About AorTech
AorTech has developed biostable, implantable polymers, including Elast-Eon™ and ECSil™, now manufactured on its behalf by Biomerics LLC in Utah, USA. Elast-Eon™ and ECSil™'s biostability is comparable to silicone while exhibiting excellent mechanical, blood contacting and flex-fatigue properties. These polymers can be processed using conventional thermoplastic extrusion and moulding techniques. With over 6 million implants and over 10 years of successful clinical use, AorTech polymers are proven in long term life enabling applications.
In addition to continuing to exploit AorTech's Intellectual Property related to the world class biomaterial - Elast-Eon™, AorTech is now incorporating this material into a number of medical devices of our own design. Elast-Eon™ has first class long term blood contacting properties and, as a result, all of the initial products being developed are for the cardio vascular field. Each device is being designed to have improved clinical outcomes over current device technology, eliminating the use of animal sourced material whilst allowing procedures to remain the same, therefore avoiding having to retrain surgeons in new ways of operating.
