Material Notes:
The flex life exhibited by BioSpan® SPU enables good performance in many different types of medical devices. This elastomeric polymer has shown the ability to withstand millions of flex cycles.The combination of properties inspires exceptional devices In addition to excellent flex life, BioSpan® SPU offers a combination of additional properties, including low modulus, high tensile strength, high elongation, proven biocompatibility and good biostability. Because of these properties, it is used in ventricular assist devices as well as in artificial hearts, interventional cardiology balloons, drug eluting stents and spinal implants. Tailor Made BioSpan® SPU can be enhanced with SME® technology to incorporate different surface active end groups such as silicone and fluorocarbon. SME® technology eliminates the need for additional surface modification steps after the device component is fabricated.Summary of Product Benefits Excellent flex life Outstanding mechanical strength Hydrolytically stable Extremely elastic Biocompatible Adaptable with SME® technology Comprehensive FDA Master File Information provided by DSM Biomedical.
