1. An anchoring device for use within a cardiovascular structure, comprising:
- a first radially expandable ring having a central axis extending in a longitudinal direction;
a plurality of legs extending from the first expandable ring in the longitudinal direction, each of the legs having first and second ends;
a second radially expandable ring forming a set of apices that point in a direction away from the first expandable ring, the second expandable ring being connected to each of the legs between the first and second ends thereof so that a portion of each of the legs extends from the second expandable ring between adjacent ones of the apices; and
an anchor connected to each of the legs and extending radially inwardly therefrom toward the central axis.
