[0058] An intravenous delivery system may have a plurality of components with interior surfaces that cooperate to define a fluid pathway through which fluid flows into a body of a patient. One or more anticoagulant coatings may reside on one or more of the interior surfaces to restrict blood clot formation in the fluid pathway. Manufacture of the intravenous delivery system may commence with provision of the components and preparation of an anticoagulant solution. The one or more interior surfaces may be exposed to the anticoagulant solution to form the anticoagulant coating. The anticoagulant coating may be caused to adhere to the one or more interior surfaces. The anticoagulant solution may be prepared by dissolving a triblock copolymer, such as PEO-PPO-PEO or PEO-PBD-PEO, in water. Irradiation may be applied to the anticoagulant coatings and interior surfaces to form covalent bonds.
