1. A medical device for sealing a defect or structure in a heart, the medical device comprising:
a wire frame that includes a plurality of wires that each extend from a proximal end of the wire frame to a distal end of the wire frame, the wires forming:
a first wire aggregation element defining a proximal eyelet near the proximal end of the wire frame and a second wire aggregation element defining a distal eyelet near the distal end of the wire frame, the first wire aggregation element formed from first end portions of each wire of the plurality of wires, and the second wire aggregation element formed from second end portions of each wire of the plurality of wires;
a first occluding member disposed adjacent the first wire aggregation element, each wire of the plurality of wires forming a respective petal of the first occluding member, wherein adjacent petals of the first occluding member overlap one another and are not interwoven with one another;
a second occluding member disposed adjacent the second wire aggregation element, each wire of the plurality of wires forming a respective petal of the second occluding member, wherein adjacent petals of the second occluding member overlap one another and are not interwoven with one another; and
a defect-occupying portion disposed between the first occluding member and the second occluding member, wherein each wire of the plurality of wires includes, in the defect-occupying portion, a first generally linear segment, a second generally linear segment, and a curved segment disposed between the first generally linear segment and the second generally linear segment; and
a sealing member configured with one or more openings defining passages through the sealing member, the sealing member disposed on the frame such that the one or more openings are located on one or both of the first occluding member and the second occluding member and the one or more openings are configured to relieve a fluid pressure differential between an interior and an exterior of the sealing member.
