Abstract
Methods and apparatus are provided for repairing or replacing a defective cardiac valve including a prosthetic leaflet assembly having an expandable frame with one or more anchors configured to engage a predetermined region of the defective cardiac valve in an expanded deployed state, and at least one prosthetic leaflet coupled to the expandable frame. The prosthetic leaflet assembly is configured such that the prosthetic leaflet is suspended within a flow path of the defective cardiac valve and coapts with, and improves functioning of, one or more native leaflets of the defective cardiac valve.
