Abstract
A bi-polar cardiac lead for transmitting electric current to the heart and/or sensing and monitoring electrical activity of the heart has elongated electrical conductors connected to a head. The lead has a first electrode mounted on the head having a helical wire connected to one conductor adapted to be turned into heart tissue. The helical wire is coated with platinum black particles which decrease electrical losses at the electrode-tissue interface. A second annular electrode having an irregular outer surface configuration is mounted on the head around the first electrode. A plug impregnated with a drug is located within a recess in the head adjacent the electrodes. The drug migrates from the plug to the stimulation site.
