Claim 6:
7. A system comprising:
a prosthetic heart valve comprising a frame that is radially expandable from a collapsed configuration to an expanded configuration, the frame having an inflow end and an outflow end; and
an anchor for docking the prosthetic heart valve, the anchor adapted to be held in a delivery catheter in an elongated configuration and delivered from the delivery catheter, and the anchor comprising an upper coil and a plurality of lower coils after being delivered from the delivery catheter, the plurality of lower coils adapted to support the prosthetic heart valve upon being fully delivered from the delivery catheter and implanted at a native heart valve of a heart, and the upper coil adapted to engage a wall of an atrium of the heart;
wherein the upper coil is adapted to be spaced axially from a native heart valve annulus of the native heart valve and, when the prosthetic heart valve is docked within the anchor, the upper coil extends axially beyond the inflow end of the frame of the prosthetic heart valve;
wherein the plurality of lower coils is adapted to be placed below the native heart valve annulus of the native heart valve such that the plurality of lower coils encircle native leaflets of the native heart valve and, when the prosthetic heart valve is docked within the anchor, the native leaflets are secured between the plurality of lower coils and the prosthetic heart valve; and
wherein the system further comprises a catheter and the delivery catheter, the delivery catheter disposed within the catheter and having a distal portion configured to extend distal to a distal end of the catheter, the distal portion of the delivery catheter transitionable into a curved shape when disposed outside the distal end of the catheter, and wherein the anchor is adapted to be delivered from the delivery catheter when the distal portion of the delivery catheter is disposed outside the distal end of the catheter.
