A prosthesis introducer system may include an introducer. A trigger wire release mechanism and a restraining member may be positioned near the distal end of the introducer. The system may include first and second trigger wires, each including a proximal portion releasably coupleable to a portion of a prosthesis and a distal portion coupled to the trigger wire release mechanism. The second trigger wire may be engaged by the restraining member. Each of the first and second trigger wires may include a taut portion. The second trigger wire may include a slack portion extending distally from the taut portion and positioned distal of the restraining member. Upon actuation of the trigger wire release mechanism, the first trigger wire may be releasable from the prosthesis and the second trigger wire may be releasable subsequent to the release of the first trigger wire.
