Abstract
Methods and apparatus for treatment of layered tissue defects having a majority of the surfaces of the defect layers in contact generally involve use of a catheter having at least one energy transmission member at its distal end. The distal end of the apparatus also typically has a force applying member which can apply a force to the tissue defect. Often this force is a lateral force or vacuum which helps the tissue to appose itself. An exemplary method of closing a patent foramen ovale (PFO) involves positioning a closure device between layers of the PFO. Energy is then applied to the layered tissue defect with the closure device so as to substantially close the tissue defect. The energy is often monopolar or bipolar radiofrequency energy. A force may also be applied by the closure device to the layered tissue defect so as to bring the layered tissue defect together.
