Abstract
A method and apparatus for placing an epicardial lead over a desired, predetermined location on the left ventricle using a minimally invasive approach. A thoracoscope having a handle portion and a probe tube defining a central opening is placed through an incision in the patient generally aligned with the desired position for the pacing lead. An introducer and pacing lead are placed within the central opening of the thoracoscope and moved into contact with the pericardium at the desired lead location. An attachment member of the pacing lead attaches an electrode of the pacing lead to the pericardium. The pacing lead includes a mesh disk surrounding the electrode to aid in long term attachment of the electrode to the heart. Alternatively, the pericardium can be incised such that the lead is placed directly over the epicardial surface of the left ventricle.
