Claim 7:
8. The device of claim 1, the wall of the internal body having an outer surface, and comprising a pattern of one or more porous areas and one or more non-porous areas, the device further comprising a movable shield external to and contacting the outer surface of the wall of the internal body, wherein the shield is configured to move from a closed position, that blocks the one or more porous areas of the internal body, thereby restricting passage of air into the internal body through the pores during aspiration of fat through a cannula attached to the cannula adaptor, and restricting passage of cells through the pores during fat injection through the cannula attached to the cannula adaptor, to an open position that permits passage of liquid through the one or more porous areas when the internal body is spun.
