Abstract: A conductive member such as conductive pad (1) for use in radiofrequency ablation, the conductive member being flexible so as to conform to a subject's skin, the conductive member comprising a conductive skin contact layer (5) arranged for contact with the subject's skin and a conductive layer (4) over the conductive skin contact layer, in which the conductive skin contact layer (5) and the conductive layer (4) are both conductive to DC electrical signals.
