Abstract
A method is provided for puncturing a fossa ovalis of a heart, the method including inserting a catheter into a right atrium of the heart, and advancing a distal portion of the catheter toward an interatrial septum of the heart. A flexible longitudinal member is slid through openings disposed at the distal portion of the catheter, such that the flexible longitudinal member is made to loop around a portion of an inside perimeter of the fossa ovalis. While the flexible longitudinal member is looped around the portion of the inside perimeter of the fossa ovalis, a hole is punctured in the fossa ovalis at a puncturing point.
