ABSTRACT:
The specification teaches thromboresistant compositions made of suitable biologically compatible plastic materials and a substance having a negative charge, e.g., graphite, incorporated therein in the framework of the lattices of the plastic, for use in prosthetic vascular devices intended to be permanently grafted in body loci wherein use of a thromboresistant prosthetic is desirable. An exemplary combination is polytetrafluoroethylene and graphite made into suitable structures for use as prosthetic arteries, veins and heart valves is taught.
