An electrical sensing/stimulation apparatus may comprise an elongate lead body having at least one internal lumen, at least one sensing/stimulation electrode, a deployable/retractable displacement member that moves or biases at least one electrode towards a prescribed direction by the user, a tissue attachment mechanism for affixing the distal segment of the device to body tissue, and an atraumatic distal lead body termination. In a retracted configuration, the attachment mechanism is positioned substantially within the distal segment of the lead body, and in the deployed configuration, the attachment mechanism extends from the axis of the lead body to engage body tissue.
