Abstract:
1. A method of measuring a characteristic of a patent foramen ovale defining an axis oriented axially through the patent foramen ovale, the method comprising: extending a distal end of a catheter having a longitudinal length into the patent foramen ovale so that the catheter is oriented longitudinally to be substantially parallel to, or extending substantially along, the axis of the hole; positioning a first atrial anchor in the left atrium of a heart; positioning a second atrial anchor in the right atrium of the heart; releasing a detectable substance directly in the patent foramen ovale from a location between the first atrial anchor and the second atrial anchor and from a port defined in the catheter located proximal the distal end of the catheter; and detecting the location of the said detectable substance in the heart.
