1. An assembly, comprising:
a retrieval device for retrieving a previously implanted valve repair device on leaflets of a native valve;
the previously implanted valve repair device comprising:
an anchor portion comprising a pair of paddles;
a spacer coupled to and disposed between the pair of paddles;
wherein the spacer is configured to block blood flow through the spacer;
a collar disposed at a proximal end of the spacer;
the retrieval device comprising:
a catheter;
a retrieval shaft disposed within the catheter;
wherein the retrieval shaft is configured to be extended from the catheter;
one or more retrieval components coupled to the retrieval shaft, the one or more retrieval components comprising:
at least one securing member selected from the group consisting of a wire loop, a snare, a lasso, a ring, a hoop, a clip, a magnet, a detent mechanism, and a coupler;
wherein the securing member becomes attached to the collar while the previously implanted device is implanted on the leaflets of the native valve;
at least one actuation member selected from the group consisting of a rod, a shaft, a bar, a wire, a line, a hook, and a suture;
wherein the actuation member becomes engaged with the anchor portion while the previously implanted device is implanted on the leaflets of the native valve; and
wherein the securing member and the actuation member are configured such that moving the actuation member relative to the securing member moves the pair of paddles of the anchor portion of the previously implanted device from a closed configuration to an open configuration.
