A self-contained, battery powered transseptal crossing system is disclosed. An elongate, flexible electrically conductive needle body has a proximal end and a distal end. An insulation layer surrounds the sidewall and leaves exposed a distal electrode tip. A generator is configured to deliver RF energy to the electrode tip, and includes a processor configured to take impedance measurements at the tip to confirm contact with the intra atrial septum and/or confirm entry into the left atrium.
