1. An occluder for occluding a cavity in a patient, the occluder comprising:
a proximal disk that is formed of metallic wires that are braided into a wire mesh fabric, the metallic wires being nitinol shape memory wires, the proximal disk being self-expandable and set to a shape and size to cover an aperture leading to the cavity and to abut tissue surrounding the aperture, the proximal disk including a proximal hub having a threaded portion configured to reversibly connect to a delivery system;
a self-expandable body portion positioned distal to the proximal disk and sized and shaped to frictionally engage tissue of a wall that surrounds the cavity;
a transition section that couples the proximal disk to the body portion;
wherein in an expanded condition of the occluder, the proximal disk, the body portion, and the transition section each have a diameter, the diameter of the proximal disk being larger than the diameter of the body portion, and the diameter of the body portion being larger than the diameter of the transition section, and
wherein in the expanded condition of the occluder, the proximal disk has a length between a proximal end of the proximal disk and a distal end of the proximal disk, and the body portion has a length between a proximal end of the body portion and a distal end of the body portion, the length of the proximal disk being smaller than the length of the body portion.
