A prosthesis delivery device and method of using the same is described. The delivery device comprises a rotatable inner cannula (310) extending from a proximal end to a distal end with a prosthesis releasably coupled to the proximal end. A delivery handle assembly is disposed at the distal end of the delivery device. The handle comprises a first handle disposed about the inner cannula (310), a rotary dial disposed about the rotatable inner cannula and a second handle disposed about at least a portion of the distal end of the first handle. The second handle is longitudinally moveable relative to the first handle between a first position wherein the sheath is coaxially disposed about the prosthesis and rotation of the rotary dial is prevented, and a second position wherein the sheath is retracted distally to expose at least a portion of the prosthesis and rotation of the dial is permitted.
