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