1. A system comprising:
a prosthetic heart valve that is radially expandable; and
an anchor for docking the prosthetic heart valve, the anchor comprising a plurality of helical coils transitionable to a straightened configuration to be held in a coil guide catheter;
wherein the plurality of helical coils is adapted to support the prosthetic heart valve upon being fully delivered from the coil guide catheter at a native heart valve of a heart and implanted with respective portions above and below a native heart valve annulus of the native heart valve, wherein the plurality of helical coils includes a lower portion comprising a plurality of lower coils and an upper portion comprising at least one upper coil, wherein the upper portion is adapted to be placed above the native heart valve annulus and wherein the plurality of lower coils is configured to encircle heart valve leaflets of the native heart valve;
wherein the at least one upper coil is configured to engage a wall of an atrium of the heart at a position spaced away from the native heart valve annulus after being delivered from the coil guide catheter, and wherein the at least one upper coil extends beyond an inflow end of a frame of the prosthetic heart valve when the prosthetic heart valve is docked within the anchor; and
wherein the system further comprises a catheter and the coil guide catheter, the coil guide catheter disposed within the catheter and configured to extend distally from a distal end of the catheter and wherein the coil guide catheter includes a stem portion and a distal portion, the stem portion and the distal portion configured to extend distally from the distal end of the catheter at the native heart valve, the distal portion connected to the stem portion at a first curved shape, the distal portion having a second curved shape configured to generally follow a curvature of the native heart valve annulus, the first and second curved shapes of the distal portion capable of being delivered in straightened configurations and activated to the first and second curved shapes within the heart proximate the native heart valve.
