1. A method of delivery and implant of a prosthetic heart valve at a valve annulus, comprising:

  • providing a delivery system including;

    a handle shaft having a lumen therethrough; and

    an expansion catheter extending through the handle shaft having an expandable member on a distal end and a proximal end projecting proximally from out of the handle shaft, the expansion catheter being capable of linear movement relative to the handle shaft;

    providing a heart valve including a prosthetic valve having an expandable frame, the expandable frame having a contracted state for delivery to an implant position and an expanded state configured for outward connection to the annulus, the heart valve being mounted on the distal end of the handle shaft;

    advancing the distal end of the handle shaft so that the heart valve with the expandable frame in its contracted state is located at an implant position adjacent the annulus;

    displacing a safety member from engagement between a portion of the expansion catheter that projects from the handle shaft and a proximal end of the handle shaft, the safety member preventing distal movement of the expansion catheter relative to the handle shaft prior to displacement;

    displacing the expansion catheter distally so that the expandable member is located within the expandable frame; and

    actuating the expandable member to convert the expandable frame from its contracted state to its expanded state.
