1. An occluder for a defect in a body, the occluder comprising:

  • an occluder body that defines a longitudinal axis, the occluder body being reconfigurable, by an axially compressive force, from an elongated delivery configuration to a shortened and radially expanded deployed configuration, the occluder body comprising;

    a proximal side;

    a central portion that is positioned distal of the proximal side; and

    a distal side that is positioned distal of the central portion,wherein the proximal side comprises a proximal end portion and a plurality of proximal-side struts that extend between the proximal end portion and a proximal end of the central portion,wherein the distal side comprises a distal end portion and a plurality of distal-side struts that extend between a distal end of the central portion and the distal end portion,wherein the central portion comprises a plurality of central struts that each extend between the proximal end of the central portion and the distal end of the central portion,wherein the proximal end of the central portion comprises a plurality of proximal convergence areas and the distal end of the central portion comprises a plurality of distal convergence areas,wherein, when the occluder body is configured in the delivery configuration, each central strut of the plurality of central struts is arranged generally parallel to the longitudinal axis such that the plurality of central struts define a first cylinder having a first diameter,wherein, when the occluder body is configured in the deployed configuration, the proximal side comprises a plurality of proximal-side petal-shaped loops, the distal side comprises a plurality of distal-side petal-shaped loops, and the plurality of central struts are arranged in a zigzag pattern to define a second cylinder having a second diameter that is greater than the first diameter.
