<p>A medical device, such as a catheter (10), for location at least partially within a patient's body for a period of at least the order of a day, includes an electrode (11) connected in an electrical circuit (11, 12, 13) operable to generate by way of the electrode an electric field to inhibit bacterial attachment and colonisation on and adjacent to the device/body interface, and the electrode includes an electrically conductive hydrogel coating (11) to define the device/body interface. The coating can be loaded with a salt to ensure conductivity and pH material to stabilise the surrounding hydrogen ion concentration in use of the device.</p> |
