ABSTRACT:
A catheter assembly is described which comprises a catheter tube, an exterior portion of which is circumferentially surrounded by at least two parallel elongated helical conductive elements which may be operably connected to a first power source to create a first open circuit to induce an antimicrobial effect in the area proximate the exterior conductive elements through oligodynamic activity. The catheter assembly further comprises a hub at its proximal end having a cap containing a second power source. At least two internal conductive elements are disposed along the internal length of the hub and are operably connected to the second power source upon closure of the hub with the cap to create a second open circuit which creates an antimicrobial effect proximate the hub through oligodynamic activity.
