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. The securement systems enable the deployment (and retrieval) of the device. In one aspect, the second securement system employs a snare connection. The snare connection may have various configurations, including a single snare, double snare, and double criss-cross snare. The securement systems are detached when the device has been properly positioned. The securement systems can be manipulated by control systems provided in the control portion of the delivery system.
