Abstract
An electrode system is provided for an implantable cardiac defibrillator. The electrode system includes a first endocardial lead having at least one electrode and a second epicardial or extrapericardial lead with an electrode that has a flexible configuration such that it is able to be straightened or compressed into an introducer but will expand when released from the introducer to provide a substantially larger surface area simulating the surface area of a patch electrode.
