An occlusion device and a method of occluding a body vessel with the occlusion device are provided. The occlusion device has a sleeve that extends from a first end to a second end. The sleeve has an interior that extends to an opening at the first end. The occlusion device has tentacles that are attached to the first end and extend away from the sleeve. The tentacles reverse direction and extend into the interior to occlude the interior in response to fluid flowing toward the opening. A frame is attached to the first end of the sleeve.
