摘要：
An occlusion device and method for occluding an undesirable vascular structure, such as a septal defect or left atrial appendage. The occlusion device includes a lattice structure that expands from a contracted catheter-deliverable state to an expanded state that occludes the vascular structure. The lattice structure has one or more braided layers, with structural braided layers that provide structural support to the device, and occlusive layers that provide a lattice braiding or pore sizes that promote further occlusion by a biological process, such as tissue ingrowth that further occludes the affected vascular structure.
