    摘要: Methods for coating a prosthetic surface with anti-thrombogenic, or anti-coagulant, proteins are disclosed. The methods involve contacting a surface of a prosthetic material with a composition containing multimers of fibrin degradation products. These multimers, preferably D-dimers, have cross-linked D-domains. The methods of the invention are useful for providing an anti-thrombogenic coating on prosthetic implants which are exposed to a patient's blood after implantation, for example vascular grafts and artificial heart valves.

    摘要: Surfaces of polymeric materials are coated with a layer of thermally denatured fibrinogen. The fibrinogen may be treated with thrombin to produce fibrin, and additional fibrinogen and factor XIII added to produce a cross-linked fibrin coating. The resulting coated surface is stable, anti-thrombotic and resistant to platelet adhesion. Polymeric materials coated in this way are useful in constructing vascular grafts and prosthetic devices, and provide test systems useful in the study of thrombogenesis.
