A prosthesis delivery system and method of use thereof are described. The system includes a handle (22), an inner cannula (32) extending proximally from the handle, an outer sheath (30) extending proximally from the handle, and a pull member (110). The outer sheath (30) including an axially collapsible segment (50) and a non-collapsible body (51). The pull member (110) is coupled between the handle and the axially collapsible segment or the non-collapsible body of the outer sheath. The handle (22) is operable to retract the pull member (110) such that the axially collapsible segment is shortened. The handle (22) may include a spool and an actuator coupled to the pull member in a manner for winding the pull member around the spool. The handle (22) may be shorter than the retraction length of the axially collapsible segment sized for deployment of the prosthesis.
