1. A system for creating pericardial access into the pericardial space through the myocardium of the heart wall from a heart chamber accessed transvenously from a skin incision and for placing a medical device or fluid in the pericardial space comprising an elongated, tubular delivery device having a delivery device lumen extending from a delivery device proximal end to a delivery device distal end and a distal fixation mechanism at the delivery device distal end adapted to be advanced into the heart chamber and fixed to the heart wall at a selected site of the heart chamber;

  • an elongated pericardial access device having an access device distal tip adapted to perforate through the myocardium into the pericardial space upon advancement through the delivery device lumen; and

    a dilator having a dilator lumen extending between a dilator proximal end and a dilator distal end adapted to be advanced over the elongated pericardial access device and through the myocardium to form the pericardial access.
