1. A medical device for puncturing a septum of a heart, the medical device comprising:
an elongate member including a wire, the elongate member having a proximal section, a distal section including an electrode, and a rail section between the proximal and distal sections;
the electrode operable to deliver energy to create a puncture through the septum; and
the rail section being configured to both act as a rail for supporting installation of one or more tubular members thereupon as well as to be maneuverable for enabling access to the septum;
wherein the distal section comprises a curved portion and a straight portion, the straight portion being distal to the curved portion;
wherein an outer diameter of the wire in the straight portion at a distal end of the straight portion is greater than an outer diameter of the wire in the curved portion at a distal end of the curved portion;
wherein the distal section is configured to automatically form a J-shape in a deployed state for anchoring the distal section being advanced through the puncture.
