Abstract
An electrical lead for sensing electrical activity with the body of the patient and for applying electrical energization to selected body tissue comprises an elongated, flexible polymeric lead body having one or more conductors extending the length thereof, the conductors being connected at their distal end to electrode pads where the pads each comprise a multilayer thin metallic film structure formed on the surface of the lead body where the overall thickness of the composite electrodes are less than about 5 microns. As such, the electrodes do not adversely impact the ability of the distal end portion of the catheter to flex and conform to tissue structures where sensing is to be taken and therapy delivered via the lead.
