First Claim
Patent Images
1. A system for implanting a docking device at a native valve, the system comprising:
- a delivery catheter;
an elongated coiled docking device having an end portion;
a pusher device having a central lumen, wherein the pusher device is disposed in the delivery catheter;
a retrieval line that extends through the central lumen of the delivery catheter and is coupled to the end portion of the coiled docking device;
wherein the system is configured such that pulling the retrieval line pulls the end portion of the coiled anchor against the pusher device; and
wherein the end portion and retrieval line are configured and coupled such that a tension force from the pulling is biased to be substantially aligned with a central axis of the end portion of the coiled docking device.

Abstract
Docking devices for docking a prosthetic valve at a native valve of a heart can include a coiled docking anchor and a retrieval suture. The docking device and retrieval suture can be configured for improved retention and retrieval of the docking device after deployment. The docking devices can have an end portion with a central axis. The retrieval suture can be connected to the end portion such that a line of force applied by applying tension to the retrieval suture is substantially aligned with the central axis.
