A percutaneous access device is provided including a sleeve having an inner lumen extending therethrough that is adapted to slidably receive a catheter, and at least one flange disposed around the sleeve and adapted to be positioned adjacent a tissue surface. In a preferred embodiment, the device includes a first flange disposed around the sleeve and adapted to be positioned adjacent a first tissue surface, and a second flange disposed around the sleeve and spaced apart from the first flange such that the second flange is adapted to be disposed adjacent a second tissue surface opposed to the first tissue surface. In use, the flanges 16, 18 are positioned on opposed sides of tissue so that the device 10 is effective to prevent tissue surrounding the percutaneous access device from coming into contact with the catheter as it is introduced through the sleeve 12 . The device also includes an antimicrobial agent that is effective to protect against bacterial colonization on and around the access device, the catheter, and the tissue surface surrounding the access device.
