Abstract
A method and system for positioning a defibrillation electrode about the heart includes means for placing the electrode in contact with epicardial or pericardial tissue from an inferior vena cava (IVC) access site. A small hole is made in the IVC at the selected access site. A defibrillation lead having the defibrillation electrode near its distal end is transvenously inserted through the IVC and out through the small hole into a chest cavity adjacent the heart. The electrode is then positioned so as to contact the desired cardiac tissue. If pericardial contact is to be made, the distal end of the lead, including the electrode, is looped around the pericardium. If epicardial contact is to be made, an additional small hole is made in the pericardium, and the distal end of the lead, including the electrode, is inserted through the additional hole into the pericardial space, and the electrode is positioned to contact the desired epicardial tissue.
