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 21):
A surgical access device comprising:\n a) 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; b) 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 defining a central conduit extending to an open distal end that is axially aligned with the open distal end of the outer tubular member, wherein the central conduit of the inner tubular member and the open distal end of the outer tubular member are dimensioned and configured for passage of a surgical instrument therethrough; c) an outer conduit defined between the inner and outer tubular members for receiving gas; and d) a plurality of circumferentially spaced apart apertures extending through a distal end portion of the outer tubular member in communication with the outer conduit, wherein an outer surface of the distal end portion of the inner tubular member and an inner surface of the distal end portion of the outer tubular member are in direct surface to surface contact with one another so that the distal end portion of the outer tubular member and the distal end portion of the inner tubular member cooperate with one another to enclose a distal end of the outer conduit, and wherein the open distal end of the outer tubular member is located distal to the open distal end of the inner tubular member.
