1. A catheter assembly, comprising:

  • a catheter adapter, wherein the catheter adapter comprises a proximal end, a distal end, a lumen extending therebetween, a side port connected to an extension tube, wherein a proximal end of the extension tube is configured to be connected to a fluid access device to allow fluid to flow into the catheter adapter through a fluid pathway, wherein the fluid pathway comprises the extension tube, a portion of the lumen distal to a septum, and a catheter;

    wherein a proximal end of the catheter is coupled to the distal end of the catheter adapter;

    the septum disposed in the lumen of the catheter adapter, wherein the septum prevents fluid in the fluid pathway from exiting the proximal end of the catheter adapter;

    a needle comprising a base, a tip, and a body extending therebetween, wherein the body of the needle is disposed within the lumen of the catheter adapter; and

    an antimicrobial lubricant applied to only a portion of an outer surface of the needle, wherein the portion of the outer surface extends from a distal portion of the needle to a distal end of the septum when the needle extends beyond the distal end of the catheter, wherein as the needle is withdrawn proximally through the septum, the septum removes the antimicrobial lubricant from the needle thereby depositing the antimicrobial lubricant on the distal end of the septum.
