Abstract

A method can comprise deploying a prosthetic valve with a delivery apparatus, where the prosthetic valve comprises a frame and a rotatable screw connected to the frame, and where the screw comprises a screw head having an annular bore with internal threads. The delivery apparatus is releasably coupled to the screw and can comprise a first shaft and a first head disposed at an end of the first shaft, the first head comprising external threads releasably engaged with the internal threads of the screw head, and a second shaft that is coaxial with and surrounds the first shaft, the second shaft comprising a second head disposed at an end of the second shaft, the second head releasably engaged with an exterior surface of the screw head. Deploying the valve includes radially expanding the prosthetic valve by rotating the screw with the delivery apparatus.
