摘要：
Devices and methods for occluding blood flow into a body cavity are disclosed herein. An occlusion device can include an expandable lattice structure having an occlusive braid and a structural braid. In some embodiments, the structural braid is enveloped by the occlusive braid, and the occlusive braid is configured to contact and seal with tissue. The structural braid can have a first pick angle and the occlusive braid can have a second pick angle that is greater than the first pick angle. In some embodiments, the occlusion device is configured to occlude the left atrial appendage.
