chronically implanted medical devices for nearly two decades. The Bionate® PCU family is one of the most extensively tested families of biomedical polymers and is backed by a comprehensive FDA Master File. Both Bionate® PCU and Bionate® II PCU are tough, biostable and biocompatible polymers with exceptional performance characteristics. Widely Used The Bionate® PCU family is currently being used in a wide range of applications, including neurostimulation, vascular, artificial heart, cardiac assist and diagnostic devices. Because of its exceptional load-bearing capability and biostability, it is also used extensively in orthopedic applications such as hip and knee joints and spinal motion preservation devices. Due to its biostability, flexibility, electrical properties and tensile strength, the Bionate® PCU family is an excellent candidate for lead insulation. Tailor Made Bionate® PCU can be modified with SME® technology to incorporate end groups that can enhance device performance. Bionate® II PCU also offers a wide range of potential surface characteristics by using DSM’s patented SAME® technology. Summary of Product BenefitsBiostable and biocompatible Extensively tested Backed by a comprehensive FDA Master File In use for nearly two decades Exceptional abrasion resistance, flexibility and tensile strength Adaptable with SME® and SAME® technology Information provided by DSM Biomedical.
