Abstract
Methods and systems for implanting a helical anchor are disclosed. A method comprises, proximate a native heart valve, positioning a helical anchor arranged inside a shaft in a delivery configuration and a distal end of the shaft at a first position relative to one another such that the distal end of the shaft has a first radius of curvature, wherein the helical anchor has a coiled configuration comprising a plurality of turns after being delivered at the native heart valve. The method further comprises moving the helical anchor and the distal end of the shaft into a second position relative to one another such that the shaft has a second radius of curvature.

A method comprising:
- proximate a native heart valve, positioning a helical anchor arranged inside a shaft in a delivery configuration and a distal end of the shaft at a first position relative to one another such that the distal end of the shaft has a first radius of curvature, wherein the helical anchor has a coiled configuration comprising a plurality of turns after being delivered at the native heart valve;
- and
- moving the helical anchor and the distal end of the shaft into a second position relative to one another such that the shaft has a second radius of curvature.
A method comprising:
- proximate a native heart valve, positioning a helical anchor arranged inside a shaft in a delivery configuration into a first position relative to a distal end of the shaft such that the distal end of the shaft has a first radius of curvature, wherein the helical anchor has a coiled configuration comprising a plurality of turns after being delivered at the native heart valve;
- and
- advancing the helical anchor into a second position relative to the distal end of the shaft such that the distal end of the shaft has a second radius of curvature.
A method comprising:

- and
- advancing the distal end of the shaft into a second position relative to the helical anchor so that the shaft has a second radius of curvature, wherein the second radius of curvature is greater than the first radius of curvature.
