A method of deploying a prosthesis includes engaging a hub assembly of a handle to a threaded outer surface of a slide shaft of the handle； rotating the hub assembly to cause axial translation of the hub assembly and a sheath coupled to the hub assembly to initiate deployment of the prosthesis； disengaging the hub assembly from the threaded outer surface by pivoting a thread tooth of the hub assembly out of threaded engagement with the threaded outer surface； and sliding the hub assembly on the slide shaft to further retract the sheath and complete deployment of the prosthesis.
