摘要： In some embodiments, a method includes a shaft having a side catheter guide attached thereto via a guide coupler into an inferior vena cava and a superior vena cava such that the guide coupler is disposed in a right atrium, and applying a distal force to a proximal portion of the side catheter guide such that a distal end of the side catheter guide deflects laterally about the guide coupler towards a septum. The method further includes extending a side catheter that is disposed within the side catheter guide distally from the side catheter guide towards and into contact with the septum. The method further includes, with the side catheter in contact with the septum, extending a septum penetrator that is slidably disposed within the side catheter distally from the side catheter such that the septum penetrator pierces the septum.
