Abstract
An epicardial lead with an insertion assembly for attaching same into good stimulating contact with the heart wall, the lead having movable fixation means for fixing the distal electrode head to the heart wall in combination with a stimulating probe electrode for delivering stimulus signals to the heart. The fixation element is preferably of a corkscrew configuration, oriented normal to the lead axis, and is normally contained within an enclosed electrode chamber. The insertion assembly provides means for releasably holding the electrode head while screwing the fixation member into the epicardial wall. Since the fixation member is free to move with respect to the electrode head, the lead can remain free to be hooked to an external pacer during the fixation step. In operation, a separate stimulus probe is inserted in at various points of the epicardium for testing of threshold and when a good threshold is attained, the lead is then fixed to the heart by screwing the fixation member while maintaining the probe electrode in its desired position.
