A hollow shaft extends outwardly from the forward end of the hub and has a lumen in fluid communication with the passageway. The shaft includes a closed distal end and an aperture in the side thereof near the distal end and in fluid communication with the lumen. A sleeve is slidably maintained on the shaft. During use, gases are vented by passing freely between the outside of the shaft and the inside dimension of the sleeve.
