Claim 0:
1. A device for aseptic delivery of biological material from a vial, the device comprising:
a tubular barrel comprising:
a receiving end to accept a portion of the vial within the tubular barrel; and
a dispensing end opposite the receiving end;

a filter assembly fluidly connected to the dispensing end of the tubular barrel; and
a dispersion assembly having a proximal end configured to couple to the vial and a distal end opposite the proximal end, the dispersion assembly configured to be at least partially disposed within the tubular barrel, the dispersion assembly comprising:
a dispersion element configured to be in fluid communication with the vial to disperse the biological material from the vial, the dispersion element comprising a wall forming a plurality of openings through the wall;
a piston disposed at the distal end of the dispersion assembly, the piston in sealing contact with the tubular barrel; and
a one-way valve forming a fluid passageway in fluid communication with the dispersion element and the tubular barrel, the one-way valve configured to allow a flow of the dispersed biological material from the dispersion element, through the fluid passageway, and into the tubular barrel, and to prevent a flow of the dispersed biological material from the tubular barrel into the dispersion assembly;

wherein the filter assembly includes a filter medium, the filter assembly selectable between an open state wherein the filter medium prevents the biological material from passing through the filter assembly but permits liquid to pass through the filter assembly, a bypass state wherein the biological material can pass through the filter assembly to deliver the biological material, and, optionally, a closed state wherein no liquid or biological material can pass through the filter assembly.
