1. A medical device comprising: a plurality of struts forming a plurality of openings, the plurality of struts forming a plurality of bifurcations and being configured to form an annular shaped structure with the openings extending generally parallel to a longitudinal axis of the medical device; and
1. A medical device comprising: a plurality of struts forming a plurality of openings, the plurality of struts forming a plurality of bifurcations and being configured to form an annular shaped structure with the openings extending generally parallel to a longitudinal axis of the medical device; anda plurality of tissue engaging portions, each tissue engaging portion extending from a location between two longitudinally spaced bifurcations of the plurality of bifurcations, wherein the annular shaped structure is configured to radially move from an expanded state to a non-expanded state where the medical device occludes an opening in tissue into which the plurality of tissue engaging portions engage, while maintaining the openings extending generally parallel to the longitudinal axis of the medical device. 2. The medical device of claim 1, wherein each opening is a generally parallelogram-shaped opening and is configured to receive tissue. 3. The medical device of claim 1, wherein adjacent struts of the plurality of struts form a curved apex at one or more of the plurality of bifurcations. 4. The medical device of claim 1, wherein each opening has a mid-portion having a width in a direction transverse to a longitudinal axis of the opening greater than widths of a remainder of the opening, each tissue engaging portion being coupled to the mid-portion. 5. The medical device of claim 1, wherein each tissue engaging portion extends away from the opening to engage tissue disposed adjacent to the tissue engaging portion. 6. The medical device of claim 1, wherein the plurality of tissue engaging portions are disposed substantially symmetrically about the longitudinal axis. 7. The medical device of claim 1, wherein the openings are biased toward an expanded, deployed configuration. 8. The medical device of claim 1, wherein two adjacent struts of the plurality of struts are coupled together at a hinged region. 9. The medical device of claim 1, wherein the medical device includes 5 or more openings. 10. The medical device of claim 1, wherein the plurality of openings is configured to aid with reducing a profile of the medical device in a pre-deployed configuration. 11. The medical device of claim 1, wherein the plurality of struts form a plurality of looped elements that form the openings. 12. The medical device of claim 1, wherein each looped element has an inner curved region and an outer curved region. 13. The medical device of claim 12, wherein the inner curved region is out of phase with the outer curved region. 14. The medical device of claim 1, wherein the plurality of struts form a zig-zag pattern. 15. The medical device of claim 1, wherein the plurality of struts cooperate with a plurality of curved regions to form a looped periphery. 16. The medical device of claim 15, further comprising a plurality of tissue penetrating portions associated with the plurality of struts and spaced apart from the looped periphery. 17. The medical device of claim 16, wherein the plurality of tissue penetrating portions include tissue stops to limit tissue penetration. 18. The medical device of claim 1, wherein the plurality of tissue engaging portions extend distally from a proximal end of the plurality of openings. 19. The medical device of claim 1, the plurality of struts cooperate with a plurality of curved regions to form a curved periphery. 20. The medical device of claim 1, wherein the openings are square-shaped. 21. The medical device of claim 1, wherein the plurality of struts are configured to move the plurality of tissue engaging portions.
