1. A fluid transport system for selectively dispensing a fluid from within a pressure vessel, the pressure vessel comprising a housing having an interior surface defining a chamber, the pressure vessel further comprising an outlet opening having an inner diameter and being formed on the housing and an inlet opening having an inner diameter and being formed on the housing, the inlet opening and the outlet opening each effecting discrete fluid communication between the chamber of the pressure vessel and the exterior of the pressure vessel, the fluid transport system comprising:

  • (a) a delivery tube comprising a first end, an opposing second end being sealed closed, an exterior surface, and an interior surface defining a lumen extending between the first end and the second end;

    (b) containment means attached in sealed fluid communication with the first end of the delivery tube for forming a closed sterile environment capable of receiving and containing a fluid and for dispensing the contained fluid through the delivery tube when pressure is applied to the containment means; and

    (c) first sealing means disposed at a point along the delivery tube for effecting a pressure tight seal of the outlet opening without breaching the closed sterile environment of the containment means to enable pressurization of the chamber of the pressure vessel when the containment means is positioned within the chamber and the second end of the delivery tube is passed from within the chamber though the outlet opening so as to be outside of the pressure vessel.
