Abstract
A surgical access device includes a cannula, an instrument housing coupled to the cannula, a port coupled to the instrument housing, and a valve disposed within the port. The cannula includes an elongated shaft defining an access lumen and an inflation lumen therethrough. The port includes an inflation channel and an insufflation channel defined therethrough. The inflation channel is in fluid communication with the inflation lumen of the cannula and the insufflation channel is in fluid communication with the access lumen of the cannula. The valve is movable within the port between an inflation position in which a passageway defined through the valve is aligned with the inflation channel of the port, and an insufflation position in which the passageway of the valve is aligned with the insufflation channel of the port.
