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.

Expandable thoracoscopic defibrillation catheter system and method

A hollow fiber blood oxygenator is provided having an plurality of enclosed, coaxial heat exchanger coils, having a common header to insure uniform temperature in the coils. An enclosed fiber bundle is concentrically positioned inside the heat exchanger coils to define a flow path around the coils and through the fiber bundle. The heat exchanger coils and the outside of the fiber bundle are tapered to provide a close fit. Gas manifolds direct gas flow to and from the hollow fibers.
