OCCLUSION DEVICE HAVING FIVE OR MORE ARMS

摘要

An occlusion device (10) having at least five arms (20). Though the number of arms (20) is increased, the diameter of each arm (20) is reduced. As a result, the increased number of arms (20) provides the desired tension as the occlusion device (10) is deployed and provides the desired strength to hold the occlusion device (10) in place and properly occlude the defect. At the same time, the reduced diameter of the arms (20) improves the cycle life of the occlusion device (10). Furthermore, the increased number of arms (20) provides for better sealing across the defect and reduces residual shunting.
