| abstract |
The invention provides a medical material in which biocompatibility is provided to a substrate stably for over an extended period of time because of the ability of the material to reduce or prevent undesirable physiological properties inherent in the substrate, such as blood clotting, activation of complement system, platelet adhesion and the like. Such abilities are effected by the bonding of a fatty acid and/or its derivative to the substrate through a polymer. |
