摘要：
An occlusion device and method for occluding an undesirable passage through tissue, such as a septal defect, that provides an expandable cylinder or other structure that occludes the passage internally or by covering one or more openings to the passage. The occlusion device includes a wire lattice or mesh that expands from a contracted catheter-deliverable state to an expanded state that occludes the passage. The lattice or mesh has one or more layers, with layers that provide structural support to the device, and 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 passage.
