Abstract

The subject of the invention is a method for the treatment of biomedical implants for the improvement of antithrombogenic properties thereof. The mentioned biomedical implants are cardiovascular implants, especially artificial blood vessels and stents made from a polyethyleneterephtalate (PET) polymer. The method is based on the treatment of a surface of cardiovascular implants by an adequate combination of a dose of neutral oxygen atom and positively charged molecular and atomic oxygen ions. After having been treated by a dose of said atoms and ions, the surface of cardiovascular implants becomes less prone to binding of thrombocytes. The method is characterised in that the exposure to a mixture of neutral oxygen atoms and positively charged molecular and atomic oxygen ions in pulses is such that in an individual pulse a dose of neutral oxygen atoms is reached between 1020 m-2 and 1026 m-2, and the dose of charged molecular and atomic oxygen ions between 1016 m-2 and 1023 m-2, the interval between individual pulses is between 10 s and 300 s, and that the flow of neutral oxygen atoms and positively charged molecular and atomic oxygen ions onto the surface of an implant is approximately even.
