ABSTRACT:
An implantable cardiac stimulation system having a patient warning system and an elongated electrode mounted near the can of the system for providing reliable stimulation for warning. The electrode has an extended length and a short width. The length is preferably at least double the width and more preferably at least four times the width. This extended length increases the probability that contact with the surrounding tissue will be achieved. The short width and rounded profile of the width, forming an "edge", on the other hand, increases the probability that a high enough current density will be achieved, causing stimulation to occur. The electrode may also be curved along its length, which tends to promote a "point" or small area contact between the electrode and the patient's tissue. The electrode may be mounted directly on the can or header of the cardiac stimulator or may be part of a separate pin electrode. If a pin electrode is used, a hood configuration can be used to surround at least part of the header, reducing rotation of the pin electrode. By making only a portion of the surface of the pin electrode conductive, and particularly edges or corners, an elongated electrode, as described herein, is formed which produces a higher electric current density and more efficient stimulation.
