1. An anchoring system comprising:
a first anchoring device comprising a first attachment mechanism; and
a second anchoring device comprising a second attachment mechanism and a frame forming a closed loop, the second attachment mechanism forming a covering across the closed loop;
wherein:
the second attachment mechanism extends from the frame and does not extend beyond the frame;
each of the first anchoring device and the second anchoring device is configured to enter a tissue wall at a proximal side of the tissue wall;
at least a portion of the first anchoring device is configured to exit the tissue wall through a first hole on a distal side of the tissue wall;
at least a portion of the second anchoring device is configured to exit the tissue wall through a second hole on the distal side of the tissue wall;
the first attachment mechanism is configured to attach to the second attachment mechanism outside of the distal side of the tissue wall; and
the second attachment mechanism is configured to at least partially cover the first hole to prevent bleeding.
