Characterization of Polyurethanes for Blood-Contacting Applications
Segmented polyurethanes are widely used in commercial and experimental blood-contacting applications which include vascular prostheses, blood filters, catheters, insulation for pacemaker leads, heart valves, cardiac assist devices, and chambers for artificial hearts. The use of this family of polymers for such applications is due to the physiological acceptability, relatively good blood tolerability, relative stability over extended implant periods, and excellent physical and mechanical properties that are exhibited by these materials1.
