摘要：
A heart valve therapeutic device (1) has an elongate anchor (7) wherein the anchor has a stiffness to hold its shape and location to support the valve element. The anchor may have a stylet or a shaped or stiff collar (70) arranged to provide a desired shape to the anchor (7) and it may be lockable. A prosthetic valve element (15) has leaflets (17) and is supported on the anchor by coupler (16, 50) at a desired location. There is an actuator for changing relative axial position of the proximal and distal couplers (16, 50) on the anchor. The anchor stiffness may be sufficient to provide sufficient support to resist axial forces from the ventricle in use without necessarily having a fixing element engaging heart tissue. The prosthetic leaflets (240) may extend proximally and radially outwardly, so that there is excellent co-apting of the native leaflets (NL) against the prosthetic leaflets (240).
