ABSTRACT:
A catheter or other invasive/implant device (40;52) 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 (48;53) to inhibit bacterial attachment and colonization on and adjacent the device/body interface. The generator can involve application to the device of electret material (53) or an electrode (48) in or for connection with 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.
