Claim 14:
15. An assembly comprising:
a heart valve coaptation device comprising a clip configured to independently capture only a single leaflet of a native heart valve, be released from the catheter and remain attached to the single leaflet when the catheter is withdrawn, the clip comprising:
a metal inner frame member comprising curved support frame members, wherein the metal inner frame member is configured to be positioned on an atrial side of a leaflet of a heart valve;
a fabric covering disposed over the single metal inner frame member to increase a surface area of the curved support frame members;
a metal outer frame member coupled to the metal inner frame member, wherein the metal outer frame member comprises a barbed leaflet engagement portion, wherein the barbed leaflet engagement portion of the metal outer frame member is configured to be positioned on a ventricular side of the leaflet of the heart valve;

a catheter releasably coupled to the metal inner frame member;
an actuating suture attached to the barbed leaflet engagement portion of the metal outer frame member;
wherein applying tension to the actuating suture pulls the barbed leaflet engagement portion of the metal outer frame member distally to form an opening between the barbed leaflet engagement portion of the metal outer frame member and the metal inner frame member that is configured to accept the leaflet of the heart valve between the barbed leaflet engagement portion of the metal outer frame member and the metal inner frame member; and
wherein releasing the tension of the actuating suture allows resiliency of the metal outer frame member to move the barbed leaflet engagement portion of the metal outer frame member proximally and close the barbed leaflet engagement portion of the metal outer frame member and thereby capture the leaflet of the heart valve between the metal inner frame member and the barbed leaflet engagement portion of the metal outer frame member with the metal inner frame member on the atrial side of the leaflet of the heart valve and the barbed leaflet engagement portion of the metal outer frame member on the ventricular side of the leaflet.
