The system includes a handle, an inner cannula extending proximally from the handle, an outer sheath extending proximally from the handle, and a pull member. The outer sheath including an axially collapsible segment and a non-collapsible body. The pull member is coupled between the handle and the axially collapsible segment or the non-collapsible body of the outer sheath. The handle is operable to retract the pull member such that the axially collapsible segment is shortened. The handle 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 may be shorter than the retraction length of the axially collapsible segment sized for deployment of the prosthesis.
