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 17):
A surgical access device comprising:\n an elongated outer tubular member having opposed proximal and distal end portions and having a longitudinal axis extending therethrough, the outer tubular member having an open distal end; an elongated inner tubular member having opposed proximal and distal end portions and being arranged coaxially within the outer tubular member, the inner tubular member having an open distal end and defining a central conduit extending to the open distal end for passage of a surgical instrument therethrough; wherein portions of the inner and outer tubular members are spaced apart to define an outer conduit for receiving gas; wherein a plurality of circumferentially spaced apart apertures extends through the distal end portion of the outer tubular member and are in communication with the outer conduit; wherein an outer surface of the distal end portion of the inner tubular member is in direct contact with an inner surface of the distal end portion of the outer tubular member to enclose a distal end of the conduit at a location where an inside diameter of the outer tubular member is smaller than an inside diameter of portions of the outer tubular member that are spaced apart from the inner tubular member; and wherein the open distal end of the outer tubular member is located beyond the open distal end of the inner tubular member.
