    advancing a distal end of a second intra-catheter stiffener element through the second lumen and out of the second distal opening;

    coupling the second intra-catheter stiffener element to the catheter;

    advancing the catheter into a blood vessel;

    uncoupling the first intra-catheter stiffener element from the catheter and removing the first intra-catheter stiffener element from the first lumen; and
