The innovative components of the PFO Closure Device are elliptical envelopes rotating around an eccentric axis. Although sharing the same axis the envelopes can be rotated relative to one-another allowing for a broad range of septal defects to be occluded. During deployment the envelopes are rotated individually via a novel catheter until complete closure is achieved; once accomplished, the envelopes are locked together, via counter clamping, ensuring the successful occlusion of the septal defect. The device has a low profile therefore reducing the need for oversized delivery mechanisms.
