1. A method of reducing heart valve regurgitation, comprising:
advancing an implant in a delivery configuration to a heart valve via a delivery device, the implant comprising a first arm, a second arm and a plurality of support members each extending from the first arm to a respective free end and being in a curved and elongated state when the implant is in the delivery configuration;
separating the first and second arms by applying tension to a tether routed through at least one of a plurality of holes (1) of the first arm, or (2) of the second arm;
positioning the first arm on a first side of a native leaflet of the heart valve and the second arm on a second, opposite side of the native leaflet of the heart valve; and
releasing at least one of the first and second arms to couple the implant to one or more of a native leaflet or chordae tendineae of the heart valve.
