Abstract:
1. An occlusion device having a right end and having a left end that is insertable through a septal defect, the occlusion device comprising: a center post extending to the left end of the occlusion device; a right occluding body comprising a first plurality of arms attached to the center post at radially innermost ends, wherein the center post extends through the right occluding body; a left occluding body comprising a second plurality of arms attached to the center post at radially innermost ends, the left occluding body being located closer to the left end of the occlusion device and the right occluding body being located closer to the right end of the occlusion device; a plurality of puller arms attached to the right occluding body for collapsing the right occluding body from a fully radially open state to a radially collapsed state, the puller arms being located on a right side of the right occluding body; a floating center located at the right end of the occlusion device external to the right occluding body and connected to the puller arms at a position to the right of both the right and left occluding bodies; and a grasping knob located on a right end of the floating center, wherein the floating center is engaged with the center post without being latched when the right occluding body is in its fully radially open state, and is movable away to the right from the center post by force applied to the grasping knob in a direction to the right to cause the puller arms to radially collapse the right occluding body.
