Devices, delivery systems and techniques for an occlusion device for the closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. The devices, delivery systems and techniques relate to, but are not limited to, a patent foramen ovale (PFO) occluder made from a substantially cylindrical form. An occluder having a distal side and a proximal side, with a catch system for securing the deployed configuration, is introduced into the treatment site by a delivery sheath. In one aspect, the occluder has an adjustable length center joint that allows the device to fit a particular septal defect. In some embodiments, the occluder includes a catch member that holds the occluder in the deployed, expanded profile configuration. In one aspect, the catch member also has an adjustable length.
