Abstract
A cardiac lead for transmitting electric current to the heart and/or sensing and monitoring electrical activity of the heart has an elongated electrical conductor connected to a head. An electrode mounted on the head comprises a helical wire adapted to be turned into heart tissue. A second electrode having an irregular or non-flat surface surrounds the helical wire. The non-flat surface may be a wire mesh, a segmented plate and an annular plate supporting one or more coiled wires.
