Abstract
A device for aseptic delivery of biological material from a vial includes a tubular barrel, a filter assembly, and a dispersion funnel assembly. The tubular barrel includes a receiving end to accept at least a portion of the vial within the tubular barrel, and a dispensing end opposite the receiving end. The filter assembly is fluidly connected to the dispensing end of the tubular barrel. The dispersion funnel assembly is configured to connect to the vial, and to be disposed at least partially within the tubular barrel. The dispersion funnel assembly has an open configuration to disperse the biological material from the vial into the tubular barrel between the dispersion funnel assembly and the filter assembly, and a closed configuration to force the dispersed biological material through the filter assembly when the dispersion funnel assembly is moved toward the dispensing end of the tubular barrel.
