Abstract
The present invention provides a patent foramen ovale (PFO) closure clip. The clips of the present invention include two closure members joined by at least two spaced central connecting members. Each of the at least two spaced central connecting members is attached to each closure member at a location on the periphery of the closure member. The clips are designed such that the at least two central connecting members extend through the inclined PFO tunnel and the two closure members compress the overlapping layers of septal tissue, i.e. septum primum and septum secundum, together to close the PFO tunnel. The clips of the present invention take various forms depending, in part, upon the distribution of force required to close a given PFO. Thus, in some embodiments, the closure members include arcuate peaks. In other embodiments, the closure members include loops. In still other embodiments, the closure members include prongs.
