A method of deploying a prosthesis includes restraining the prosthesis within a distal end of a sheath. A slide ring of a handle is rotated to initiate retraction of the sheath. In this manner, the prosthesis is initially very gradually released. The slide ring is then slid to complete retraction of the sheath and to deploy the prosthesis. In this manner, the sheath is easily and quickly retracted thus rapidly completing deployment of the prosthesis. Rapid deployment of the prosthesis facilitates faster procedure times, thus minimizing the period of time during which blood flow is occluded.
