ABSTRACT:
The disclosure is that of an invention directed to new compositions of matter comprising a mixture of a resin in particulate form and colloidal graphite; and the use of such mixture to form objects of predetermined sizes and shapes, the exposed surfaces of which are strip treated and coated with a cationic surface active agent to make them Heparin-receptive, after which the objects are Heparin-coated to make them thrombo-resistant and non-thrombogenic.
