Abstract
A tissue opening occluder comprising first and second occluder portions, each occluder portion including a frame structure and an attachment structure to attach one portion to the other portion. The frames may be utilized to constrain the tissue between the two portions enough to restrict the significant passage of blood therethrough. The frame portions may be covered by a fabric suspended from a perimeter thereof. The occluder portions are conjoined at least one point on each portion.

- deploying a tissue opening occluder comprising a support structure within the PFO tunnel between the overlapping atrial septa;
- and
- engaging an anchor element carried by the support structure with heart tissue from within the PFO tunnel once the support structure is positioned in the PFO tunnel, the anchor element piercing heart tissue from within the PFO tunnel to secure the occluder in position within the PFO tunnel.
