    slidingly disposing the dehydrated plug in a lumen of said coaxial needle;

    pre-hydrating said dehydrated plug by introducing a liquid-fluid solution into said lumen of said coaxial needle before displacing said prehydrated plug from said lumen;

    slidingly displacing said prehydrated plug within said lumen to a preselected location near a distal end of said lumen;

    withdrawing said coaxial needle while maintaining said prehydrated plug at said preselected location;

    whereby said pre-hydrated plug expands to fill said puncture opening in less time than a dehydrated plug that is not pre-hydrated.
