HEART VALVE DOCKING COILS AND SYSTEMS
First Claim
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 and a distal tip;
at least one central turn having a first thickness and defining a central turn diameter;
an extension having a length extending from an upper end of the at least one central turn, the extension having a second thickness that is less than the first thickness;
an upper turn extending from an upper end of the transition portion, the upper turn having a third thickness that is greater than the second thickness; and
wherein the coiled anchor is configured to be implanted at the native valve with at least a portion of the at least one central turn of the coiled anchor positioned in a chamber of the heart and around valve leaflets of the native valve.

Abstract
Anchoring or docking devices configured to be positioned at a native valve of a human heart and to provide structural support for docking a prosthetic valve therein. The docking devices can have coiled structures that define an inner space in which the prosthetic valve can be held. The docking devices can have enlarged end regions with circular or non-circular shapes, for example, to facilitate implantation of the docking device or to better hold the docking device in position once deployed. The docking devices can be laser-cut tubes with locking wires to assist in better maintaining a shape of the docking device. The docking devices can include various features to promote friction, such as frictional cover layers. Such docking devices can have ends configured to more securely attach the cover layers to cores of the docking devices.
