ABSTRACT:
A surgical cannula assembly is provided having a housing defining a channel extending from a proximal end to a distal end of the housing, at least one fluid flow regulator member disposed across the channel, which forms a substantial barrier to the passage of fluids in at least one direction, a cannula extending from the housing distal end in fluid communication with the channel, and a selector valve operatively connected to the cannula assembly housing and movable to at least a first orientation establishing a first fluid pathway from the channel to the environment outside the housing and a second orientation establishing a second fluid pathway from the channel to the outside environment.
