Solvay Advanced Polymers unveil stock shapes of Zeniva™ PEEK for implantable medical devices

Solvay Advanced Polymers, LLC, has launched a range of stock shapes made of Zeniva PEEK (polyetheretherketone), one of four polymers that comprise the company's family of Solviva™ Biomaterials being offered for use in implantable medical devices. The company made the announcement at the 2009 annual meeting of the American Academy of Orthopaedic Surgeons (AAOS) this week in Las Vegas, Nevada. According to the company, Stock shapes made of Zeniva™ PEEK offers broad chemical resistance, high strength and stiffness, excellent toughness, and fatigue resistance. They are said to be ideally suited for close tolerance machining of finished components and for prototypes used in injection molding applications. Typical applications include spinal implants, pacemaker components, and cardiovascular connectors. Zeniva™ PEEK resin and stock shapes comply with ISO 13485 manufacturing and meet current Good Manufacturing Practices (GMP). Based on rigorous biocompatibility testing, these products demonstrate no evidence of cytotoxicity, sensitization, irritation, or acute systemic toxicity as defined by ISO 10993. These materials can be sterilized using all conventional methods, including gamma radiation, ethylene oxide, and steam. In addition to Zeniva™ PEEK, Solviva™ Biomaterials include Proniva™ self-reinforced polyphenylene, Veriva™ polyphenylsulfone, and Eviva™ polysulfone. These biomaterials are offered for use in implantable devices for short-term and long-term use.
