ABSTRACT:
A method of treating recalcitrant indewelling catheter-associated infections including the following procedures: inserting into the lumen of the catheter, a primary electrode whose uninsulated distal section is of a spiral or filamentous configuration physically contacting the internal surface of the catheter; positioning and sealing a secondary electrode-receptacle on the skin area around the exit site of the catheter and around an external section of the catheter so as to form a conical container for holding liquids; infusion of a solution of antimicrobial drugs through the catheter; instilling a solution of antimicrobial drugs into the secondary electrode-receptacle; and applying a voltage differential between the primary and secondary electrodes, in which an electric field is applied to the internal and external surfaces of the catheter, and this field both disrupts hitherto priviledged sites for microorganisms on the surfaces of the catheter and drives antimicrobial drugs into these same surfaces.
