Methods and apparatus for treatment of patent foramen ovale (PFO) generally involve use of a catheter having treatment means at its distal end. In some embodiments, the treatment means includes one or more retractable abrasive needles used to abrade tissue adjacent the PFO to induce closure of the PFO. In other embodiments, treatment means includes an energy transmission member or one or more apertures for dispensing a fluid to contact and close the PFO. An exemplary method involves advancing a catheter device to position the distal end adjacent the PFO, exposing a plurality of abrasive needles from the catheter, advancing the needles through the PFO and/or tissue adjacent the PFO, and retracting the needles relative to the PFO to abrade at least a portion of the tissue.

What is claimed is: 1. A method of treating a patent foramen ovale in a heart, the method comprising: advancing a closure device coupled with a distal end of a catheter device at least partway through the patent foramen ovale; releasing the closure device from the distal end of the catheter to induce closure of the patent foramen ovale without penetrating tissues adjacent the patent foramen ovale, wherein a portion of the released closure device disposed within the patent foramen ovale applies lateral force against tissues at opposite sides of the patent foramen ovale to bring tissue between the sides together, and deploying a staple to penetrate tissues adjacent the patent foramen ovale to seal the patent foramen ovale. 2. A method of treating a patent foramen ovale in a heart, the method comprising: advancing a closure device comprising flexible spring arms coupled with a distal end of a catheter device through tissue adjacent the patent foramen ovale; releasing the closure device from the distal end of the catheter to induce closure of the patent foramen ovale without penetrating tissues adjacent the patent foramen ovale, wherein the released closure device applies lateral force against tissues at opposite sides of the patent foramen ovale, apposing septum primum and septum secundum tissue of the patent foramen ovale to close the patent foramen ovale, and deploying a staple to penetrate tissues adjacent the patent foramen ovale to seal the patent foramen ovale. 3. A method as in claim 2, wherein the closure device is advanced through septum secundum tissue adjacent the patent foramen ovale. 4. A method as in claim 2, wherein the closure device is advanced through tissue of the atrial septum. 5. A method as in claim 4, wherein advancing the closure device comprises advancing the catheter device from a right atrium of the heart across the atrial septum to a left atrium of the heart. 6. A method as in claim 5, wherein advancing he closure device further comprises advancing the closure device from the left atrium of the heart into tissues of the patent foramen ovale. 7. A method as in claim 1, further comprising a pair of flexible spring arms, wherein the pair of arms are adapted to move apart from each other. 8. A method as in claim 7, further comprising a staple device coupled with the arms, such that the staple device is deployed when the arms move apart from each other. 9. A method as in claim 2, wherein the closure device is advanced through septum primum tissue adjacent the patent foramen ovale. 10. A method as in claim 2, further comprising a pair of flexible spring arms, wherein the pair of arms are adapted to move apart from each other. 11. A method as in claim 10, further comprising a staple device coupled with the arms, such that the staple device is deployed when the arms move apart from each other. 12. A method of treating a patent foramen ovale in a heart, the method comprising: advancing a closure device coupled with a distal end of a catheter device at least partway through the patent foramen ovale; releasing the closure device from the distal end of the catheter to induce closure of the patent foramen ovale without penetrating tissues adjacent the patent foramen ovale, wherein a portion of the released closure device disposed within the patent foramen ovale applies lateral force against tissues at opposite sides of the patent foramen ovale to bring tissue between the sides together, and deploying a non-penetrating clip adjacent the patent foramen ovale to seal the patent foramen ovale. 13. A method as in claim 12, further comprising a pair of flexible spring arms, wherein the pair of arms are adapted to move apart from each other. 14. A method as in claim 13, wherein said non-penetrating clip is deployed when the arms move apart from each other. 15. A method of treating a patent foramen ovale in a heart, the method comprising: advancing a closure device comprising flexible spring arms coupled with a distal end of a catheter device through tissue adjacent the patent foramen ovale; releasing the closure device from the distal end of the catheter to induce closure of the patent foramen ovale without penetrating tissues adjacent the patent foramen ovale, wherein the released closure device applies lateral force against tissues at opposite sides of the patent foramen ovale, apposing septum primum and septum secundum tissue of the patent foramen ovale to close the patent foramen ovale, and deploying a non-penetrating clip adjacent the patent foramen ovale to seal the patent foramen ovale. 16. A method as in claim 15, wherein the closure device is advanced through septum primum tissue adjacent the patent foramen ovale. 17. A method as in claim 15, wherein the closure device is advanced through septum secundum tissue adjacent the patent foramen ovale. 18. A method as in claim 15, wherein the closure device is advanced through tissue of the atrial septum. 19. A method as in claim 18, wherein advancing the closure device comprises advancing the catheter device from a right atrium of the heart across the atrial septum to a left atrium of the heart. 20. A method as in claim 18, wherein advancing the closure device further comprises advancing the closure device from the left atrium of the heart into tissues of the patent foramen ovale. 21. A method as in claim 15, further comprising a pair of flexible spring arms, wherein the pair of arms are adapted to move apart from each other. 22. A method as in claim 21, wherein said non-penetrating clip is deployed when the arms move apart from each other.
