1. A system for delivering a prosthetic heart valve, comprising:

  • a heart valve including a prosthetic valve having an expandable frame, the frame having a contracted state for delivery to an implant position and an expanded state configured for outward connection to the annulus;

    a valve holder attached to the heart valve and having a bore;

    an elongated handle shaft attached to a proximal end of the valve holder and having a lumen, a proximal end of the handle shaft having a handpiece;

    an expansion catheter extending through the handle shaft lumen and having an expandable member on a distal end sized to pass through the bore of the valve holder and a proximal end projecting proximally from out of the handpiece, the expansion catheter being axially movable relative to the handle shaft between a retracted position and an advanced position in which the expandable member is located within the expandable frame of the heart valve, wherein the expansion catheter is a balloon catheter and the expandable member is a balloon, and wherein a proximal end of the balloon catheter has a luer connector; and

    a safety member engaged between the expansion catheter and the handle shaft and preventing distal movement of the expansion catheter from its retracted position, the safety member covering the luer connector and preventing balloon inflation prior to removal.
