Abstract
An antimicrobial composition, generally comprising a biocidal agent, such as chlorhexidine gluconate, a lubricant, such as a modified siloxane, and a solvent, such as an alcohol and/or water. The biocidal agent acts as a highly effective biocide while the lubricant reduces friction between various components of a medical device during assembly. The antimicrobial composition may be applied to an internal component of the medical device prior to assembly. The process of assembling the medical device results in antimicrobial composition being distributed to various internal structures and geometries of the medical device as the coated, internal component is assembled into the interior of the medical device. Air is then used to further distribute excess antimicrobial agent to the remaining surfaces downstream from the installed, internal component. In some embodiments, additional air is passed through the assembled medical device to assist in removing the carrier solvent from the medical device via evaporation.

11. A method for assembling a medical device, comprising:
-
providing a medical device having an internal lumen; providing a septum having an outer surface; coating the outer surface of the septum with an excess of an antimicrobial compound, the antimicrobial compound comprising; a non-alcohol, biocidal agent; a lubricant; and a carrier solvent comprising an alcohol, the carrier solvent being capable of dissolving the biocidal agent and the lubricant; inserting the coated septum into the internal lumen of the medical device; distributing the excess antimicrobial compound to the internal lumen by advancing and seating the coated septum within the internal lumen; further distributing the excess antimicrobial compound within the internal lumen by blowing air through the internal lumen and the seated septum; and blowing additional air through the internal lumen and the seated septum to evaporate the carrier solvent of the antimicrobial compound thereby immobilizing the lubricant and the non-alcohol, biocidal agent within the internal lumen. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An antimicrobial composition, comprising:
-
a non-alcohol, biocidal agent comprising chlorhexidine gluconate, wherein the chlorhexidine gluconate comprises about 0.01% to about 0.5% of the antimicrobial composition, by weight; a lubricant comprising a low viscosity siloxane; and a carrier solvent comprising an alcohol, the carrier solvent being capable of dissolving the biocidal agent and the lubricant, the alcohol comprising a mixture of isopropanol and ethanol in a ration from about 1;
10 to about 1;
