Patent attributes
A bone void filler preparation system that includes a processing vessel, a processing piston, a bone void filler preparation container and tubing. The processing vessel has a recess formed therein. The processing vessel is adapted to receive bone marrow aspirate. The processing piston includes an outer wall, a central wall member and a connection port. The outer wall has an upper edge and a lower edge. The central wall member extends inwardly from the outer wall intermediate the upper and lower edges of the processing piston. The central wall member has an aperture formed therein. The central wall member has a downwardly directed portion that defines an air-retaining region. The air-retaining region is closer to the outer wall upper edge than the aperture. The connection port is operably connected to the aperture. The processing piston is movable in the processing vessel recess. The bone void filler preparation container has an inlet portion and an outlet port. The bone void filler preparation container is adapted to receive a bone void filler matrix therein. The tubing fluidly connects the processing piston connection port and the bone void filler preparation container inlet port.
