ABSTRACT:
An improved implantable pacer lead separates the pacing function and sensing function to the benefit of both pacing threshold and sensing effectiveness. Such separation permits the reduction of the size of the necrotic capsule that forms around the pacing electrode and also permits the use of smaller pacing electrodes which stimulate smaller regions, and therefore require less energy. The separation also permits the use of materials that concentrate the pacing energy where it is needed. The separation further works to the benefit of the sensing function because the sensing electrode may be placed exactly where it is most effective, independent of the optimal pacing electrode position. Similarly the size, shape, material and surface characteristics of the sensing electrode may be optimized irrespective of the pacing electrode.
