Abstract
A device closes septal openings, such as a patent foramen ovale (PFO). The device includes two anchors and a flexible connector. Tension applied to one or more strings attached to the device causes the device to collapse into a reduced profile form for withdrawal into a delivery catheter, thereby facilitating retrieval of the device after insertion into a septal opening.
