Abstract
An epicardial lead having an electrode extending from the bottom thereof in combination with an anchoring system adapted to secure the lead to the heart without the use of complex procedures or tools. In a preferred embodiment the epicardial lead comprises an electrode body having two oppositely disposed arms, each arm fixed for rotation, each arm having an arcuate anchor mounted to the bottom surface, each arcuate anchor having as the center of the arcuate shape the axis of rotation of the respective arm. Rotating the arms causes each arcuate anchor to move in a circular fashion such that when each arm is moved from an open position to a closed position the respective anchor is moved to engage and move through the cardiac tissue and thereby secure the lead to the heart.
