1. A foreign material exclusion device, comprising: a body, comprising a resilient material comprising one or more of a polymer foam and a rubber foam, wherein the body has an uppermost surface, a lowermost surface and a side surface located between the uppermost surface and the lowermost surface;an enclosure having a plurality of panels connected by sewing or adhering, the enclosure having at least two flaps that can be operatively connected to each other by a fastener assembly to enclose the body within the enclosure, wherein the enclosure is substantially conformable to the shape of the body, wherein the enclosure comprises fabric material made from fibers, wherein the body uppermost surface, the body lowermost surface and the body side surface are each in direct contact with an inner surface of the enclosure, wherein the enclosure generally conforms to the dimensions of the body; anda retrieval aid, directly connected to the enclosure, andwherein the body is resilient in nature so that it is adapted to be compressed to fit into a desired opening, and yet re-expand to provide a snug fit within or about the opening, wherein the enclosure includes a connector segment connected to an interior surface thereof, and wherein the retrieval aid is connected to the connector segment, wherein the device further includes an internal support device that is located within the enclosure and extends between an upper surface and a lower surface of the body, and wherein the retrieval aid extends through a passageway in the internal support device. 2. The device according to claim 1, wherein at least one flap includes a flap aperture, extending through a surface of the flap, through which a portion of the retrieval aid extends. 3. The device according to claim 1, wherein three or more flaps are present, each including a separate aperture through which a portion of the retrieval aid extends. 4. The device according to claim 3, wherein the connector segment is in the form of a loop that is connected on a lower, interior surface of the enclosure. 5. A foreign material exclusion device, comprising: a body, comprising a resilient material comprising one or more of a polymer foam and a rubber foam, wherein the body has an uppermost surface, a lowermost surface and a side surface located between the uppermost surface and the lowermost surface;an enclosure conformable to a shape of the body, wherein the enclosure encases the body and prevents the body from being separated from the device, wherein the enclosure comprises fabric material made from fibers, wherein the body uppermost surface, the body lowermost surface and the body side surface are each in direct contact with an inner surface of enclosure, wherein the enclosure generally conforms to the dimensions of the body; anda retrieval aid removably and directly connected to an interior surface of the enclosure and extending through a portion of the body and out of the enclosure through an enclosure aperture, and wherein the retrieval aid is a line, cord or cable, andwherein the body is resilient in nature so that it is adapted to be compressed to fit into a desired opening, and yet re-expand to provide a snug fit within or about the opening, wherein the retrieval aid extends through the body between a lower surface and an upper surface of the body. 6. The device according to claim 5, wherein the enclosure has an upper surface including a flap having a flap aperture extending through a surface of the flap, and wherein a portion of the retrieval aid extends through the flap aperture and out of the enclosure. 7. The device according to claim 6, wherein a plurality of flaps are present, wherein a first flap is connected to a second flap via a fastener assembly. 8. The device according to claim 5, wherein the enclosure has a connector segment on a lower interior surface thereof and the retrieval aid is connected to the connector segment. 9. The device according to claim 8, wherein three or more flaps are provided on the upper surface of the enclosure that can be folded such that at least one flap overlaps a second flap in order to encase the body within the enclosure. 10. A foreign material exclusion device, comprising: a body, comprising a resilient material comprising one or more of a polymer foam and a rubber foam, wherein the body has an uppermost surface, a lowermost surface and a side surface located between the uppermost surface and the lowermost surface;an enclosure that encases the body within the enclosure, wherein the enclosure comprises fabric material made from fibers, wherein the body uppermost surface, the body lowermost surface and the body side surface are each in direct contact with an inner surface of enclosure, wherein the enclosure generally conforms to the dimensions of the body;an internal support device that is a component distinct from the enclosure, and located completely within the enclosure that extends through at least a portion of the body; anda retrieval aid that is distinct from the enclosure and the internal support device and removably and directly connected to an interior portion of the enclosure and extending through the internal support device and out of the enclosure, and wherein the retrieval aid is a line, cord or cable, andwherein the body is resilient in nature so that it is adapted to be compressed to fit into a desired opening, and yet re-expand to provide a snug fit within or about the opening. 11. The device according to claim 10, wherein the enclosure has an upper surface including a flap having a flap aperture, and wherein a portion of the retrieval aid extends through the flap aperture and out of the enclosure. 12. The device according to claim 11, wherein a plurality of flaps are present, wherein a first flap is connected to a second flap via a fastener assembly. 13. The device according to claim 12, wherein three or more flaps are provided on the upper surface of the enclosure that can be folded such that at least one flap overlaps a second flap in order to encase the body within the enclosure. 14. The device according to claim 10, wherein the retrieval aid extends through the body between a lower surface and an upper surface of the body. 15. The device according to claim 14, wherein the enclosure has a connector segment on a lower interior surface thereof and the retrieval aid is connected to the connector segment.
