Summary:An anvil assembly 10 for use with a circular surgical stapling device having a housing 12 and venting means, in the form of vent holes 20, 22, for venting the interior of the anvil assembly. The housing includes channeling means 46, 48 in the form of a plurality of longitudinally extending and radially spaced surface grooves in an outer surface of the housing which are communicable with the vent holes to aid in directing a flow of air between the vent holes and the outer surface of the housing member to significantly reduce a suction effect therebetween. The channeling means further allows extruded tissue and debris to flow freely from the vent holes.
