Docking devices can be configured to be positioned at a native valve of a human heart to provide structural support for docking a prosthetic valve. The docking devices generally have coiled structures that define an inner space in which the prosthetic valve can be held. Some docking devices can be adjusted from a first wider configuration which facilitates easier advancement of the docking device around the valve anatomy, to a second narrower configuration after the docking device has been delivered to more securely hold the prosthetic valve. The docking device may also be better held in position at the native valve after adjustment to the narrower configuration. Some docking devices include a stabilization segment or double coil configuration, where a main coil region is configured to securely hold a prosthetic valve, while a stabilization coil region is configured to more stably hold the docking device at the native valve.
