Abstract
A closure device for sealing a patent foramen ovale (PFO) in the heart includes a left atrial anchor adapted to be placed in a left atrium of the heart, a tether fixedly connected to the left atrial anchor and adapted to extend through the passageway of the PFO, a right atrial anchor adapted to be placed in a right atrium of the heart and moved along the tether, and a lock for securing the position of the right atrial anchor along the tether. The left and right atrial anchors preferably include a plurality of arms formed as loops and may include means for securing each arm in case of fracture in the loop. After the closure device is positioned, a cutting tool may sever the portion of the tether proximal of the right atrial anchor. The closure device can be retrieved during delivery, including by use of a snare catheter.
