A dual function medical pad is disclosed for both controlling patient
temperature and providing a patient-to-electrode interface. The pad
includes a fluid containing layer for containing a thermal exchange fluid
circulated therethrough, wherein the medical pad is operable for thermal
exchange with a patient through a first side of the fluid containing
layer. One or more electrodes are interconnected to the fluid containing
layer on the first side (e.g. electrosurgical return electrode(s), EKG
electrode(s), pacing/defribullation electrode(s)). Preferably, an
electrical connector is electrically connected to the electrode and
extends through the fluid containing layer to a second side thereof. Such
electrical connector is interconnected or selectively interconnectable to
a signal cable. The pad may further include an adhesive surface which
extends over at least a portion of the first side of the fluid containing
layer. Preferably, the adhesive surface substantially covers the
electrode(s). The adhesive surface may be defined by a conformable layer
that is thermally and electrically conductive. Such conformable layer may
comprise a first material suspended in a matrix defined by a second
material (e.g. a liquid suspended in a polymer matrix).
