16. A delivery device that releasably attaches a sizer device or a holder device for delivery to and/or from a heart valve annulus, the device comprising:
-
an elongate shaft having a proximal end and a distal end, and a wire running there through; a handle attached to the proximal end of the shaft that is attached to the wire, wherein rotation of the handle moves the wire proximally and distally; and a socket moveable within the shaft and extendible from the distal end of the shaft and connected to the wire, wherein when the wire moves distally the socket moves distally and extends from the delivery device and when the wire moves proximally the socket also moves proximally and grasps a holder device or sizer device in order to attach the holder or sizer device to the delivery device. - View Dependent Claims (17, 18, 19, 20)
