Abstract: The present invention relates to a method for grafting a surface of a medical device by using quaternized trimethylamine. A catheter onto which quaternized trimethylamine has been grafted allows for the reduction of thrombus production. Therefore, the catheter having quaternized trimethylamine grafted thereto exhibits the effect of repressing thrombus production and enhancing the function of inhibiting blood adsorption and blood cell adsorption.
