1. A docking device for docking a prosthetic valve at a native valve of a heart, the docking device comprising:
a coiled anchor that comprises:
a proximal tip;
a distal tip;
at least one full central turn defining a diameter; and
an upper turn connected to the at least one full central turn;
a cover layer surrounding the coiled anchor along at least a part of the at least one full central turn, wherein the cover layer is connected to the coiled anchor; and
at least one friction enhancing layer disposed over the cover layer, wherein the at least one friction enhancing layer is disposed over at least a portion of the at least one full central turn and no portion of the upper turn is covered by the friction enhancing layer,
wherein the coiled anchor is configured to be implantable at the native valve with at least a portion of the at least one full central turn of the coiled anchor positioned in a chamber of the heart and around leaflets of the native valve.
