Abstract (en)

[origin: WO9831420A1] A catheter or other invasive/implant device (40) intended for relatively long term use, of the order of a day or more, in a patient's body is provided with an electric field generator to generate bactericidal H2O2 on and adjacent the device/body interface from available oxygen and water at a carbon cathode (48) connected in an electrical circuit (47, 50, 51). The field is preferably unidirectionally negative and also continuous and constant, but pulsatile, alternating and other field forms are possible. A surgical dressing may operate on the same principle.
