1. A method for withdrawing, crimping, and loading a stent-mounted valve from a storage container into a delivery catheter for the performance of a transcatheter valve implantation procedure, the method comprising:

  • attaching a loading tool to a substantially open state stent-mounted valve inside a storage container using a connector of the loading tool in an open state, wherein the connector is configured to be removably connected to the stent-mounted valve, and wherein the loading tool is configured to be coupled to an inner shaft of a delivery catheter;

    withdrawing the stent-mounted valve from the storage container using the loading tool;

    advancing the stent-mounted valve and the connector of the loading tool through a generally converging-shape crimping tool using the loading tool such that the stent-mounted valve becomes crimped and the connector of the loading tool radially contracts from the open state to a closed state;

    coupling the loading tool to the inner shaft of the delivery catheter; and

    retracting the stent-mounted valve and the loading tool into the delivery catheter.
