HEART VALVE DOCKING DEVICES AND IMPLANTING METHODS
First Claim
1. A device for implanting at a native heart valve of a heart of a patient, the device comprising an upper coil and a lower coil, and a central axis extending through the upper coil and the lower coil;
- wherein the device is configured to assume an axially expanded state wherein the entire upper coil is positioned on a first side of the lower coil relative to the central axis; and
wherein the device is configured to assume an axially compressed state wherein at least a portion of the upper coil is positioned on a second side of at least a portion of the lower coil opposite to the first side relative to the central axis.

Abstract
A device is in various embodiments configured to repair a native heart valve or to secure a prosthetic heart valve within a native valve of the heart of a patient. Embodiments of the device include at least an upper coil and a lower coil, where the device is configured to assume an axially expanded state where the entire upper coil is positioned on a first side of the lower coil relative to the central axis, and an axially compressed state where at least a portion of the upper coil is positioned on a second side of at least a portion of the lower coil opposite to the first side relative to the central axis.
