    Abstract: 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.

    Abstract: A delivery apparatus for a medical device implant can include an outer catheter and a flexible delivery catheter. The outer catheter can have an axially extending shaft and a first lumen extending co-axially through the axially extending shaft. The flexible delivery catheter can have an elongate shaft having a flexible section extending along a distal portion of the elongate shaft, and the flexible section of the elongate shaft can be positioned or adjusted between a first, delivery configuration and a second, activated configuration. The delivery catheter can have a pull wire extending co-axially through a second lumen axially extending through the elongate shaft. A distal end of the pull wire can be fixedly secured or attached to the distal end of the elongate shaft.

    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.
