1. An implantable antibacterial barrier device for an elongated medical device, the elongated medical device configured to extend from a first site, through a second site, to a third site, the implantable antibacterial barrier device comprising:
a housing configured to be disposed at the first site, the housing comprising barrier circuitry;
a working electrode configured to be disposed at the second site, the working electrode electrically coupled to the barrier circuitry; and
a reference electrode configured to be disposed at the first site and spaced apart from the working electrode, the reference electrode electrically coupled to the barrier circuitry, the barrier circuitry configured to selectively maintain the working electrode at a negative electrical potential relative to the reference electrode to form an antibacterial barrier.
