Abstract
Methods and apparatus for thoracoscopic defibrillation of a patient's heart. The technique involves introducing a first electrode (10) through a percutaneous intercostal penetration, positioning the first electrode against the heart surface (H) and positioning a second electrode (10') against the patient's body. A voltage is then applied through the percutaneous intercostal penetration to the first electrode and to a second electrode to deliver electrical energy to the first electrode, through at least a portion of the patient's heart, and to the second electrode. The electrical energy applies an electric charge to the patient's heart to defibrillate the heart muscle or restart the heart during, for example, cardiac procedures that involve arresting the heart.
