Abstract
An implantable catheter is provided that may be disinfected without removal from the body of a patient, using an electrochemical method to generate an electric field on the catheter surface and thus destroy microorganisms in a biofilm that is present or forming. A catheter system includes the implantable catheter and a voltage source that is operably connected to electrodes on or embedded in the exterior and optionally the interior catheter surface. Methods are also provided for disinfecting the implantable catheter in vivo and for detecting or confirming the presence of a pathogenic biofilm thereon.
