Abstract
The present invention provides devices for closing septal defects, such as a patent foramen ovale (PFO). The closure devices include a proximal anchor member, a distal anchor member, and at least one flexible center joint connecting the two anchor members. According to some embodiments, the proximal and/or distal anchor members may include a generally cylindrical member split along the central portion of its length to form an elongate oval. The proximal and/or distal anchor members may further include a tissue scaffold. At least some of the closure devices according to the present invention are repositionable and retrievable.
