Beschreibung
Zusammenfassung:	Delivery systems and methods for delivering a valve anchor and a valve prosthesis to a native valve annulus are provided. The anchor can be deployed near the native valve annulus with a tether attached thereto. A portion of the tether can be positioned inferior to the deployed anchor in an inverted configuration for advantageous positioning for adjusting the anchor position and/or deployment of the valve prosthesis. A positioning tool can be tracked over the tether and used to properly position the anchor. The positioning tool can be configured to transition to a stiffened state that includes one or more bends configured to allow efficient positioning of the deployed anchor and to provide room for deploying the valve prosthesis. Once the anchor is properly positioned, the valve prosthesis can be deployed within the native valve annulus and within the valve anchor.
