Abstract
A surgical access device includes a housing having a tubular member extending therefrom. The tubular member has inner and outer walls defining an annular lumen therebetween. A passageway extends between proximal and distal openings of the tubular member. The passageway is configured to receive a surgical instrument therethrough. A conduit is disposed in the annular lumen and includes spiral segments where each spiral segment is engaged with an adjacent spiral segment. The conduit is flexible in a first state and is fixed in a second state. A valve assembly is coupled to the housing and includes a port that is in fluid communication with the annular lumen. The port is attachable to a source of fluid.
