TECHNOLOGY Researchers at Cambridge Polymer Group and the Massachusetts General Hospital have developed a novel and highly crosslinked ultra high molecular weight polyethylenes that incorporate Vitamin E. Our research results indicate that these new UHMWPEs exhibit lower wear than conventional UHMWPE by a factor of 5 to 10, better mechanical properties by over 30% compared to first generation highly crosslinked UHMWPE, and are highly resistant to oxidation. APPLICATIONS The E-CIMA technology can be used as liners for hip, knee, shoulder, and spine arthroplasty implants. ADVANTAGES - The technology have already received CE marking, and are patented and patent pending with worldwide coverage. - These new UHMWPEs exhibit lower wear than conventional UHMWPE by a factor of 5 to 10. - Better mechanical properties by over 30% compared to first generation highly crosslinked UHMWPE, and are highly resistant to oxidation. - Improve wear and fatigue resistance by 130% compared to irradiated and melted Ultra High Molecular Weight Polyethylene (UHMWPE). - The technologies have received CE marking, and are patented and patent pending with worldwide coverage. - Protected against adhesive/abrasive wear, delamination and risk of cracking or fracture under normal and adverse conditions. - The vitamin E reservoir feature enables the continuous redistribution of vitamin E to the surface, thereby maintaining the integrity of the entire implant component. - Prolong the life of the implants and lesson the chances of additional implant replacements
