摘要： The present invention provides devices and methods for closing a physical anomaly comprising two overlapping layers of tissue, such as a patent foramen ovale ("PFO"). A PFO is comprised of two overlapping layers of malformed interatrial septa, the septum primum and the septum secundum, that form a tunnel between the right atrium and the left atrium. The closure device includes two wings connected to a central arm. The device is delivered through the PFO tunnel in a substantially linear configuration such that the central arm is seated within the PFO tunnel, the first wing extends into the right atrium, and the second wing extends into the left atrium. Once implanted, the closure device is reconfigured such that the arm is seated within the PFO tunnel, the first wing folds against the septum secundum, and the second wing folds against the septum primum, thereby sealing the defect.
