ABSTRACT:
An epicardial defibrillator lead which is placed into a paracardial space adjacent the phrenic nerve and is supported in position by the paracardium wall. A soft-nosed, rounded, blunt-nosed introducer provides for positioning of the defibrillator lead in the paracardial space. The electrode is formed on one side of a polymer member, which is conforming to the left ventricle and the paracardium wall. The electrode has a polymer backing to insulate the electrode from the paracardium wall. The electrode of the defibrillator lead conforms to the geometrical shape of the left ventricle.
