Hemocompatibility and cytocompatibility of TFE and X-OFP coated catheters, (A) human plasma coagulation time (B) platelet activation after blood contact with catheters for 1 h and 4 h, (C) hemolysis of red blood cells in blood incubated with catheters for 3h at 37°C, and (D) relative cell viability response to catheters as measured by MTT assay. A dashed line was drawn (70% viability) to indicate the reference line for cytotoxicity.
