Heart valve docking system

A system for implanting a prosthetic valve in a native mitral valve of a heart, the system comprising:

• a prosthetic heart valve comprising a frame;
• a docking device comprising:
• a coiled body having an upper region, a central region, an ascending portion that connects the central region to the upper region, and a lower region, wherein the docking device is configured to be implanted at the native mitral valve with the upper region positioned in a left atrium of the heart, the lower region positioned in a left ventricle of the heart, and the central region positioned to extend around a plurality of leaflets of the native mitral valve;
• and
• a high friction sleeve positioned over a portion of the coiled body to cover an entirety of the central region and leave the ascending portion uncovered by the high friction sleeve, wherein the high friction sleeve has a higher coefficient of friction compared to portions of an exterior surface of the coiled body that are uncovered by the high friction sleeve to generate friction between the prosthetic heart valve and the high friction sleeve.
