Abstract:
Systems for insufflation and recirculation of insufflation fluid in a surgical procedure include a control unit having a fluid pump, a supply conduit, a return fluid conduit and a pressure-controlled valve. The pressure-controlled valve is in fluid communication with an insufflation gas supply, the supply conduit and the return conduit and is adapted and configured to respond to pressure control signals to adjust position and thereby system flow parameters, to reduce entrainment of air from the surrounding environment, and to increase the concentration of insufflation gas in an operative space, and/or to reduce an overpressure condition in the operative space.

Claim (Index 19):
A surgical access device comprising:\n an elongated inner tubular member having opposed proximal and distal end portions and having a longitudinal axis extending therethrough, the inner tubular member defining a central conduit having an open proximal end and an open distal end, the open proximal end of the central conduit and the open distal end of the central conduit being centered around a longitudinal central axis of the device for passage of a surgical instrument therethrough, the inner tubular member having an outer surface; an elongated outer tubular member having opposed proximal and distal end portions and being arranged coaxially about the inner tubular member, the inner tubular member and the outer tubular member defining an outer conduit for receiving gas, the outer tubular member having an inner surface; wherein the outer surface of the distal end portion of the inner tubular member and the inner surface of the distal end portion outer tubular member are in direct surface to surface contact with one another such that the distal end portion of the inner tubular member and the distal end portion of the outer tubular member cooperate with one another to enclose a distal end of the outer conduit; wherein a distal end of the outer tubular member is located beyond a distal end of the inner tubular member; and wherein the distal end portion of the outer tubular member defines a plurality of apertures extending through the outer tubular member in fluid communication with the outer conduit.
