Zusammenfassung:A method of delivering a valve prosthesis to be deployed within a native heart valve at a native heart valve annulus. The method including collapsing a prosthetic valve having an expandable frame comprising a proximal end and a distal end and a longitudinal axis extending therethrough inside of a delivery instrument, such that a plurality of spaced anchors extending from the distal end of the expandable frame towards the proximal end are collapsed to an inverted position in a collapsed anchor configuration. The method further including advancing the delivery instrument a first distance such that the plurality of spaced anchors extend below the valve annulus, and releasing each of the plurality of spaced anchors such that each of the plurality of spaced anchors is repositioned from the inverted position to an expanded anchor configuration to contact a subannular location.
