WBC posters, forums highlights increasing adoption of PEEK-OPTIMA polymers across medical and surgical applications.

THORNTON-CLEVELEYS, UK (June 9, 2008) -- Invibio® Biomaterial Solutions, a worldwide leading provider of high-performance implantable biomaterials to the surgical and medical device markets, (including PEEK-OPTIMA® polymer and compounds and ENDOLIGN® composite) announced that it posted original research data at the 8th World Biomaterials Congress (WBC), May 28 through June 1 at the RAI International Convention Centre in Amsterdam, The Netherlands.

Available to the medical device community for almost a decade, PEEK-OPTIMA is recognized as both the flagship and market-leading high-performance implantable polymer. Invibio presented two posters exploring preliminary evaluations of new forms of PEEK-OPTIMA (porous and fiber) that may enhance tissue interaction and integration, which were conducted in collaboration with the School of Chemical, Biological, and Materials Engineering, University of Oklahoma.

Additionally, Invibio hosted two Congress forums, "Biomaterial Surface Interactions and the Versatility of PEEK" and "The Tribology of PEEK Polymer: Promising Results for Bearing Applications." Presenters at the forums included Prof. Geoff Richards (AO Research Institute), Dr. Susan Scholes, Ph.D (Durham University) and Dr. Steven M. Kurtz (Drexel University), all of who are recognized experts in their fields.

Every four years, WBC addresses clinical and medical development and application trends and issues across the global materials science, bioengineering, biotechnology and tissue engineering continuum; this year, 2,300+ scientists, medical professionals and manufacturers from the medical device and pharmaceutical industries attended. Reflecting the trend toward PEEK polymers and compounds in applications previously dominated by ceramics, metals, bone and other polymers, more than a dozen papers and presentations focusing on PEEK biomaterials were offered. Topics included: wear performance of PEEK-OPTIMA materials in screening tests and in spinal and knee arthroplasty; laser welding of PEEK-OPTIMA for medical devices; polymer solutions for radiology treatment improvements; tensile fracture behaviour in the presence of a Notch Riser; PEEK vs. titanium potential for bone formation of human primary osteoblasts; surface modification of PEEK using oxygen plasma treatment to aid cell growth response; and effects of hydroxyapatite coatings on PEEK and carbon fiber-reinforced PEEK properties.

According to Invibio president Michael Callahan, PEEK-OPTIMA polymer and compounds have been outperforming competitive implantable medical device materials since its introduction in 1999. This proven track record, he reports, coupled with the continually evolving body of recent clinical data and research confirming its application-specific suitability, has boosted the versatile polymer to a prominence across an increasingly diverse range of applications.

"Clearly, PEEK polymers are enabling innovation and advancement in numerous new areas that, hopefully, will lead to improved patient care and clinical outcomes; this strong and steady trend shows no signs of abating and new and promising applications are emerging every day. The field of spine implant design is just one example; PEEK-OPTIMA is now broadly accepted as a high-performing and versatile alternative to metallic, ceramic and other biomaterials across the spinal fusion community and is used in the development of novel motion preservation and dynamic stabilization applications, " Callahan commented. "Additionally," added Callahan, "PEEK-OPTIMA has gained acceptance in a wide range of non-spine markets including arthroscopy, dental, pharmaceutical, cardiovascular and orthopaedics."
