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.

14. A device for closing a defect in septal tissue, comprising:
-
a first side adapted to be disposed on one side of the septal tissue and a second side adapted to be disposed on the opposite side of the septal tissue, said first and second sides connected by at least one center joint, wherein each of said first and second sides includes an anchor member comprising a generally cylindrical member split along a central portion of a length of an outer circumferential wall of the generally cylindrical member to define a plurality of arcs that form an elongate oval therebetween, and wherein said first and second sides cooperate to provide a compressive force to the septal tissue surrounding the defect when said device is deployed at an intended delivery location. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
