Abstract

In one representative embodiment, an implantable prosthetic device comprises a spacer body portion configured to be disposed between native leaflets of a heart, and an anchor portion configured to secure the native leaflets against the spacer body portion. The prosthetic device can be movable between multiple configurations. The spacer body can be made from braided, self-expandable metallic thread. A delivery apparatus can have a first shaft and a second shaft, wherein movement of the first shaft relative to the second shaft moves the anchor portion relative to the spacer body.
