Abstract
An improved method for expanding the open ends of human vessels employs an expandable cell which can be inflated a bubble at the open end of a vessel. The method is carried out with a novel closed end cell which can be connected to a source of fluidized pressure such a hypodermic syringe and, in its relaxed state can be introduced into the open end of the vessel for subsequent expansion into a bubble of the desired diameter to cause uniform length extension of the open end of the vessel. The cell may be prestressed or weakened to establish the location of bubble formation within the cell.
