Abstract
A method and apparatus for accessing the pericardial space is provided for stable short term or long term placement of a delivery catheter or cannula having its distal-most end fixed on the endocardial surface such that a pericardial access device including a dilator and a puncturing device may be advanced through the myocardium into the pericardial space. The catheter is provided with a distal fixation member that maintains the catheter position over the myocardial pericardial access created by the access device allowing various medical instruments to be passed through the pericardial access into the pericardial space. Alternatively, the catheter may be positioned against the septal wall to access a left heart chamber via a right heart chamber.
