Catheter tubing with extraluminal antimicrobial coating
First Claim
1. A method for applying an antimicrobial coating to catheter tubing in a pattern, the method comprising:
- applying an antimicrobial coating over an outer surface of catheter tubing; and
passing the catheter tubing through a die to remove a portion of the antimicrobial coating from the outer surface such that a pattern of antimicrobial coating remains on the outer surface after the catheter tubing has passed through the die.

Abstract
Various methods can be employed to apply an antimicrobial coating to the outer surface of catheter tubing. The antimicrobial coating minimizes the risk of microbe colonization on the outer surface of the catheter tubing when the catheter tubing is positioned within the vasculature of a patient. A catheter can be manufactured using a pre-treatment process which applies the antimicrobial coating to the catheter tubing prior to applying a lubricant over top of the coating. The lubricant can function to retain the coating on the outer surface and also to limit the diffusion of the antimicrobial agent from the coating. A catheter can include an antimicrobial coating that does not block the visibility of flashback. Because the antimicrobial coating can be minimally transparent, the coating can be applied to the outer surface in a striped pattern or other pattern that leaves a portion of the outer surface uncoated or minimally coated. The flashback will then remain visible through the portions of the catheter tubing where no coating or minimal coating is present.
