Material Notes:
ChronoFlex® AL is a family of premium polycarbonate aliphatic biodurable thermoplastic polyurethane elastomers developed by AdvanSource Biomaterials Corporation. ChronoFlex® AL medical-grade elastomers are manufactured under strict GMP conditions specifically synthesized to overcome the in vivo formation of stress-induced microfissures. Surface microfissuring is a major weakness of present polyurethane elastomers which may lead to catastrophic failures in long-term implanted devices. This makes ChronoFlex® AL an excellent material choice for medical device applications requiring long term durability.Information provided by AdvanSource Biomaterials Corporation.
