Abstract:
1. A surgical access device comprising: a) an elongated outer tubular member having opposed proximal and distal end portions and having a longitudinal axis extending therethrough; 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 lumen for introduction of a surgical instrument therethrough; c) an insufflation conduit defined between the inner and outer tubular members in communication with a source of humidified insufflation gas; and d) a plurality of apertures extending through an outer surface of the distal portion of the outer tubular member in fluid communication with the insufflation conduit and configured to laterally discharge humidified insufflation gas from the insufflation conduit into the peritoneum of a patient, wherein the distal end portion of the outer tubular member and the distal end portion of the inner tubular member cooperate to enclose the insufflation conduit such that the humidified insufflation gas is discharged only from the plurality of apertures.
