Derivatized polyurethane compositions which exhibit enhanced stability in biological systems and methods of making the same

   
   

The invention relates to methods of making polyurethane derivatives which can be readily further derivatized using stabilizing agents such as anti-calcification agents, anti-thrombogenesis agents, and chemical and mechanical degradation-inhibiting agents. The invention also includes methods of making polyurethane derivatives so further derivatized and to polyurethanes derivatives made using such methods.

L'invention concerne des méthodes de les dérivés de polyuréthane de fabrication qui peuvent être les agents stabilisants employants dérivatisés aisément encore tels que des agents d'anti-calcification, des agents d'anti-thrombogenesis, et des agents dégradation-empêchants chimiques et mécaniques. L'invention inclut également des méthodes de la fabrication de de dérivatisation tellement encore de dérivés de polyuréthane et aux dérivés de polyuréthanes faits en utilisant de telles méthodes.
