A prosthetic valve delivery apparatus can comprise a handle, a gearbox, an input torque shaft and a plurality of output torque shafts. The input torque shaft can extend distally from the handle and can have a distal end portion operatively connected to the gearbox. The output torque shafts can be operatively connected to and extend distally from the gearbox. Rotation of the input torque shaft can cause rotation of the output torque shafts via the gear box.
