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.

Abstract: A tissue splayer (76) is described which includes an index finger portion (4) and a middle finger portion (5). The tissue splayer also includes a first pivot joint (80) coupling the index finger portion (4) to the middle finger portion (5) to permit the middle finger portion (5) to rotate relative to the index finger portion (4) about a first pivot axis (81). The tissue splayer (76) also includes a first splay mechanism (88) configured to permit rotation of the middle finger portion (5) away from the index finger portion (4) about the first pivot axis, and to resist rotation of the middle finger portion (5) towards the index finger portion (4) about the first pivot axis (81).
