Antimicrobial compositions finding particular utility for coating access systems, lead devices including shunts, cannulae, catheters, catheter adapters, wires and other solid or hollow tubular devices used for a variety of medical purposes is provided. The composition comprises a material selected from the group consisting of acrylonitrile-butadiene-styrene copolymers, polyvinyl chloride, mixtures thereof, polyesters, polyurethanes, styrene-block copolymers, natural and synthetic rubbers, polycarbonates, nylon and silicone rubber mixed with an oligodynamic material consisting essentially of compounds of physiological, antimicrobial metals.

An antimicrobial composition comprising: 30 to 85 percent by weight of a binder consisting essentially of a material selected from the group consisting of acrylonitrile-butadiene-styrene copolymers, polyvinyl chloride, mixtures thereof, polyesters polyurethanes, styrene-block copolymers, natural and synthetic rubbers, polycarbonates, nylon and silicone rubber; and 15 to 70 percent by weight of an antimicrobial agent selected from the group consisting of compounds of antimicrobial metals and mixtures thereof that are physiologically compatible with human tissue, said binder having a sufficiently low dielectric constant so as to allow said antimicrobial agent to form a chain-like structure to create an initial dose of antimicrobial action upon first use by allowing antimicrobial ions on a surface of said composition to dissolve, said chain-like structure providing a pathway in said binder to allow interior antimicrobial ions in said composition to come to said surface of said composition to provide subsequent doses of antimicrobial action.
