| 摘要 |
Biocompatible prostheses, specifically, biocompatible heart valves, are described which comprise a blend of a polyurethane (PU) and a polysiliconeurethane (PSU). Preferably, the polyurethane is a polyetherurethane (PEU). More preferably, it is a polyetherurethane urea (PEUU). Such prostheses typically exhibit reduced mineralization or thrombosis and/or reduced biological degradation.
