Claim 11:
12. A system, comprising:
an expandable implant comprising a replacement heart valve; and
a delivery apparatus for delivering the expandable implant to a body location of a native heart valve, the delivery apparatus comprising:
an inner assembly comprising a first segment and a second segment configured to rotate the expandable implant;
an outer sheath assembly having a proximal end and a distal end, the outer sheath assembly configured to cover a distal end of the expandable implant in a compressed configuration so that at least one anchor of the expandable implant extends distally;
a mid-shaft assembly configured to be translated proximally with respect to the inner assembly to expose a proximal portion of the expandable implant;
a nose cone attached to a distal end of a nose cone shaft; and
a handle located at a proximal end of the nose cone shaft and outer sheath assembly, the handle comprising a mid-shaft retraction knob and a deflection knob, wherein the handle comprises outer threads, wherein the handle is configured to allow rotation of the second segment of the inner assembly and the replacement heart valve relative to the outer sheath assembly, wherein rotation of the deflection knob is configured to push the mid-shaft assembly distally, and wherein when the mid-shaft retraction knob is rotated, the mid-shaft assembly and the deflection knob translate along the outer threads.
