A delivery device for a prosthetic heart valve includes a shaft, a sheath, and a pull wire. The shaft has a proximal end, a distal end, and a longitudinal axis. The sheath is attached to the shaft and is rotatable about an axis transverse to the longitudinal axis of the shaft. The pull wire is mechanically coupled to the sheath such that movement of the pull wire rotates the sheath relative to the shaft. The sheath may be in a first position relative to the shaft when a distal end of the pull wire is in a first position and may be in a second position when the distal end of the pull wire is in a second position. Deflection of the sheath relative to the shaft enables a prosthetic valve to be axially aligned with the native valve annulus for deployment.
