Abstract
Devices, delivery systems and delivery 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 delivery techniques relate particularly to, but are not limited to, a patent foramen ovale (PFO) occluder made from a polymer tube. In certain embodiments, the occluder includes a catch system that holds the occluder in the deployed, expanded profile. The catch system includes a locking funnel cap. In some embodiments, the locking funnel cap forces the proximal ends of the occluder in a radially inward position to lock the catch member in place and prevent the occluder from moving from its deployed configuration.
