Abstract
A system is in various embodiments configured to treat a native heart valve, such as to secure a prosthetic heart valve within a native valve. Embodiments of the system include a docking device with different coil portions, such as an upper coil and a lower coil, where the device is configured to assume an axially expanded state and an axially compressed state. In the axially expanded state, the entire upper coil can be positioned on a first side of the lower coil relative to the central axis and/or the entire upper coil and the entire lower coil have a positive pitch relative to each other. In the axially compressed state, at least a portion of the upper coil can be positioned on a second side of at least a portion of the lower coil opposite to the first side relative to the central axis and/or at least a portion of the upper coil has a negative pitch relative to at least a portion of the lower coil.
