Abstract:
1. A method for performing a procedure at a fossa ovalis in a septal wall of a heart, the method comprising the steps of: providing a sheath comprising a body, the body having a lumen extending therethrough and an open end at a distal end of the body, the body also having at least one electrode and a position sensor at the distal end of the body, the position sensor generating signals indicative of a location of the distal end of the body; navigating the sheath to the septal wall using the position sensor; reconstructing an electroanatomical map using the at least one electrode and the position sensor of the sheath; identifying the fossa ovalis in the septal wall using the at least one electrode and the position sensor of the sheath; and displaying the fossa ovalis as a tagged point on the map.
