A delivery device for a prosthetic heart valve includes a proximal sheath and a distal sheath. The proximal sheath has a distal end disposed at an oblique angle relative to the longitudinal axis of the proximal sheath, and the distal sheath has a proximal end disposed at an oblique angle relative to the longitudinal axis of the distal sheath. The distal end of the proximal sheath and the proximal end of the distal sheath mate so that rotation of the distal sheath relative to the proximal sheath causes the distal sheath to deflect from coaxial alignment with the proximal sheath. Deflection of the distal sheath relative to the proximal sheath enables the prosthetic valve to be axially aligned with the native valve annulus for deployment.
