Abstract

An assembly can comprise a prosthetic valve comprising a radially expandable and compressible frame and a rotatable screw connected to the frame, where the screw comprises a screw head having an annular bore with internal threads, and where the screw is rotatable to radially expand the frame. The assembly further comprises a delivery apparatus releasably coupled to the screw, the delivery apparatus comprising a first shaft and a first head disposed at an end of the first shaft, the first head comprising external threads configured to engage 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 is configured to releasably engage with an exterior surface of the screw head and rotate the screw.
