1. A method for treating a patent foramen ovate, comprising:
- advancing a guidewire through the inferior vena cava, between the septum secundum and septum primum and into the left atrium of a patient;
advancing a treatment apparatus along the guidewire such that the distal end of a lumen of the apparatus is in proximity with the septum secundum; and
advancing a tissue-piercing member from within the lumen and through the septum secundum, wherein the tissue-piercing member is biased to deflect from a first, relatively straight configuration to a second, relatively curved configuration upon advancement from within the lumen.
