An investigation into vascular prosthesis modified with an electron beam.
The present paper shows the results of an investigation into the effect of implanted electric charge on blood platelet adhesion to woven surfaces of "Dallon" polyester vascular prosthesis. The electrets were formed using the electron beam method. The assessment of the electret effect on blood platelet adhesion was performed on the basis of microscopic studies. It was shown that an implanted negative electric charge remarkably suppresses thrombocyte adhesion to the prosthesis surface. The electret effect was found to play a significant role in the process of preparing nonthrombogenic surfaces.
