Abstract
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. Specifically, a petal-shaped occluder with a catch system is provided within a delivery sheath. In certain embodiments, the delivery system includes a first securement system for securing a first end of the occluder and a second securement system for securing a second end of the occluder to a delivery catheter and a delivery wire contained in the delivery system. The securement enable the deployment (and retrieval) of the device. The securement systems enable pushing and pulling of respective ends of the occluder to expand and contract the device by varying its axial length. In one aspect, the first securement system employs a threaded connection and the second securement system employs a suture connection. In another aspect, the first securement system employs a threaded connection and the second securement system employs a collet finger connection. 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.
